Answer:
Food Preservation. The processes by which the perishable food materials are treated to prevent their spoilage and retain their nutritive value for long periods
is called food preservation.
The substances used for food preservation are called food preservatives.
Different Methods of Food Preservation:

1. Dehydration and Sun Drying.
The process of removal of water from fruits, vegetables is called dehydration. It reduces the moisture content of food materials and, therefore, prevents the food from spoilage. Drying in the sun is one of the oldest methods of food preservation.

2. Preservation by Salt and Sugar.
Common salt and sugar are good preservatives. These stop the bacterial growth in the food material. Pickles, jam, jelly, ketchup, squash, etc. are preserved by adding salt and sugar.

3. Deep Freezing. It is a direct method for the prevention of bacterial growth. In this method, the food materials are cooled below 0 C. Fruits vegetables, meat, fish, etc. can be easily preserved by this method.

4. Chemical Preservation. Certain chemicals can be used to preserve food. The substances which are added to the food materials to prevent their spoilage are called food preservatives. Benzoic acid, Potassium metabisulphite, etc. can be used. Irradiation, canning, and bottling are also used for the preservation of food.

Fossil fuels are formed from remains of dead organisms and it took million of years to get these organisms converted into fuels. The known reserves of these fuels are limited and so, these are exhaustible fuels.

Question 7.
Describe the characteristics and uses of coke.
Answer:
Characteristics of Coke:

  1. It is tough, porous and black substance.
  2. It is pure form of carbon.

Uses of Coke:

  1. It is used to manufacture artificial graphite.
  2. It is used in manufacture of calcium carbide required for manufacture of acetylene gas. Acetylene gas is the basic raw material for manufacture of acetic acid and P.V.C.
  3. It is used in manufacture of water gas and producer gas used as an important fuel.
    • Water gas is not single gas. It is a mixture of equal volumes of carbon monoxide and hydrogen.
    • Producer gas is produced by passing controlled amount of air over red hot coke. Producer gas is in fact a mixture of one part of carbon monoxide and two parts of nitrogen by volume.
  4. It is used to extract metals like copper, iron, zinc, lead, tin etc., from their ores.
  5. Since coke does not produce any smoke, hence it is used as a household fuel.

Question 8.
Explain the process of the formation of petroleum.
Answer:
Formation of Petroleum.
Petroleum is formed from the bacterial decomposition of the remains of animals and plants which got buried under the sea millions of years ago. When these organisms died, they sank to the bottom and got covered by sand and clay. Over a period of millions of years, these remains got converted into petroleum oil by heat, pressure and catalytic action. The hydrocarbons formed rose through porous rocks until they were trapped by impervious rocks forming an oil trap. Natural gas is found above the surface of petroleum oil.

Long Answer Type Questions

Question 1.
What are fossil fuels ? How are they formed ? Why are they called non¬renewable sources of energy ?
Answer:
Petroleum, natural gas, coal etc., are main forms of fossil fuels. Millions of years ago, remains of animals, plants got buried under the earth before dinosaurs. These remains are called fossils. They remained inside the earth under huge pressure and high temperature in the absence of oxygen, these remains got converted into fossil fuel.

Fossils as a source of non-renewable source of energy.
Fossils were formed several hundred years ago under the earth. Man uses these for his various activities. These cannot be regained after use. So they are called non-renewable source of energy.

Question 2.
Describe the formation of
(a) Coal
(b) Petroleum.
Answer:
(a) Coal Formation.
Coal is believed to be formed from fossils which got buried inside the earth during earthquakes, volcanic eruptions etc., which occurred about 300 million years ago. These fossils were covered with sand, clay and water. In the absence of air and under high temperature and high pressure inside the earth, the fossils got converted into coal. This process of conversion of plants and animals buried inside the earth under high temperature and pressure to coal is called carbonisation. It is a very slow process and may have taken thousands of years.

(b) Formation of Petroleum.
It is believed that petroleum was formed and preserved in its crude state in the earth from the remains of dead microscopic marine plants (phytoplankton) which settled in muddy sediments at the bottom of sea millions of years ago. Prolonged sedimentation and cooking of these organic debris under pressure in the presence of natural catalysts, converted them into petroleum . For this reason, petroleum is also called fossil fuel.
PSEB 8th Class Science Solutions Chapter 5 Coal and Petroleum 2

Question 3.
What is petroleum? How does it occur? How is it mined?
Answer:
Petroleum.
It is dark coloured viscous, foul-smelling, oily liquid. It is a complex mixture of several solid, liquid, and gaseous hydrocarbons mixed with water, salt, and earth particles.

Occurrence of Petroleum.
Petroleum occurs deep down under the earth between two impervious rocks (non-porous rocks) as shown in Fig. Natural gas occurs above the petroleum oil trapped under rocks.

The crude petroleum is obtained by drilling a hole into the earth’s crust and sinking pipes into it. When the pipe reaches the oil deposit, natural gas comes out with great pressure. After the pressure has subsided, the crude oil is pumped out of the oil well. This process of obtaining crude oil from its sources is called mining.

7. Before the start of each dive, the referee or the official announcer shall announce in the language of the country the name of the competitor, and the type of dive he is going to execute.

8. The number of the dives to be performed and the manner of execution shall be displayed on an indicator board, visible’to both divers and judges. The dive to be executed shall not be announced until the diver has taken his position on the board or platform.

9. The dive shall be executed after the referee has given signal. If a competitor dives before the signal he shall repeat the dive.

10. Only listed dives shall be executed.

11. Each competitor shall deliver to the diving secretary four copies of a complete statement of the dives selected on an official form written in ink, or typewritten, not less than 24 hours before the date of each competition. This list should be in English or French language. If any other language is used, the competitor shall have to attach along with a translated version in English or French, for the accuracy of which he is entirely responsible in accordance with Rule 13.

The following details shall be given on this form:

Diving Game Rules - PSEB 10th Class Physical Education

Question 2.
What are the rules for the execution of the Dive?
Answer:
Rules for the Execution of the dive
Dives shall be executed on the following principles:

1. The starting position shall be free and unaffected. The approach to the starting position shall not be taken into consideration.

2. In the starting position, the competitor stands on the front end of the board or platform, with his body straight, head erect, arms straight and to the sides or above the head. The arm swing commences when the arms leave the starting position. If a competitor fails to assume the correct standing position, each judge shall deduct 1 to 3 points from his award.

The starting position of a running dive shall be assumed when the diver is ready to take the first step of the run. Forward take-off dives from the spring board may be performed either standing or running on the opinion of the diver. A prior declaration of the manner of take-off is not essential. The judge shall award points for a standing dive keeping in view the height and standard of execution.

3. The run should be smooth, straight and unhesitant. In a running dive from the spring board or platform the diver shall take at least four steps, including the take-off from one or both feet. If the diver takes less than four steps, one referee shall deduct two points from the award of each judge.

4. The take-off shall be bold, quite high and confident. In running dive, the take-off from the spring board shall be from both feet simultaneously, but from fixed boards the take-off may be from one foot only. While executing a standing dive, the diver shall not bounce on the board before the take-off.

While executing a running dive, the diver shall not be permitted to stop his run before the end of the board and to make more than one jump on the same spot before the final take-off. If a competitor, preparing for the take-off in backward dives, lifts his feet slightly off the board, it shall not be taken as a bounce but as an involuntary movement, but the judges may make a deduction from their awards according to individual opinion.

If in a dive, the diver touches the end of the board, or dives to the side of the direct line of flight, it indicates, no matter how well the dive may have been executed, that he was quite close to the heal’d for proper execution. Each judge shall decide about the deduction of awards according to his individual opinion.

If, in an Arm Stands Dive, a steady balance in the straight position is not shown, the judges shall deduct 1 to 3 points from the award. If the diver loses his balance of mind and reattempts the dive, he shall receive 2 points less. In case of a strong wind, the referee may give all divers the right to make a second attempt without deduction of points.

5. In all flying somersault dives, a straight position should be clearly shown for nearly half a somersault.

6. In straight dives with one half or full twist, the twisting should not manifestly be done from the board. In pike dives with twist, the twist must not be started until there has been a marked pike position. In somersault dives with twist, the twist may be performed at any time during the dive at the opinion of the diver.

Question 2.
How is the game of Table Tennis started?
Answer:
Order of Play. In Singles, a server does five services at a stretch whether he gets the score or not, thereafter the service passes on the other player. The other player also gets the right of doing five services. Thus, the service changes after every five services.

In Doubles, the server makes a goods service, then the receiver shall make a goods return. The partner of the server shall make a good service, thereafer, and the partner of the receiver, then, shall make a good return. Thus, turn by turn, each player shall make service and return in that order.

Good Service:
The server places the ball on the palm of his free hand, open and flat, with fingers pressed together and thumb free. Then he shall project the ball in the air and do the service in a manner that the ball remains visible to the judge. Then the ball shall be struck in a way that it touches the server’s court and passes directly over or around the net, and touches the receiver’s court.

In Doubles, the ball shall first touch the server’s right hand, right of court or the central line on the side of the net. Then the ball, passing over or around the net, touches the receiver’s right-half court, or the central line on his side of the net.

Good Return:
After having been served or returned in play, the ball shall be so struck as to pass directly over or around the net. It should touch directly the opponent’s court.

Ball in Play:
The ball is in play when it is projected from the hand for service. It shall be deemed to be in play until:

  • it has touched one court twice successively.
  • it has touched anything other than the net and supports.
  • it has been hit by a player more than one successively.
  • it has touched a player or anything he wears or carries.
  • in Doubles, it has touched the right half of the server or receiver.

A let:
A ball in play is called rally. A rally may be let if:

  • The served ball touches the net or its supports.
  • The service is delivered and the receiver is not yet ready.
  • A player fails to do good service or return owing to some accident.
  • The play is stopped for correction of the order of the game or the fault in ends.

Question 3.
How are points scored in the game of Table Tennis?
Answer:
Points:
A player shall lose a point in case:

  • he fails to deliver good service.
  • he fails to deliver good return when his opponent has made goods service or return.
  • he or his racket touches the net when the ball is in play.
  • his free hand touches the playing surface when the ball is in play.
  • he returns the ball with volley.
  • in Doubles, he strikes the ball out of turn.

Game:
A player or pair who scores first 21 points shall win the game. If both the players or pairs score 20 points, then that player or pair shall be the winner who scores 2 points before the other player or pair.

The Choice of Ends and Service

In the game of tennis, the choice of ends and the right to serve first shall be decided by toss. The toss winning player chooses to serve or not to serve first, and the other player chooses the right to end (side).

Change the Ends and Service

The change of ends and service shall be made in the following manner:

In the play, a player or pair who starts a game at one end shall be at the other end in the second game, and so on. This will continue till the end of the match. The ends change when any player or pair score first ten points in the last possible game in a match. In Singles, the service is changed after five points, which means that the server shall become receiver, and recevier shall become server.

In Doubles, the selected partner of the pair shall deliver the first service, and shall be received by the appropriate partner of the opposing pair. The receiver of the first five services shall deliver the second five services. The third five services shall be delivered by the partner of the first receiver. The fourth five services are delivered by the partner of the first receiver and received by the first server. The fifth five services are to be delivered like the first five, and so on. This order will continue till the end of the game.

Out of Order of Ends, Serving or Receiving

In case the players have not changed ends in time, they shall change the ends as soon as the mistake is detected provided the game is not completed. In case the game has been completed, all points scored shall be counted. If a player serves or receives out of turn, the play shall be stopped as soon as the error is detected. The game shall be started again by the server who was serving at the start of the game, or at the time when the score was 10. In such circumstances, the scores made before the error is detected shall be counted.

FeSO4 + Zn → ZnSO4 + Fe
On the basis of the above reactions, indicate which is the most reactive and which is the least reactive metal out of zinc, copper and iron ?
Answer:
In the first reaction, iron displaces copper from copper sulphate solution, therefore, iron is more reactive than copper. In the second reaction zinc displaces iron from iron sulphate, therefore, zinc is more reactive than iron. Therefore, zinc is the most reactive metal while copper is the least reactive.

Question 13.
Why are pickles, chutney and citrus fruits not stored in iron and aluminium utensils ?
Answer:
Certain foodstuffs, particularly citrus fruits, chutney, pickles and curd, which contain acids tend to attack kitchen utensils made of aluminium and iron forming poisonous salts. Iron and aluminium utensils are, therefore, not used to store pickles, chutney and citrus fruits.

Question 14.
What would you observe when a strip of zinc is dipped in the solution of copper sulphate ?
Answer:
Zinc being more reactive would replace copper from its salt solution i.e. copper sulphate.
Zn + CuSO4 → ZnSO4 + Cu

Question 15.
Can copper displace iron from iron sulphate solution ? Give reasons.
Answer:
No, because copper is less reactive than iron. As a result, it can’t replace iron from its salt solution i.e. iron sulphate. Only more reactive metals can replace less reactive metals from their salt solutions. Vice-versa is not possible i.e., less reactive metals cannot replace more reactive metals from their salt solutions.

Question 16.
Why does aluminium vassel lose its lusture after sometime ?

  2. It is not readily attacked by acids present in the food materials to be cooked.

Question 18.
What is corrosion ? What are the different ways to reduce corrosion ?
Answer:
Corrosion. Metals when exposed to moist air get covered with dull layer.
This layer can be easily removed giving place to the next such layer to be formed. In this way, metal is eaten up or corroded and the process is called corrosion.
Ways to reduce corrosion:

  1. By covering the metal with paint
  2. By applying oil or grease on the surface of metal.
  3. By coating the metal with some other metal which is not easily corroded by passing electricity.
  4. By making an alloy.

Question 19.
Sodium occurs in the combined state where as Gold in its native state, why ?
Answer:
Sodium is the most reactive metal. It readily combines with air and water to form its compounds. So it occurs as compound. On the other hand Gold is the noble metal and is not attacked by air, water or acids so it exists in its native form.

Question 20.
Does copper rust ? What will happen if copper is exposed to moist air ?

Question 4.
Write a paragraph in your own words on each of the following:
(a) Preparation of soil
(b) Sowing
(c) Weeding
(d) Threshing.
Answer:
(a) Preparation of Soil.
Soil is loosened and overturned to make it better ventilated and suitable for the growth of tiny organisms living in it. The entire process is called tillage and ploughing.

Soil if ploughed in dry season gets into big mud pieces or crumbs. These are broken down by plying a soil plank.
The ploughed soil is liable to be removed by wind and water. Wooden leveller is used to press the soil.

(b) Sowing.
The process of putting seeds in the soil is called sowing. It is the most important part of crop production. Before sowing, good quality of seeds are selected. The seeds are sown in the fields by hand (broadcasting) and by seed drill.

(c) Weeding.
It is a process of removal of unwanted plants i.e. weeds from the fields. It is necessary to remove the weeds since they compete with the main crop for water, nutrients, sunlight etc. The weeds may be removed manually by uprooting or cutting. The best time to remove them is before they produce flowers and seeds. It is done with a khurpi and a tractor driven harrow. Some chemicals called weedicides are used to control the weeds. They are sprayed in the fields for killing the weeds e.g. linazine, dalapon, etc.

(d) Threshing.
The separation of grains from the chaff in the harvested plants is called threshing. Animals are used on a large scale for threshing. In large farms, a machine called ‘thresher’ or a motorized machine called ‘combine’ are used for both harvesting and threshing.

Question 5.

Answer:
Differences between Manure and Fertilizers

Fertilizers Manure
1. These are mixtures of chemical compounds rich in nitrogen, phosphorus, potassium and manufactured in factories. 1. These are organic substances prepared from the decomposition of plant and animal wastes.
2. Chemical fertilizers are nutrients specific i.e. nitrogenous, phosphatic, etc. 2. They contain a mixture of various nutrients recycled from biomass wastes.
3. They are in a concentrated form. 3. They are not in a concentrated form.
4. They are easy to store or transport. 4. They are not easy to store or transport.
5. They are harmful if used in excess. 5. They are never harmful to the soil.

Question 6.
What is irrigation ? Describe two methods of irrigation which conserve water.
Answer:
Irrigation. Giving water to the fields at different intervals is called irrigation. The time and frequency of irrigation varies from crop to crop, soil to soil and season to season.

The latest irrigation methods help us to use water economically. The main methods used which conserve water are as follows:

1. Sprinkler System.
This system is more useful on the uneven lands where water is available in smaller quantity. The perpendicular pipes, having rotating nozzles on the top, are joined to the main pipe line at regular intervals. The water is allowed to flow through it with the help of a pump. The water escapes from the rotating nozzles. It is sprinkled on the crop as if it is raining. Sprinkler method is very useful for the sandy soil.

2. Drip System.
In this system, the water falls drop by drop just at the position of the roots. So it is called drip system.
Fig. Sprinkler System.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 1
It is the best technique of watering fruit plants, gardens and trees. Drip system consists of a main pipe to which lateral pipes are joined. The specially prepared nozzles are attached to these lateral pipes. It provides water to plants drop by drop. In this way, water is not wasted. So, it is a boon in regions where availability of water is poor.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 2

Question 7.
If wheat is sown in the Kharif season, what would happen ? Discuss.
Answer:
Wheat is a Rabi crop i.e. it is grown in winter season where there is low temperature and needs less water. So, if wheat is sown in Kharif season during rainy season, it gets more water which is harmful to the crop. The wheat crop droops down. It would not grow healthy.

PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management

Question 8.
Explain how soil gets affected by the continuous plantation of crops in a field.
Answer:
For the continuous plantation and better growth of crops, manure and fertilizers are added regularly in the field. Manure and fertilizers are the nutrients like nitrogen, phosphorus, potassium etc. They can change the nature of the soil. The soil may become more alkaline or acidic with addition of the nutrients.

Question 9.
What are weeds ? How can we control them ?
Answer:
Weeds. Weeds are undesirable plants that may grow naturally along with the crop. The removal of weeds is called weeding.

Methods to Control Weeds. Following methods are used to control the weeds:

  • Tilling. The process of loosening and turning of the soil is called tilling or ploughing. This is done by using plough. Tilling helps in uprooting and killing of weeds.
  • Manual Removal. This method includes the physical removal of weeds by uprooting or cutting them close to the ground. This is done with the help of Khurpa or Harrow.
  • Chemical Method. In this method weeds are controlled by using some chemicals, called weedicides like 2, 4-D. The weedicides are sprayed in the fields with a sprayer.

Question 3.
What are insecticides ?
Answer:
Insecticides.
The special chemicals which selectively kill the pests or harmful insects as well as their eggs and larvae, but do not affect the plants are called insecticides or pesticides.

Question 4.
Why should the harvested grains be protected from moisture ?
Answer:
Moisture and humidity promotes the growth of fungi or moulds on grains. Some of these microorganisms are poisonous also. So, it is very important to store harvested grains dry.

Question 5.
How does a farmer rotate crops in the fields ?
Answer:
Crop rotation involves the change of crop every year as alternate sowing of crops so that pathogen is killed in absence of suitable host.

Repeated growing of the same plant however may deplete the soil severely of specific nutrients. To prevent this it is advisable to cultivate two different types of plants alternately. For example, maize and wheat are grown alternately with groundnut. The groundnut plant, with its nitrogen fixing, bacteria enriches the soil with some nutrients, which are beneficial for wheat. Rotating different crops in this manner thus replenishes the soil naturally.

PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management

Question 6.
How are pests controlled in a crop field ?
Answer:
Pests are living organisms which cause diseases or kill or destroy the crop plants. In order to control the pests, pesticides such as Malathion, Disyston, B.H.C. etc. are used. They are sprayed on the crops. They kill the microbes without causing harm to plants and human beings who consume them.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 11

Question 7.
What are the harms of excess of water in the fields ?
Answer:
Harms of excess of water

  1. It can destroy crops.
  2. Continued water logging increases the amount of salt in the soil and can damage it permanently.
    Excess water can be drained off by providing a suitable outlet.

Question 8.
Why is it important to wash off fruits, grains or vegetables before being consumed ?
Answer:
It is important to wash off fruits, grains or vegetables because these when brought from fields to the market often have a coating of pesticides. Otherwise they prove to be harmful.

Question 9.
What is field fallow ? Why is it important ?
Answer:
Field Fallow.
Some fields are allowed to rest and regenerate for at least a season to support a crop. This is called field fallow.

Importance.
The growth of humus picks up which in turn promotes the growth of soil micro-organisms during such undisturbed periods. It leads to a rich replenishment of nutrients.

Question 10.
How are the stored grains damaged ?
Answer:
Rats and other rodents damage the stored grains. The amount of grain eaten by rats and rodents is estimated to be over 25% of the total produce.
Stored grains are also damaged by insects and worms. Such infested grains if consumed by people, cause many diseases.

Question 11.
What are weeds ? How are they removed ?
Answer:
Weeds. Weeds are undesirable plants that may grow naturally along with the crop. The removal of weeds is called weeding.

Methods to Control Weeds. Following methods are used to control the weeds:
1. Tilling. The process of loosening and turning of the soil is called tilling or ploughing. This is done by using plough. Tilling helps in uprooting and killing of weeds.
2. Manual Removal. This method includes the physical removal of weeds by uprooting or cutting them close to the ground. This is done with the help of Khurpa or Harrow.
3. Chemical Method. In this method weeds are controlled by using some chemicals, called weedicides like 2, 4-D. The weedicides are sprayed in the fields with a sprayer.

Question 13.
Why is ploughing of soil necessary before sowing seeds or crop plants ?
Answer:

  1. Ploughing tills the soil deeply. It may involve partial or complete turning over of soil.
  2. Ploughing clears land of the preceding crop and leaves the soil loosened.
  3. Repeated ploughing eliminates all weeds.
  4. Harmful insects are destroyed by ploughing.
  5. Ploughing makes the soil porous.
  6. Ploughing makes the soil soft, clean and suitable for sowing.

Question 14.
Why are fields manured ?
Answer:
Manuring of Fields.
Plants get their nutrients from the soil. If crops are grown continuously, they use all the nutrients present in the soil. To make up this deficiency of soil, manures are added to the soil.

Question 15.
What do you mean by harvesting and threshing ?
Answer:
Harvesting.
The cutting of the crop when it matures is called harvesting. Most of the crops are harvested with help of a sickle or huge combines.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 14

Threshing.
The separation of grains from the chaff is called threshing. Animals are used on a large scale for threshing.

Question 16.
What are the types of crops on the basis of seasons ? Give examples of each type.
Answer:
Crops are of two kinds on the basis of season:

  1. Kharif Crops. The crops which are grown during the monsoon season are called Kharif Crops.
    Examples. Maize, Bajra and Cotton etc.
  2. Rabi Crops. Those crops which are grown during the winter season are called Rabi Crops.
    Examples. Wheat, Gram and Mustard etc.
  3. Summer Crops. Those crops which are grown during summer seasons are called Summer Crops.
    Examples. Moong, Water melon, Cucumber, gourd etc.

Question 17.
What is mixed cropping ? Give an example.
Answer:
Mixed Cropping.
The practice of cultivating two crops simultaneously is done to economise the time and energy. This is called mixed cropping.
Example. The crop of groundnut is grown in the fields along with cotton.

Question 18.
Why is it necessary to sow seeds at an appropriate depth ?
Answer:
It is necessary to sow seeds at an appropriate depth because if the seeds are sown too deep, they will not be able to germinate. On the other hand, if they are sown at a shallow depth, then they will be eaten away by birds or animals.

Question 19.
How is the crop produce stored ?
Answer:
The crop produce is stored in godowns by agencies like Food Corporation of India and State Warehousing Corporations. Grains are sun dried before storing to reduce moisture contents of grains. This prevents the attack of pests. Large scale storing of grains is done in granaries and silos to protect grains from pests like rats and insects.

PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management

Question 20.
Define Fertilizer.
Answer:
Fertilizers.
These are the chemical substances that are man-made and are rich in nitrogen, phosphorus and potassium, i.e. they are rich in organic macronutrients which are needed by plants.

Question 21.
Why should we use organic manures ?
Answer:
We should use organic manure because it helps in replenishing the soil nutrients without causing any harm to the soil. This manure is considered much better than the fertilizers. Crops like vegetables and fruits grown by organic manure are considered safe as compared to the crops grown by using chemical fertilizers. Therefore, we should use organic manure in growing vegetables and fruits.

Question 22.
Some seeds are given to you to grow. What factors will you keep in mind ?
Answer:
We will keep the following factors in mind. These are:

  1. We would sow them at the correct depth.
  2. We would water them regularly and check the amount of water that we are putting.
  3. We would use manure at the proper time.
  4. We would ensure that no weeds grow with the plant.
  5. We would also spray pesticides.
  6. We would also ensure that the plant gets adequate sunlight.

Question 23.
Why should we discourage the use of chemical fertilizers ?
Answer:
Chemical fertilizers are harmful in the following ways thus the use of such fertilizers be discouraged:

  1. They damage the soil by reducing its natural recomposting ability.
  2. They change the chemical nature of soil.
  3. These chemicals are leached in the soil and are again absorbed by crop plants and enter food chain and damage the plants and animals.

Question 24.
How do we store grains ? What is cold storage ?
Answer:
Storage of Grains.

  1. Farmers make small boxes of metal or mud to store dried grains. These are called granaries.
  2. Dried grains are transferred to properly ventilated cemented halls. These cemented halls are called godowns.
  3. The storage of some fruits and vegetables at a low temperature is called cold storage.

Question 25.
What are the basic requirements for growing a crop in an area ?
Answer:
The basic requirements for growing a crop in an area are as follows:

  1. Proper type of soil
  2. Use of manures
  3. Irrigation
  4. Better varieties of seeds
  5. Agricultural tools
  6. Chemicals to prevent diseases of the plant crop.

Question 26.
Why all the crops do not grow in the same season ?
Answer:
All crops do not grow in the same season because every crop has its own specific requirements of soil and climatic conditions like light, temperature and air at the various stages of its growth and development.

Question 27.
Do all the crops have identical requirements of manures and fertilizers ?
Answer:
No, every crop has specific requirements of manures and fertilizers for growth and development of the plants. Farmyard manure is useful for paddy crops. The groundnut plants have nodulated roots. These nodulated roots contain nitrogen-fixing bacteria which convert the atmospheric nitrogen into the compounds of nitrites and nitrates. For the crop of wheat, farmyard manure and green manure of sunhemp plants are mixed in the soil.

Long Answer Type Questions

Question 1.
Explain the main agricultural practices.
Answer:
Main agricultural practices. The main agricultural practices are as follows:

1. Ploughing.
The process of loosening and turning the soil is called ploughing. This is done by using a plough. Ploughs are made of wood or iron. The ploughed land is then levelled so that the soil is not blown off by wind or drained off by water.

2. Sowing.
After the preparation of the soil, the seeds are sown in the fields by hand (broadcasting) or by seeds drill.

3. Irrigation.
Crop plants absorb water from the soil by roots. Water is essential for the growth of plants. Irrigation is done by various ways like lift irrigation, water wheel, swinging baskets, sprinklers and tubewells.

4. Manuring.
Every crop uses substantial amount of nutrients present in the soil. Soil is replenished with nutrients by adding manures to it.

5. Weeding.
Many unwanted plants also germinate and grow in the field. These plants compete with the crop for water, sunlight and nutrients. Therefore, it is necessary to remove these plants to get better crops. This is called weeding.

6. Protection of Crops.
Crops are spoiled by insects, fungi, bacteria and rodents etc. Chemicals like insecticides and weedicides are used to kill them.

7. Harvesting and Storage.
When the crop is ready, it is harvested at proper time. Crops are harvested by hand, using a sickle or by a harvester. The grains are separated from the chaff in the harvested plant. Then the grains are stored in big store houses. The amount of moisture in the grains should not be more than 14%.

Question 2.
What are the practices adopted to improve crop production ?
Answer:
The practices adopted to improve crop production are as follows:
1. Addition of fertilizers to the soil.
2. Selective breeding.
3. Weed control.
4. Control of plant diseases.

1. Fertilizers.
These are the chemical compounds which are added to the soil to increase the fertility. They make up for the deficiency of the required nutrients and help in increasing the crop production.

2. Selective Breeding.
Disease resistant seeds are produced by selective breeding. Regular use of high yield variety results in better crop production.

3. Weed Control.
The unwanted plants or weeds are controlled by using certain chemicals called weedicides.

4. Control of Plant Diseases.
Crops should be protected from insects, fungi, animals and other diseases. It is very useful practice for increasing crop production. Insects are very harmful to crops. So insecticides should be used to kill insects.

Question 3.
What are fertilizers ? What are mixed fertilizers ? Why do farmers add fertilizer to the soil ? How should we store fertilizers ?
Answer:
Fertilizers. Fertilizers are the chemical substances which maintain the fertility of soil.

Mixed Fertilizers. The fertilizers which supply many elements are known as mixed fertilizers.
Example.
1. NPK has nitrogen, phosphorus and potassium.
2. CAN is a mixed fertilizer of calcium, ammonium, nitrate.

Importance of Fertilizers.
The fertilizers and mixed fertilizers are added to the soil to make up for the deficiency for mineral elements like nitrogen, phosphorus and potassium. This deficiency is produced in the soil by growing the crops in succession. That is why farmers add fertilizers to the soil to improve crop-production.

Storing of Fertilizers.
Some fertilizers are moisture lover i.e. they are hygroscopic. If the fertilizers are stored in moist places, it is difficult to apply them in the fields. Some fertilizers spoil the bags in which they are stored. They should be stored in dry places.

Question 4.
Explain the various tools used for ploughing.
Answer:
Main tools used for ploughing. The tools used for ploughing are plough, hoe and cultivator.

1. Plough.
This is being used for tilling of soil, adding fertilizers to the crop, removing the weeds, scrapping of soil, etc. It is made of wood and drawn by a pair of bulls. It contains a strong triangular iron strip called ploughshare. The main part of the plough is a long log of wood which is called a plough shaft. There is a handle on one end. The other end is attached to a beam which is hung on the neck of bulls. One pair of bulls and a man can easily operate the plough.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 19

2. Hoe.
Hoe is a simple tool which is used for removing weeds and for loosening the soil. It has a long rod of wood or iron. A strong, broad and bent plate of iron is fixed to one of its ends and works like a blade. The other end of plough shaft is pulled by a pair of bulls.
PSEB 8th Class Science Solutions Chapter 1 Crop Production and Management 20

Short Answer Type Questions:

Question 1.
Rural Society.
Answer:
Rural society is that area where technology is scarcely used, primary relations are very important, small in size and where most of the population depends upon agriculture. In this way rural community is that community which lives at a definite place, which is small in size, which has very close relations in its members and primary relations exist in it. People know each other very well and the main occupation of the people is either agriculture or agriculture-related occupation.

PSEB 12th Class Sociology Important Questions Chapter 2 Rural Society

Question 2.
Two definitions of Rural Society.
Answer:
1. According to R.N. Mukherji, “A village is that community which is characterized by relative homogeneity, informality, prominence of primary groups, lesser density of population and agriculture as the main occupation.”

2. According to Peake, “The village community consists of a group of the related or unrelated persons larger than a single or unrelated persons, larger than a single family occupying a large house or a number of dwellings placed closed together, sometimes irregularly, sometimes in a street and cultivating originally in common a number of fields, dividing the available meadow land between them and pasturing their cattle upon surrounding waste land over which the community claims right as far as the boundaries of the adjacent community.”

Question 3.
Rural Society—Main occupation Agriculture.
Answer:
The main occupation of the tribal society is either agriculture or any of the related work because they are very much closely related with nature. Because they are closely related with nature, that’s why their views towards life are very much different. Yet many other occupations, like carpenter, blacksmith etc, are there in villages but they also make tools related with agriculture. Land is considered as a very important thing in tribal society and people like to live here because their life depends upon the land. Even the economic system and development of people and villages depend upon agriculture.

Question 4.
Rural Society—Scarcity of population and Homogeneity.
Answer:
Population of villages is very less as compared to urban areas. People are living in small groups and very much away from each other and these groups are known as villages. There are very less occupations in rural areas except agriculture because of which people like to go to cities to earn money and that’s why population in villages is very less. People have close relations with each other and their views are also same due to same occupation of agriculture. Customs, rituals, traditions etc. of rural people are common and there is hardly any. difference in their economic, moral and religious life. People in village are coming to live from far off places but they are the original inhabitants of villages or are living in the nearby areas. That? is why people have homogeneity among themselves.

Question 5.
Rural Society-Importance of Neighbourhood.-
Answer:
Neighbourhood has great importance in rural society. Main occupation of the people is agriculture in which they get enough pleasure time. This occupation hardly needs much time. That’s why people meet each other, talk with each other and co-operate with each other. People have very close relations with their neighbours. Neighbours generally are of same caste because of which their status is also same. People generally like to give respect to their neighbour. They come to help very quickly in each other’s problems. That’s why neighbourhood is of great importance in rural society.

Question 6.
Rural Family and Control of Family.
Answer:
Person is in complete control of the family in rural societies. Generally patriarchal families are there in the villages and every type of decision of the family is being taken by the head of the family. Division of labour in villages is being done on the basis of sex. Males are either doing agriculture or are going out of the house to earn some money and females are taking care of the house by living in the house. A joint family system is there in villages and a person adopts the traditional occupation of the family. Every member of the family works with each other and that’s why they have community feeling in them. Family is known as primary group. Younger ones like to give respect to elders. They have a great sense of co-operation due to same occupation. All the members of the family take part in all the festivals and religious activities. Person always takes the advice of the family before doing anything. In this way the family has complete control over its members.

Question 7.
Rural Society and closeness with Nature.
Answer:
Because the rural people live away from the artificial atmosphere, that’s why these people are very much close to nature. Their main occupation is agriculture and that’s why they are directly related with nature. Their life also depends upon nature. They worship Sun God, Varun, Indra etc. These people are very much afraid of natural forces like rain, flood, earthquake etc. because their agriculture depends upon these things. These forces can destroy their hard work of the whole year. That’s why these people are traditional and their outlook is also limited.

PSEB 12th Class Sociology Important Questions Chapter 2 Rural Society

Question 8.
Rural Society—Lower Status of Women.
Answer:
Status of women is very low in villages because females are limited only to household functions. The division of labor in villages in ancient time was based on sex. Females were doing household work and males were doing work out of the house. Yet the time is changing and people are sending their girls to schools but still their point of view towards women is the same.

Question 9.
Changes which are coming in Rural Society.
Answer:

  • Differences in urban and rural societies are decreasing.
  • Changes in the structure of agriculture and commercialization of agriculture.
  • Decreasing effect of religion.
  • Effect of technology has been increased.
  • Dependence on nature of farmers has been decreased.
  • Level of education is increasing.

Question 10.
Rural Society—Decreasing impact of Religion.
Answer:
Rural people were under great impact of religion in ancient times. Every type of agricultural activity was under the influence of religion but now this thing remains no more. In earlier times, trees, birds and animals were considered as sacred but now this has been reduced. Many changes have come in the religious beliefs, customs, traditions etc. of rural people. New generation hardly accepts these things. Daily life, in today’s technological age, is moving away from the influence of temples and gurudwaras.

Question 11.
Rural Family.
Or
Joint Family.
Answer:
Rural families are generally patriarchal and joint families. Father has the complete authority in rural family and all the members of rural family live in one house. Due to living in one house they make food in one kitchen and community feeling is too much. In this way joint families are there in rural societies in which members of many generations are living. These are large in size and every one has equal right over the property.

Question 12.
Rural Family—Patriarchal Family.
Or
More powers of father in Rural Family.

Every family gives dowry according to their economic status and according to the social status of the family of the bridegroom. If the economic status of the family is good then they give good dowry but if the economic status of the family is weak then they give less dowry. This custom is in great demand in modern times and it prevails equally in the whole of Indian society.

Question 21.
Rural Economy.
Answer:
The rural economy is based upon agriculture and agriculture is being done on land. That’s why land is of great importance in rural society and the rural economy. Around 70% population of our country is engaged in the occupation of either agriculture or any other agriculture-related occupation. Yet there are certain other occupations in the rural economy but agriculture is of great importance. People produce things by cultivating the land. Methods of production are still ancient. Yet farmers, in many parts of the country, are using modern technology and machines to do agriculture but still, most parts of the country are using old means of agriculture.

Question 22.
Indebtedness.
Answer:
Another important feature of the economy of Indian rural society is the indebtedness of farmers. There are many reasons behind the indebtedness of farmers. Rural families are large in size. Yet their income is less but their expenditure is more due to large family. They have to take loans on interest from money lenders to meet their needs because of which they come into the circle of indebtedness. Expenditure of agriculture has been increased to a great extent these days like rates of seeds and fertilizers have been increased, spending on diesel for pumps of irrigation due to unavailability of electricity. More expenditure on agriculture due to less rain, bad quality of production forces them to sell their produce at rates less than the minimum support price, etc. Due to these factors, farmers are unable to meet their expenditure on cultivation. That’s why they have to take loans either from banks or from money lenders. They are unable to repay their loans due to more rate of interest and slowly and slowly they come under the trap of indebtedness.

Question 23.
Jajmani System.
Answer:
The entire rural economy in the Jajmani system revolves around agriculture and farmer. Farmer has the most important place in rural economy and other castes have many related functions of agriculture. Farmer prepares the land for agriculture but other castes give their services for the completion of the whole agricultural process and they take their part from the produce of that land. The blacksmith makes the related tools of agriculture and cobler makes shoes for the farmer. The main feature of the Jajmani system is that human needs of life are fulfilled only at the local level. In this way rural economy moves in a proper way with the Jajmani system.

Long Answer Type Questions:

Question 1.
What is Rural Family? Explain its characteristics.
Answer:
Family keeps a very important place in rural social structure because family is of great importance in agriculturist societies. Generally, we can see many forms of families in villages but a joint family is that family which exists in all the rural societies. We can find Patriarchal joint families in every part of India. That’s why now we will discuss the joint family in rural society.

A joint family is a group in which members of many generations live with each other. It means that grand father-grand mother, mother-father, uncle-aunt, their children, wives of boys, and unmarried children live in one place.

According to Karve, “A joint family is a group of persons who generally live under one roof, who eat and cook at one hearth, who hold property in common and who participate in common worship and are related to each other as some particular type of kindred.”According to I.P. Desai, “We call that household joint family which has greater generation depth than the nuclear family and the members of which are related to one another by property, income and mutual rights and obligations.” So after looking at these definitions we can give some of the features of a joint family and these are :

  1. They are large in size.
  2. Members of this family have a sense of co-operation.
  3. Property in the family is common to all.
  4. All the members of the family live at one commonplace.
  5. All the economic, social, and cultural activities of the members are common in the family.

Desai was of the view that those societies, where occupations related to agriculture are more in number, have a patriarchal joint family. The joint family acts as an economic property in agricultural societies. Patriarchal rural joint family has many functional, psychological, political aspects which differentiate it from the urban family system. So from this description, it is clear that the generally patriarchal joint family exists in rural society. Characteristics of this type of family are given below : Characteristics of Rural Family

  1. Large in size
  2. Dependency upon agriculture
  3. More unity
  4. More inter-dependency and discipline
  5. More proudness of family
  6. More powers of the father
  7. More participation in household affairs.

Now we will explain them in detail.

1. Large in size: The first characteristic of rural family is that it is large in size because members of many generations live at one place. The increasing population of our country is responsible for its large size. Even at some places its members reach the number of 60-70. But generally one simple rural family has 6-15 members and that’s why it is large in size.

2. Dependency upon agriculture: The main occupation of the rural people is agriculture because of which all the members of rural family are engaged in agricultural activities. For example, ploughing is done by any one and any one else brings fodder for cattle. Females of the rural family work in fields because of which rural family is different from urban family. Many females give their help to the husbands in fields and work to fill the gap of labourer. Even females living at houses don’t have any leisure time. They give fodder and water to cattle. Their ideas, thinking etc. become the same because they work with each other in fields.

3. More unity: One of the important features of rural family is that it has more unity. Rural families have more unity as compared to urban families. Like husband- wife, grand father-grand son, parents have more emotional relations. If we look at the rural areas then we will come to know that rural people like to live in groups and their unity can be seen at the time of function of the family. All the members of rural family have same feelings, views, wishes, activities. They do same type of works and think in the same way. Importance of personal life is less as compared to the family. All the members live their fives according to the ideals and traditions of the family.

4. More inter-dependency and discipline: Members of rural family depend more upon each other as compared to urban families. Humans in urban areas fulfil their needs out of the family. But the economic, social, psychological, religious needs of humans are fulfilled only in the family. It is so because except family, no other means can fulfil human needs in villages and person alone cannot fulfil all of his needs. For example, no boy or girl in village can marry itself but family arranges for their marriage. Because of this more dependency family and elders have full control on their members. Younger members of the family never say no to elders for any work.

5. More proudness of family: Another important feature of the rural family is the more proudness of family. Because members of the family are interdependent and united that’s why family takes the form of a unit in which family has more importance than the member. In simple words family has more importance in rural areas than any individual member. Any work done by the member can become the proudness or black spot of the family. It is expected from every member of the family that he should maintain respect of the family. We can see example of proudness of the family that sometimes two families start fighting with each other for the respect of the family.

6. More powers of father: The father has more powers in rural family. Father is the wholly incharge of the family. Many functions of the family are there which are being done by father with his will, like division of labour on the basis of sex and age, marriage of chifdren, taking care of income and house etc. Father has so much influence on the family that not even a single member can speak against him. Rural family is exactly opposite to the urban family where every member of the family has its own importance.

7. More participation in household affairs: Another important feature of the rural family is that all the members of family greatly participate in household affairs. Members spend more time with each other due to same occupation and that’s why members of the family take part in every activity of the house: They work together in fields during day time and at home during night and that’s why they are very close to each other.

Except for these characteristics, rural families have many other characteristics like :

  1. Importance of religion
  2. Lower status of women
  3. Worship of ancestors
  4. Dominance of joint family

In this way many characteristics of rural family are given.

PSEB 12th Class Sociology Important Questions Chapter 2 Rural Society

Question 2.
What do you know about Rural Familism? Explain it.
Answer:
Family is a very important unit in the rural social structure. Every type of institution, which prevails in villages, is greatly influenced by rural family. That’s why family has more importance in rural society as compared to an individual. It is known as Familism. When the whole family is given importance as compared to one or two persons then it is known as familism. Some sociologists are of the view that in agriculturalist societies, social and political organizations has the features of the family because family is the basic and most important unit in rural society. Influence of familial traits over social organizations feel of rural society are made according to the and political organization is known as Familism.

According to Sorokin, “Because family is the basic social institution in rural society, that’s why it is naturally expected that feature of rural family and social institutions should have influence over agricultural groups. In other words it forms the basic social relations of all the rural familial relations. Word Familism is used for these social organizations.”
In this way when political and social institutions of the village are under the influence of religion then it is known as Familism. Familism has many features which are given below :

1. Family—in the form of an ideal. Family is considered as an ideal in the society. Family has some moral measurements, religious beliefs, social concept and if any one tries to break them or tries to destabilize the family then he is being criticised by others.

2. Family—a unit of social responsibility. Family is the basic unit of any rural society. That’s why it takes all the responsibilities and pays tax collectively. Any person in the village is known by his family. No one is known personally in the family.

3. Effect of family on political institutions. Forms of political institutions in agriculturalist societies are just like a rural family. Relation of ruler and general masses is just like as the relation of head of the family with other members of the family. Head of the family is the representative of the family in the political activities of the village. Even members give their vote to that party where head of the family says so.

4. Relations of co-operation. Relations in unban societies are not full of co-operation but are contractual. Person can disconnect his relation after the completion of his work. But relations in agriculturalist societies or in rural societies are not contractual but are full of co-operation, love and sympathy. Co-operative relations come forward due to living and working with each other by believing in same views and beliefs and with unity and integrity of the family.

5. Family—A unit of production, consumption and exchange. Economic system of rural society also has the features of rural family. Production and consumption is being done in the family. It means that production, in the family, is being done according to the needs of the family and family consumes that production. Exchange in villages is being done is a very simple way. People exchange things instead of exchange of money and things. Family is also the base of the exchange.

6. Many customs. All the process of rural life in agriculturalist societies moves around the customs of the family. Customs related to every aspect of life exists in rural society and they always affect every aspect of the life of the person.

7. Dominance of ancestral worship. Religion is of great importance in rural society. All the members of the family have to obey the customs and traditions of the family. Worship of ancestors is a very important part of rural society. People worship their ancestors with the worship of gods and godesses. In this way family has its own features in those societies where familism has its dominance.

Question 3.
What is Rural marriage? Explain its features.
Or
Explain the marriage system in rural society.
Answer:
Generally marriage is considered as necessary for every one because marriage is necessary for the continuation of the society. Children without marriage are not sanctioned by society and are considered as illegal. It is quite important in agricultural societies. Marriage of children is considered as necessary in rural society. Girl child is generally considered as burden on the parents. That’s why marriage of girl child is being done at very early age. In this way marriage is the relation between male and female whose aims are to make family, establish house, produce children and continuation of the society.

Marriage is the very important stage in human life. Indian society is basically a rural society because of which marriage is considered as a family affair. Two families make relations with each other with their help and boy and girl also make relations with each other. Marriage out of the clan and marriage within the caste is considered as necessary in rural society. We can come to know about the status of two families with marriage.

Marriage, in rural society, is not a contract but is instead considered as a religious sacrament. Marriage, in villages, is being done in traditional way and with complete > rituals and customs. Gods and Goddess are worshiped before marriage. Boy takes his Baraat to girls’ house and many rituals and customs are being performed related with marriage. With this marriage is completed. Yet these customs and rituals are decreasing in urban areas but rural societies used to perform marriage with all customs and rituals. We can’t see the great pomp and show of cities in rural marriage but it is being performed with complete traditions.

In this way whichever marriage, in rural society, is being performed with all , religious sacraments, customs, traditions etc. then it is known as rural marriage. With this marriage, not only religious customs are performed but the aims of marriage i.e. sexual satisfaction and procreation of children etc. are also fulfilled.

Characteristics of Rural Marriage:

1. Religious sacrament. Marriage is considered as a religious sacrament in rural society because its aim is religious. It has been written in religious books that person will do marriage to make his house, to produce children, for the continuation of society and to pay his debts. Person can pay his debts only by doing marriage and by producing children. Person in rural society has to go through many rituals from birth till death. That’s why it is considered as a religious sacrament.

2. Related with religion. Rural marriage is always related with religion because rural marriage is being performed with complete rituals and customs. Yet these religious rituals have been decreased to a great extent but they still exist in rural society. Person has to complete many religious rituals and that’s why he has to obey many duties like to pay many debts and to do many types of ‘yajnas’. It is necessary for a person to do marriage to do ‘yajnas’ because he cannot do yajna without marriage. In this way rural marriage is related with religion.

3. Marriage to be done with complete traditions. Marriage in rural society is performed after completing all the rituals and in a traditional way. Traditions, like boy goes to the girl’s house with Baraat, all the persons in Barat are dancing, after marriage boy takes the girl to his house in ‘Doli’ and then many religious customs are to be performed there with which marriage is performed. These traditions and customs not only exist in rural society but also prevail in Hindu marriage. That marriage is not considered as a complete marriage which is not performed with all the rituals and traditions.

4. Marriage cannot be broken. Marriage, in rural society, is not considered as a contract but is considered as a religious sacrament. If it is to be considered as a contract then it can be broken at any time like urban societies. But marriage is considered as a religious sacrament in rural society which cannot be broken at any time. Marriage is considered as a bond of seven births which cannot be broken.

5. Marriage is necessary. Marriage is considered necessary in rural society because unmarried children are considered as a burden on parents. It is necessary specially for girls because if the marriage of a girl is not performed then it is considered as the parents are unable to perform their duty. It has been believed in rural society that woman should bear a child and become a mother because it is necessary for the continuation of society. Marriage of girl is considered as necessary than that of boy because there is no fear of character losing of boy but if girl will go in a wrong direction then the status of the family will become lower.

6. Arranged marriage by parents. Marriage in rural societies is not a relation of one male and female but is considered as the relation of two families, groups or two villages. That’s why parents play an important role in finding mate for their children. Enough importance is given to the size, status, kinship and economic position of the family while selecting mate of the child. With this the personal traits of would be mate are also given enough importance. If the child has any personal problem then it would be very difficult to find his/her mate. Parents are doing marriage of their child and they always try to do marriage with great pomp and show.

7. Role of Priest. Brahmin or Priest has a tfery important role in marriage. Generally, in all societies, parents are matching the Janampatri (horoscope) of their children and this work is being done by astrologer. If Janampatri matches then they start the process of marriage but if Janampatri does not match then they stop the process at once. At the time of shagun, exchange of rings take place. In marriage he has a very important role to play because he performs the marriage after completing all the rituals of marriage. He reads many religious mantras to perform marriage. In this way religious person or priest has a very important role to play in marriage. With this one important thing is there in rural marriage and that is that boy and girl cannot meet each other during the time of mangni and marriage. Yet there is no restriction regarding this in urban areas. This short span of time is considered as very special because small things can create problems and marriage can also be broken.

Rules of Mate Selection:

Question 4.
Which types of rules are there in rural society regarding mate selection?
Answer:
The major question in front of parents, in any society, is to do marriage of their children. Mate is necessary for the marriage and selection of the mate is the biggest problem. Meaning of selection of mate is that finding life partner for their child. For selection of mate, it is necessary that the area of selection of marriage should be determined that where to do marriage and where not to do marriage. Some rules regarding selection of mate have been made in our societies that not to marry within clan or gotra but one has to marry within his caste or subcaste. Generally every society has its different rules and these rules are changing according to time and society. Selection of mate does not depend upon the wish of the person but is according to the rules made by society. That’s why selection of mate has been divided by Kapadia in three parts and these three parts are :

  1. The field of selection
  2. Parties for selection
  3. Criteria of selection.

Now we will explain them in detail.

1. Field of Selection. Some rules in Hindu society have been made regarding marriage like Endogamy and Exogamy. Field of .selection becomes limited after accepting and’ following these rules. Rules of endogamy and exogamy are given below :

1. Endogamy. According to the rules of Endogamy one needs to marry within his own caste. Caste was again divided into sub-castes. In this way man had to marry in sub-caste. During the times of caste system, this rule was strictly applied. If any one was trying to break or was breaking this rule then the -caste was throwing him out of caste and they were breaking or severing all types of relations with him. According to religious books society was divided into four castes. These castes were again divided into sub-castes. Every person has to marry in his own sub-caste. In this form of marriage many changes have come due to the passage of time. According to K.M. Kapadia, “The Hindu community is divided into a number of castes which are endogamous groups and in practice the caste is again divided into a number of sub-castes, each of which is further divided into sub-sections as visa and dasa in terms of locality.”

According to Hoebel, “Endogamy is a social rule which demands that a person should marry within a group of which he is a member.” There are different forms of endogamy available in India and these are given below :

  • Tribal Endogamy
  • Caste Endogamy
  • Class Endogamy
  • Sub-caste Endogamy
  • Racial Endogamy.

2. Exogamy. Institution of marriage is one of the important Social institutions. Any society cannot give permission to any couple to live as husband and wife without marriage. That’s why every society has made some rules to establish marriage in society. The most important function is the selection of the mate. Exogamy is also one of the rules of mate selection. In many societies the marital relations are forbidden between the persons who are related with each other by blood. According to Sumner, “Endogamy is conservative while exogamy is progressive.” In this way in exogamy marriage is prohibited within the group. Children of one parent are also forbidden to marry.

In Muslims marriage between the relatives of parents is permitted. In the Roman Catholic Church of England marriage with the sister-in-law, after the death of the wife, or Sororate marriage was not allowed. In Australia, boy can marry with the wife of his father if she is not his mother. According to the rule of Exogamy man is not permitted to marry in his caste, clan, Sapraver, Spinda etc. Some of its types are given below :

  • Gotra Exogamy.
  • Sapraver Exogamy
  • Spinda Exogamy
  • Village Exogamy
  • Totem Exogamy

2. Parties for Selection. It is right that societies have made different rules of selection of mate regarding marriage but other party to do marriage is also necessary. Many ways are there to find other party. The first way is that selection of other party should be done by the relatives of the boy or girl. They should fix the marriage after finding the boy or girl and after looking at their house etc. It is known as arranged marriage. Second way of finding other party is the selecting mate for marriage with the advice of their friends, relatives etc, This type of marriage prevails in higher class of Indian society. Third way is that boy and girl should find their mate themselves and marry with their respective choice: It is known as love marriage.

Relatives and friends play an important role in selection of mate regarding marriage. Parents, in rural areas, even ask their relatives and mediator for marriage so that they could find right match for their child. Brahmins also play an important role at this time because they move from one village to another and they know about the unmarried children of the village. Males of the family take the final decision. If any mediator finds the right match then he is generally rewarded by both the parties. Marriage in one’s own village is not allowed in rural society that’s why match is generally selected out of the clan, village and sparvar. This process is going on for a long time. The importance of mediator has been reduced in modern times and parents are finding themselves the mate of their child in far off places with the help of means of communication and transport.

Generally, parents fix the marriage of their children after asking them for their choice. These days children like to marry with their own choice because of which the trend of love marriages is increasing day by day. Inter caste marriages are also increasing due to love marriages.

3. Criteria of Selection. It is right that there are some rules regarding the selection of the mates and parties are also there. But there are some criteria to determine parties. These criteria are related with other party like family of other party, personal traits, dowry, etc. Their description is given below :

1) Family. In ancient times, more importance was given to the family for marriage instead of boy and girl. It was seen that whether family is fulfilling its religious duties or not. If family was completing its religious duties then that family was considered as good for the family unless it was not considered as fit for the marriage. Status of the family was also considered for the fixation of marriage.

Marriage, in rural society, is not considered as the relation between boy and girl but it is considered as the relation between two families, groups and two villages. Elders of the family play a very important role in fixation of the marriage. Choice of the boy and girl is given very less importance in marriage. Marriage is being done to fulfill social and religious responsibilities. Social status, economic status, size of the family, kinship of the other family are also kept in mind while selecting mate for marriage. With this also kept in mind that how much land other party has.

2) Individual abilities of the mate. Personal traits of the mate are also kept in mind with family while selecting mate for the child. Children, in rural societies, are also getting education these days and that’s why people also give enough importance to the personal traits of the mate. These traits are like character of the mate, age, household works, educational level, income, colour, physique, beauty, nature etc. If people want to find boy for their girl then it is also kept in mind that whether he is drug addict or not or what type of friend circle he has? If boy and girl are not beautiful, are black in colour, are handicapped etc. then very less chances are there of finding mate for them.

3) Dowry. People give dowry to their girl at the time of marriage and this process has been going on from the ancient times. At the time of marriage, parents are giving some gifts to the bridegroom and his relatives while sending their daughter to boy’s house. These gifts are known as dowry. Every family give dowry according to the their economic status and according to the social status of the family of bridegroom. If the economic status of the family is good then they give good dowry but if the economic status of the family is weak then they give less dowry.

This custom is in great demand in modern times and it prevails equally in whole of the Indian society. Yet, according to the Dowry Prohibition Act of 1961, giving and taking dowry is a punishable offence but still this process is going on in full swing. Selecuon of mate also becomes limited due to this process. It is so because every one wants to get more and more dowry and every one cannot give more dowry. That’s why around 6,000 girls every year die due to this. This custom also prevails in rural society. While selecting mate, it has been seen that which family can give how much dowry. In this way mate is selected on this given basis; Yet the importance of these rules is reduced due to many factors like increasing education, many laws made by government, effect of wasternization and intercaste marriages are increasing. But still these rules play an important role at the time of marriage.

PSEB 12th Class Sociology Important Questions Chapter 2 Rural Society

Question 5.
What do you know about Rural economy? Explain.
Or
Explain the characteristics of Rural economy.
Answer:
If we want to study rural society then first of all we have to understand rural economy because economic base of relations has a great importance in rural society. Land has been given a great importance in rural society because the main base of rural economy is land. 70% of the total population in India is engaged in agriculture or agriculture based occupations and agriculture is directly related with land. Land has direct influence on economic and social structure of rural society.

Because most of the Indian population is engaged in agricultural works, that’s why the economy of our country generally depends upon agriculture. Around half of the total income of the country comes from agriculture related functions. Yet there are many other occupations in villages but they are directly or indirectly related with agriculture. Many castes of a village give their services to many other castes and they get compensation of their service either in the form of money or their share in agriculture production. If people in villages do physical work then they are also related with agriculture like agricultural labourers. In this way we can see that generally most of the occupations in villages are related with agriculture. That’s why features of rural economy are related with either agriculture or land. Features of rural economy are given below :

1. Main Occupation-Agriculture. Main occupation of people of rural society is agriculture and agriculture is the main difference between rural economy and urban economy. The means and way of living for rural people is also agriculture. Ways of living, ideas, habits, thinking etc. of rural people ^Lso depend upon agriculture. The most important means of production in rural society is agriculture and land is considered as the base of social status. Animals, with land, are also considered as the property of the person. Many other occupations like carpenter, blacksmith* artists etc. are also the part of economy of rural society.

2. Production and Method of Production. Agricultural work, in the ancient times in rural societies, was being done with ploughs and oxen but agricultural work, in modern times, is being done with tractors, threshers, combines etc. Farmers grow many types of things like wheat, rice, maize, cotton, sunflower etc. Not only this, they also produce many types of vegetables and fruits. People are also engaged in many other related functions like piggery, poultry, dairy, fishing etc. Rivers, wells, tubewells etc. are being used for irrigation. Generally most of the farmers are used to plough their fields themselves but many farmers also give their land to other farmers on rent for agricultural functions. Production, before green revolution, from land was very less but it has been increased to a great extent after green revolution with the usage of new seeds and fertilizers. *Now farmers are using new seeds and chemical fertilizers to a great extent.

3. Ownership of Land. Many types of systems like Zamindari, Rayotwari, Mahalwari etc. were there in India in ancient times. According to these systems, farmers were only used to do agricultural work on land. They were not the owners of land. But systems were abolished after independence and farmers were made the owners of land. Now farmer is the owner and cultivator of the land. Big farmers are very less in number who have too much land. Marginal or small farmers are more in number who have small pieces of land. But this land is divided in the children of farmers. Many farmers have small pieces of land that they are unable to meet their demands with this much piece of land. That’s why government has started many programmes so as to improve their economic condition.

4. More Population. Rural societies have more population. Around two third part of population of our country lives in villages. Our country has second position in the world after China from the point of view of population. Because most of the people live in rural societies and depends upon agriculture that’s why economy of the country also depends upon agriculture. Half of the total income of our country comes from agriculture or from its related occupations. We hardly can see development in many parts of rural society due to more population.

5. Indebtedness. Another important feature of economy of Indian rural society is the indebtedness of farmers. There are many reasons behind indebtedness of farmers. Rural families are large in size. Yet their income is less but their expenditure is more due to large family. They have to take loan on interest from money lenders to meet their needs because of which they come in the circle of indebtedness. Expenditure of agriculture has been increased to a great extent these days like rates of seeds and fertilizers has been increased, spending on diesel for pumps of irrigation due to unavailability, of electricity. More expenditure on agriculture due to less rain, bad quality of production which forces them to sell their produce on rates less than the minimum support price etc.

Due to these factors farmers are unable to meet their expenditure on cultivation. That’s why they have to take loan either from banks or from money lenders. They are unable to repay their loans due to more rate of interest and slowly and slowly they come under the tjrap of indebtedness. In recent times, farmers are opting to do suicide in many areas of Maharashtra, Andhra Pradesh, Punjab, Haryana due to indebtedness. In this way indebtedness is a very important feature of rural economy.

6. Rural Industries. Another important aspect of rural economy is the availability of rural industries. These rural industries are small in size. Small industries, in ancient times, were- based on caste but rural industries, in modern times, are based on science and technology. Government is also encouraging people to establish small scale industries to give employment to the people Weaving of clothes, stitching, soap industry are some of the examples which are now the part and parcel of rural economy.

7. Production Relations. Institutional relations have a very specific place in agricultural production. Good relations can increase production and bad relations can decrease production. Yet, many changes are coming, in modern times, in institutional relations of agriculture, but still these relations have a great importance in Indian rural economy. Jajmani system is the most important among these relations.

Meaning of Jajman is that one who does service or who perform YAGYA’. With the passage of time, this word was started to be used for those people who accept services of other people. These ancestral relations of acceptance of service of giving service by different castes is known as Jajmani system. According to this system, generally priests, artisans and many other lower castes used to give their services to the people of higher castes, like any brahmin works as a priest for any specific caste, barber gives his service to that caste by cutting their hair and washerman washes their clothes. In this way all the members of that caste are the Jajmans of that brahmin, washerman and barber.

The whole rural economy in Jajmani system revolves around agriculture and farmer. Farmer has the most important place in rural economy and other castes have many related functions of agriculture. Farmer prepares the land for agriculture but other castes give their services for the completion of the whole agricultural process and they take their part from the produce of that land. Blacksmith makes the related tools of agriculture and cobler makes shoes for the farmer. The main feature of Jajmani system is that human needs of life are fulfilled only at the local level. In this way rural economy moves in a proper way with Jajmani system.

The relation of farmer and money lender also has a very important place in rural economy. If we look at the history then we will come to know that the Indian farmer is suppressed under the indebtedness of money lender right from the ancient times. Farmer needs money for many occasions like marriage, death, cultivation and this need is being fulfilled by money lender. It has been said that farmer takes birth under the indebtness of money lender, grows up and dies under it. In this way these relations are very important in rural economy.

Relations of farmer and labourer are also very important. In earlier times labourers used to work for their Jajmans under Jajmani system and farmers used to give some share of the product to these labourers. But now due to the decreasing effect of Jajmani system and increasing effect of money based economy it has brought many changes in these relations. Now contractual relations have come farward instead of Jajmani System. Rural economy also has a direct relationship with nature. If there is a good rain then production will be more but if less rain comes then production will also be less. Even science is unable to reduce the farmer’s dependency upon nature. In this way these relations have an important place in rural economy.

So after looking at these features we can conclude that the economy of rural society mainly depends upon agriculture and every type of relation of rural society is also related with agriculture.

Question 6.
What are the results of Indebtedness? How can we remove this problem?
Answer:
Results of Indebtedness. We can see many results of increasing indebtedness in many villages of India. Some of the results of ‘indebtedness’ are given below :

1. Slavery: The worst result of indebtedness can be seen in the increasing number of landless laborers. Moneylenders take advantage of the ignorance of illiteracy of helpless farmers and take away their land from them. In this way one farmer becomes a laborer and works as a laborer for money lender on his own land. Sometimes a person has to work for money lender to repay his debt and this position is not better than that of a servant. There is one tendency in some village that parents are sending their children to do work for money lenders to repay their loans were: Status of these children is just like slaves. In this way this problem of indebtedness has forced thousands of farmers to live a life of slavery.

2. Increase in Poverty: Another worst result of indebtedness can be seen in the increasing poverty because of which any person comes in the cycle of indebtedness. Then even with all of his efforts he cannot come out of that cycle and will remain poor for his whole life. It becomes very difficult for a person to repay his loan. Even sometimes grandson repays the loan of his grandfather.

3. Deterioration of Agriculture: Position of agriculture also deteriorates due to problem of indebtedness because farmer has to work for money lender on his own land. That’s why they hardly take care of agriculture which they were doing on their own land. Production also suffers with this and power of production of land also decreases with this.

4. Suicide: If any farmer comes under the cycle of indebtedness then he becomes weak day by day because he always remains in tension to repay his loan. Even some people try to do a lot of hard work but when they are unable to get the desired result then their mental condition becomes weak. In this way they commit suicide. Ways to Remove Indebtedness. Many suggestions have come forward to remove this problem and these suggestions are given below :

1. Governmental loan at low interest: Government should provide loans to farmers on a lower rate of interest so that they should be able to repay their loans at lower rate of interest. A system of small installments should be arranged for them to repay their governmental loans.

2. Co-operative societies and banks: Some cooperative societies and cooperative banks should be opened in villages to provide governmental loans at village level. With this farmers can get loans very easily and at very low rate of interest.

3. Arrangement for declaration of bankrupt: Sometimes the loan and interest on that loan become too much that it becomes impossible for the farmer to repay that loan with interest. That’s why arrangements should be made to declare him bankrupt and no one should take possession of his land and he should earn his bread .easily.

4. Laws for preventing dispossession of land: Government should make such laws that if any money lender tries to take possession of the land of the farmer then he should be prevented from doing this.

5. Control over the rate of interest. Money lenders take too much rate of interest from farmers. In some cases it becomes 5-10% per month. Government should fix the minimum and maximum rate of interest to be charged from farmers in villages. If any one tries to charge more then he should be strictly dealt.

6. Checking the accounts of the money lenders. Government should make some laws for money lenders to keep their records properly. These records and registers should be checked time to time. If any discrepancy would be found in the accounts then he should be punished. In this way we can keep a strict check on the problem of indebtedness to a great extent with these measures.

Question 7.
What do you know the concept of Panchayati Raj? Write in detail.
Answer:
There are two ways of developing local areas in our country. Local governments are there for the development of urban areas and panchayati raj institutions are there for the development of rural areas. Institutions of local government are based upon the concept of division of labour because functions here are divided in government and local groups. 70% of the population in our country lives in rural areas. The institution of local government which administers the rural areas is known as Panchayat. Panchayati Raj expresses only the institutional structure of rural area.

When British Empire was established in our country then the whole country was under the control of landlords and Zamindars. In 1935, Indian government passed a law which has given the complete sovereignity to states and the panchayati laws were given a new form. In Punjab, one Panchayat Act was passed in 1939 whose aim was to give some powers to the democratically elected institutions with which they would be able to work at a unit of local administration. On 2nd October 1961 the three-tier structure of Panchayati Raj was applied in the whole country. 73rd constitutional amendment was done in 1992 in which powers were decentralized upto the local level. With this the panchayati raj institutions were given many financial and other types of powers.

Many changes have taken place in Indian rural community during last 66 years. Most of the powers of Indian panchayats were taken away by Britishers. They wanted to run these panchayats according to their own way because of which they applied a new and common legal System in all the villages. Present panchayats are the result of the laws made after the independence.

1. According to A.S. Altekar, an authority on Indian polity, “The village panchayats in ancient India were responsible for various functions such as defence, collection of revenue, imposition of taxes, implementation of programme of public welfare and so on. They are very important institutions of decentralized administration.”

2. According to K. M. Panikar, “These Panchayats are the only permanent basis of ancient Indian history. These institutions have provided a solid base to the prosperity of the country.”

3. According to 4th part of Article 30 of the Constitution, “Organization of village Panchayats, the state shall take steps to organize panchayats, and endow them with such power and authority as may be necessary to enable them to function as units of self government.”
Village Panchayats are doing many functions for the development of villages and that’s why there are certain aims of panchayats and these aims are given below :

  • The first aim for the establishment of panchayats is to solve the problems of people at local level. These panchayats are finding solutions of problems and quarrels of the people.
  • Village Panchayats create the sense of cooperation, love and sympathy among the people so that every member of a village should contribute towards its progress.
  • Another aim of establishment of panchayats is to determine the members of panchayats for the smooth functioning of panchayats so that everyone should contribute towards the solution of the problems of the village. Function of public welfare is also completed with this.

Organization Of Village Panchayats:

There are two types of panchayats in the village. First type of panchayats which are elected according to the laws made by government and are formal in nature. Second type of panchayats are informal and they are known as caste panchayats. They don’t have any legal status but they play a very important role in keeping social control. Three types of organization of panchayats exist in our country and these are :

1. GRAM SABHA
All the adult persons of total population, of the village, are the members of Gram Sabha and it is the complete unit of the whole population of the village. This is the basic unit on which the whole structure of our democracy rests. Gram Sabha can be made in that village whose population is more than 250. If population of one village is less than 250 then two villages can jointly make the Gram Sabha. Every adult of the village is the member of Gram Sabha, who has the right to vote. There is one chairman and some members of every Gram Sabha. It is elected for 5 years. Functions of Gram Sabha. Gram Sabha approves the annual budget and the functions to be done for the development of the village and helps in applying these functions. It also helps in doing the functions of social welfare, programmes of adult education and of family’welfare. It also plays an important role in keeping unity in the village.

2. Village Panchayat Or Gram Panchayat

Every Gram Sabha elects one Gram Panchayat from its area. In this way Gram Sabha is an executive institution which elects members for Gram Panchayat. It has one Sarpanch and 5-13 panches. There are certain places in Panchayats which are reserved for backward classes and females. It is generally elected for 5 years but state government can dissolve them even before 5 years if it tries to misuse its powers. If any Gram Sabha is dissolved before completion of its term then all of its position will also come to an end. Village is generally divided in different parts to elect Panches and Gram Panchayat. Then the Panches and Sarpanch are elected by the members of Gram Sabha. One third of the total seats in Gram Panchayat are reserved for women and the seats are also reserved for backward classes according to the ratio of their population in that area. Any governmental official and mentally ill person cannot be elected for panchayat. Gram Panchayat works for the sanitation, recreation, development of industries and means of communication. It also solves the problems of the village.

Functions Of Panchayats:

Gram Panchayat does many functions for the village which are given below :

1. The first important function of Gram Panchayat is to raise the economic and social standard of the people. There are many social evils in villages. Panchayat motivates the people to remove those evils and tries to change their traditional point of view.

2. For allround development of any area, it is necessary that illiteracy should be eradicated from that area and it is the main reason of backwardness of Indian Society. Indian villages are also backward due to this reason. Panchayat tries to open schools in village and motivates the people to send their children in the school. It also arranges the adult education centre to teach the adults of the village.

3. Panchayat of a village also works for the welfare of the women and children of the village. It also arranges for giving education to females. The function of arrangement of good food and entertainment facilities is also of Panchayat.

4. There are no means of recreation in rural areas. That’s why Panchayat also arranges to provide recreational means in village. Panchayat arranges for. films, organizing fairs and the opening up of library in the village.

5. Increase in production is necessary in the agriculture based country. Panchayat tells the people about new techniques of agriculture, arranges for the new seeds and developed fertilizers for them so that their agricultural production could be increased.

6. It is very much necessary to establish small scale industries in villages for its allround development. That’s why Panchayat tries to establish small scale industries in villages with the help of governmental help. It helps in economic progress of the village and people get employment in their villages.

7. Means of irrigation are of great importance in good production of agriculture. Gram Panchayat arranges the wells and tubewells in Gram Panchayat. It also arranges for river water so that the people are able to irrigate their fields.

8. Generally people are fighting in villages. Panchayat tries to solve their problems in village.

9. Except these Panchayat also does many other functions like :

  • Function related to dairy, animal rearing, poultry.
  • Establishment of small scale industries.
  • Arrangement of means of transport and communication.
  • Arrangement of informal and formal education.
  • Arrangement of cultural activities etc.

Panchayati Raj Act was implemented in India on 21st April 1994. Three-tier structure of Panchayati Raj was implemented with this Act. This Act brought many changes in rural community. Village economy was also’improved with this. Panchayat does every type of function for welfare of village.

3. Nyaya Panchayat
The nature of two persons is not the same all the times. That’s why problems are arising among them. In this way problems between villagers are arising in and they fight with each other. Nyaya Panchayat stops and solves these problem. One Nyaya Panchayat is generally formed for 5-10 Gram Sabhas. Its members are elected and Sarpanch makes one Committee of 5 members. They have the right to ask questions to Panchayat.

4. Panchayat Samiti
Panchayats coming in one block are the members of Panchayat Samiti and Sarpanches of these Panchayats are the members of Panchayat Samiti. Members of Panchayat Samiti are also elected. Panchayat Samiti takes care of the functions of the Panchayats which are coming in its area. It checks the developmental functions of the village and directs the Panchayat for the welfare of the village. It is the second level of Panchayati Raj.

5. Zila Parishad
The highest level of Panchayati Raj is Zila Parishad which takes care of the functions of the Panchayats which are coming in the district. It is an executive institution. Chairman’s of Panchayat Samiti, elected members, members of Lok Sabha, Rajya Sabha and Legislative Assemblies are the members of Zila Parishad. All these take care of the developmental functions done in the villages of the district. Zila Parishad does many functions like improvement of agriculture, improvement of land, irrigation, rural electrification, arrangement of seeds and fertilizers, education, industries etc.

Question 8.
Explain the characteristics of Panchayati Raj according to 73rd Constitutional Amendment.
Answer:
73rd Constitutional Amendment was passed by Parliament in December 1992 and was sanctioned by President in April 1993. Panchayati Raj system was established through this constitutional amendment and its characteristics are given below :

1. There was no system of self-administration in Constitution for the local level before 73rd constitutional amendment. A new schedule and new part was added in Constitution through this Amendment. All the arrangements in this schedule and part are related with the Panchayati Raj system that which types of arrangements are there in this new system.

2. Definition of Gram Sabha is given in Constitution with this amendment according to which all the adults of the village, who have the right to vote, will be the members of Gram Sabha. State Legislative Assemblies can arrange Gram Sabha through law and can give them some functions. In this way Gram Sabha . will be established through a law passed by the State Legislative Assembly and it will determine its functions.

3. The definition of Panchayat is also given with the definition of Gram Sabha according to which Panchayat is an institution based on self rule which is established by state governments in rural areas.

4. One system in Constitution is established through this Constitutional amendment that the three-tier Panchayati Raj system will be established of self rule in rural areas. Panchayat will be at village level, Block Samiti at block level and the highest position will be of Zila Parishad at district level but state government can give them any other name.

5. This constitutional amendment says that the district will be divided at Panchayat level through this system and the members of Panchayat, Block Samiti and Zila Parishad will be directly elected by the people through the right of voting by adults of that area.

6. The responsibility of election at different levels, counting of votes and making of voters’ list will be of State Election Commission. This State Election Commission will be nominated by the Governor of that State. Its term, terms and conditions of ervice etc. will be determined according to the rules made by Governor. State Election Commission can be removed in that same way in which Judge of the high court is removed.

7. According to 73rd constitutional amendment the Sarpanch of the village Panchayat will be directly elected by the people.

8. Sarpanch of the village Panchayat can also be removed from his post even before the end of his term and the right of his removal is given to Gram Sabha. Gram Sabha can remove Sarpanch from his post if the Panchayat of that area gives its approval. There should be a majority behind this approval. For this one special meeting should be called and the presence of 50% members of Gram Sabha is necessary for this. If the Gram Sabha will pass the approval of removing Sarpanch from his post then the Sarpanch can be removed from his post.

9. In the same way members of Block Samiti and Zila Parishad will be elected by the people and their Chairman will be elected by the members themselves. Their Chairman can also be removed in that same way the Sarpanch can be removed. Chairman can be removed by two-thirds majority.

10. Some seats on these three tiers will be kept reserved.

  • Seats for Scheduled Castes and Tribes will be kept reserved in Panchayats. The number of reserved seats will be according to their ratio in the whole population.
  • One-third seats will be kept reserved for women.
  • One-third seats in Panchayats, Block Samitis and Zila Parishad will also be kept reserved. With this the l/3rd seats of Chairmen will also be kept reserved for women.

11. The term of these institutions is kept at 5 years. The term of any institution cannot exceed more than 5 years. If the state government comes to know about the misuse of powers by Panchayats then it can dissolve -it even before 5 years. But it should be elected again within 6 months. New elected Panchayat will complete the term of earlier Panchayat.

12. If any person cannot contest an election according to the law of state then he also cannot contest the election. But here is a difference in age. The age of 25 years is necessary to contest the election of state legislative assembly but the age of 21 years is fixed to contest the election of Panchayat.

13. Panchayats have been given some rights and duties according to the law of state legislative assembly. Panchayats have been given some rights to make and apply plans of economic development and social justice.

14. With this State Legislative Assembly can give them some powers to levy small taxes so that they can increase their income. With this state govt, will also give some share of the taxes, imposed by it, to these Panchayats. Grants will also be given as help for the development of the village.

In this way we can see that many important arrangements are kept by 73rd constitutional amendment through Panchayati Raj with which the importance of Panchayati Raj has been increased. Many steps have been taken to make this arrangement more effective.

Question 2.
What is traditional theory of caste origin?
Or
Write the traditional theory of caste origin.
Answer:
This theory is based on the writings of origin of caste in religious scriptures. According to the Purushsukta Shloka of Rigveda, Brahmins were born from the mouth of Brahma, Kshatriyas from arms, Vaishyas from legs and fourth varna was born from the feet of Brahma. The same thing also has been written in Vrihadayathak Upnishda. The same thing is written in Vrihadayathak Upnishda, Shantiparva of Mahabhartha and Manusmriti. In this way the origin of Varnas is considered as from Brahma. Critics of this view say in its opposition that Varna and caste are twb different concepts. Varna is based on Karma or function but the base of caste is birth. Actually Varna is the main base of caste which has taken the form of caste in its evolution. Question 3.

What do you understand by caste? Explain the difference between caste and varna.
Or
Explain caste as a form of social stratification.
Answer:
Caste System is one of the most important social institutions which is coming on from ancient times. It was one of the important bases of social stratification on the basis of which status and role of a person was determined in society. It has been believed that caste system was originated from Varna System. Person was free to adopt any one of the occupations in Varna system because he used to adopt that occupation which he had been able to do in a proper way. But later on rigidity of occupation came into being among humans and this rigidity was related to caste system.

Occupation of the person was related to his birth. Person had to adopt the occupation of that family in which he had taken birth. In this way Varna system was completely changed into caste system. Slowly and slowly caste system started to keep control over society in such a way that the life of the person was determined, right after his birth, that how he was to live his life. It has not only affected the social progress of our society but it also came into being as a social evil of the society. But if any one wants to get knowledge of Indian society then certainly he needs to take help of caste system.

Meaning of Caste System. The word ‘caste’ originated from the Portuguese word ‘Casta’ whose meaning is Race. It is also closely related with the Latin word ‘Castus’ which means Pure race. Actually, caste system is based upon birth. The caste in which the person takes birth, he needs to live with that caste only for the whole life. With the birth of the child, his ways of living life are determined. It keeps some restrictions on its members which are necessarily to be obeyed by the person.

This caste system was one of the main bases of Indian social system and all the aspects of Hindu social life were affected by this system. Its effect was so powerful that it affected every group and community living in India. Word caste has been taken from the Sanskrit word ‘Jana’ whose meaning is birth. Yet this system prevailed in other societies also but its developed form was available in India.

Definitions of Caste System:

To know the better meaning of Caste it is necessary for us to look at the definitions of Caste System given by different sociologists and psychologists.

  • According to Risley, “Caste is a collection of families or group of families bearing a common name, claiming a common descent from mythical ancestor, human or divine. Professing to follow the same hereditary calling and regarded by those who are competent to give an opinion as forming a single homogeneous community.”
  • According to Robert Bierstdt, “When a class system is a closed group on one or more than one issue then it is known as caste system.”
  • According to Blunt, “A caste is an endogamous group or collection of endogamous groups, bearing a common name, membership of which is hereditary, imposing on its members certain restrictions in the matter of social intercourse, either following a common traditional occupation or claiming a common origin and generally regarded as forming a single homogeneous community.”
  • According to Ketkar, “Caste is a social group having two characteristics:
  • Membership is confined to those who are born as members and includes all persons so bom.
  • The members are forbidden by a social law to marry outside the group.”
  • According to Martindale and Mona Chesi, “A caste is aggregate of persons whose share of obligations and privileges is fixed by birth, sanctioned and supported by magic and religion.

Difference Between Varna and Caste:

Question 2.
Traditional and Occuptional theories of caste origin do not explain the total facts of its origin. How?
Answer:
Actually there are many other theories about the origin of caste system except traditional and occupational theories. That’s why these both theories of caste origin do not explain the total picture of caste origin. The complete explanation of all these theories is given below:

  • Traditional Theory
  • Racial Theory
  • Geographical Theory
  • Occupational Theory
  • Evolutionary Theory
  • Religious Theory
  • Mana Theory

The description of these theories is given below:

1. Traditional Theory. Traditional theory related to the origin of caste system is written in Hindu religious books. The most ancient explanation in Vedic literature about caste system is based upon one Mantra of‘Purush Sakta’ of ‘Rigveda’. According to this Mantra all the four Varna’s were originated from the different parts of the body of Brahma. Brahmins were originated from the mouth of Brahma, Kshatriyas ^.from arms, Vaishya’s from legs and lower castes were originated from the feet of Brahma. In Manu Smriti, Manu has also given the functions of all four Varnas. Brahmin will give education because he came from mouth, Kshatriya will use weapons and will protect the people because he came from arms. Vaishya will do the work of business, agriculture and rearing animals. In the end lower caste people will serve the higher three Varnas because they came from the feet of Brahma.

In ‘Mahabhartha’ it is also written that how different castes and sub castes were originated. In Vedic age there was no existence of Pratiloma marriage, only Anuloma marriages were there. Because Pratiloma marriage was not sanctioned by society that is why the children produced by this marriage were not given any Varna and they were differentiated from Hindu society. Later on they became lower castes and sub-castes.

But this traditional theory has been criticised because the explanation of Varna System is there in this theory but there is no name of caste system in it and caste and Varna both are different from each other. Critics also disagree upon the fact that all the castes and sub castes were originated due to Anuloma and Pratiloma type of marriage. While criticisng Manu, many scholars say that the division of castes was not originated due to Varna system. If it could have happened then the number of sub-castes would have been lesser than that of main castes but it is actually opposite to it.

2. Racial Theory. Many scholars have given the racial theory about the origin of caste system. According to Risley, Maclever, Weber, Crober etc. racial element is very important in the origin of caste system. Ghurye, Dutt and Majumdar also gave support to it. According to Risley three factors are responsible for the origin of caste system—(i) Racial exchange (ii) Interrelation due to exchange and (Hi) Sense of class difference.

Caste system in India was started after the arrival of Indo-Aryan people. The society of this race was’divided in 4 parts and they also applied this concept on India after their arrival to India First of all Aryans had defeated the original inhabitants of India and then they had established one sided marital relations with them because females in Aryans were less in number. From here the custom of Anuloma marriage was started. Pratiloma marriage was not given sanction because Aryans refused to marry their daughters with Indian people. When the’ needs of Aryans were fulfilled then they stopped the custom of Anuloma marriage. Racial mixture was increased due to Anuloma marriage and different castes ceyne into being.

According to Ghurye, Aryan people had given themselves higher status than original inhabitants of India. They started the policy of living away from original inhabitants to maintain racial purity. They kept themselves, in higher three varnas and had given the status of slave or shudra to the original people of India. With the passage of time society was divided in the groups of higher or lower status. That is why, according to Ghurye, caste system is the contribution of Brahmins and Aryan Culture.

Majumdar was of the view that cultural conflict and racial exchange has originated the groups of higher and lower status in India. Many reasons were there of racial mixture like less number of females in India, developed Dravidian culture, their matrilineal system, worship of gods and goddesses, wish to live life at one place, different customs etc. After the conquest of Aryan people over Dravidian people mutual exchange and cultural conflict was started among them. That is why many social groups came into being who became endogamous. From here the status of every group or caste was determined according to the racial purity and on the basis of living away from other groups.
Racial theory has been criticised because it has explained about the restrictions of marital relations but has not explained about the rules of feeding. Muslims and Christians are unable to take the form of a caste, even they have cultural differences. In this way caste system came into being because of many reasons, not because one reason.

3. Geographical Theory. Gilbart gave the geographical theory about the origin of caste system. According to him caste system came into being due to living of different groups in different parts of the country. This view is also given in Tamil Literature. This view can be explained on the basis of many examples. For example Brahmins living near to the bank of Sarswati river were known as ‘Sarswat Brahmins’ and people living in Kannouj were known as Kannoujias. In this way names of many other castes were kept on the basis of their living place. But this theory has been criticised by most of the scholars because many castes exist in one geographical area and the names of all these castes are not related with that geographical area.

4. Occupational Theory. Nesfield and Dahlman gave the occupational theory about the origin of caste system. According to Nesfield, different castes were originated on the basis of different occupations and he completely disagrees with racial factors. Racial mixture was at its advanced level even before the origin of caste system. According to him caste system has not been originated due to religion because religion cannot give that fundamentalist base which is necessary for caste system. In this way, according to Nesfield, only occupation is responsible for the origin of caste system.

According to Dahlman earlier Indian Society was divided in three parts-priests, King or ruler and Botirgouisee. Occupations of all the three classes were related with religious, political and economic activities. Then with the passage of time these groups were divided into small-small groups on the basis of occupation and relations. Earlier they had taken the form of business enterprises and then were changed into business federals. Later on these federals were developed into castes.

This theory has also been criticised. It is not correct to tell the direct relation between religion and caste. This theory is away from racial theory because there is some racial difference between higher and lower groups. With this if caste system was originated from business enterprises then why it originated only in India and not in any other country. This theory is unable to give answers of these questions.

5. Evolutionary Theory. This theory was given by Denzil Ibbetson. According to him, caste system was not originated on the basis of four varnas but was originated by the organizations which were formed on economic basis. According to him, earlier people lived like wanderers and there was no existence of caste system. Blood relations were there among people and there was no feeling of higher or lower among them. But slowly and slowly and by living with each other economic development was started and people started to do agricultural work. With the passage of time economic life became complex and a need was felt of divison of labour.

It became the duty of the king to make such a policy which could be based on division of labour and occupational differences. With this many new classes came into being. Community feeling was developed due to living with each other. With time these groups had made their unions to secure their interests. Every union had adopted the policy of endogamy to save its occupational secrets. In this way due to endogamy caste system came into being. Slowly and slowly these groups had made their place in social hierarchy.

This theory has also been criticised because unions on the basis of occupations are available in all the societies. Then why the caste system developed in India. Economic factor can be taken as one of the factors of origin but cannot be taken as the alone factor.

6. The Religious Theory. This theory was given by Hokart and Senart. According to Hokart, caste system’s origin and division of Indian society was happened due to religious customs and theories. In ancient Indian society religion was very important and any animal was also sacrificed to gods. In the custom of sacrifice, reading of mantras and worship was also involved in which many persons were required. Slowly and slowly people, who were doing religious work, were organized and it took the form of caste system. According to Hokart, occupation of every caste goes on from generation to generation. The main base of occupation is not economic but was religious.

According to Senart, restrictions related to feeding came due to religious factors and people were divided into castes and sub-castes. But some sociologists are of the view that caste system is a not a religious institution but is a social institution. That is why this theory is not correct. Caste system is very complex and this theory related to its origin is very simple which is not correct.

7. Mana Theory. Hutton was of the view that the elements of caste system were there in India even before the arrival of the Aryans in India. When Aryans came to India then they strengthened these elements to secure their interests. Social divison in India was not very much clear before them but the Aryans had differentiated it and kept themselves at the top of the system. According to Hutton, this was at an early stage. It had accepted the restrictions of Caste System and clarified it with the help of Taboo. In ancient times, Mana was considered as invisible divine force which exists in every person and can move from one person to another just by touching each other. Tribal people believe that difference among humans is because of Mana power. People stay away from foreigners because they are afraid of Mana. Even they never touch those people in their tribe, which are considered as evils. In this way tribe keeps some restrictions on its members on some things which are known as Taboo.

According to Hutton, even Hindu, Muslim, Parsis and Buddhist people also believe in Mana and Taboo. Discrimination related to Mana and Taboo were there even before the Aryans came to India. That is why restrictions among different groups related to marriage, feeding, occupation etc. were there: When caste system was started then it kept many restrictions over its members.

This theory has also been criticised by scholars. They say that yet Mana and Taboo also exist in tribes of other countries of the world but we cannot find caste system anywhere else. With this the culture of tribes never represents the whole Indian culture. Hutton has also not given any proof on the basis of which one can accept that Mana and Taboo were there in pre-Aryans period.

Question 3.
Identify those changes which raise the possibility of India as casteless society.
Answer:
1. End to the Discrimination and Untouchability. In 1955, Indian government passed a law ‘Untouchability Offence Act’ and tried to eradicate untouchability. Now if any one says ‘Untouchable’ to any person of lower caste then he will be considered as criminal. Government adopted the policy of reservation in government institutions to uplift the lower castes. On the basis of this policy, special provision is kept to give jobs to lower caste people. In modern times person of every caste is doing every type of work. Government gave scholarships to the people of backward classes so that they should be able to get any status in society with some hard work. In this way the discrimination of untouchability has been reduced to a great extent.

2. Change in Caste Hierarchy. The hierarchy which was determind by the caste system in Indian society, has been changed completely. Lower castes have been uplifted in society by a number of processes like urbanization, industrialization, sanskritization etc. In modern times, no caste considers inferior itself than the other castes. Even people of higher castes are ready to marry in the lower castes. Some want to obtain the facilities given to lower castes by the government and some want to marry in them after looking at their richness. In this way social mobility came into being in Indian society and now we cannot find the hierarchy of castes anywhere.

3. Changes in Restrictions of Food and Drink. In ancient times, feeding of the caste was determined by the caste. Food was divided into two parts and feeding relations of a caste were pre-determined. But in modern times it was very difficult to adopt these restrictions. When people of different c&stes came in contact with each other in cities then these restrictions slowly and slowly came to an end. Cooks in hotels belong to different castes and people eat jp hotels by sitting with each other and without asking each other’s caste. In cities people work with each other and that is why they started to eat with each other. In this way a number of changes came in the feeding restrictions of a caste. ,

4. Decline in the Status of Brahmins. Changes in caste system were started even under the rule of Britishers on Indian society. First of all British government started to behave equally with all .the people of different castes. According to them all of them are IndiAnswer: They started to give western education to Indian people instead of religious education. Every one was free to get education in these educational institutions. In this way there was no question of superiority of brahmins because humans started to attain social status according to their ability and not on the basis of their caste.

Lower castes have taken their status upwards by doing progress in economic sector. After Independence, Indian government tried to remove the superiority of upper castes by making some laws. Now every one can get higher status in society by getting higher education. In this way the importance of the birth of the person has come to an end. Importance of money has reduced the superiority of upper castes. Now one rich person gets more respect and prestige in society.

5. Freedom in Selection of Occupation. In ancient Indian society, occupation of person was determined right after his birth and it was according to his caste. Person had to adopt the occupation of his caste, even against his wish. He was not allowed to adopt any other occupation except his pre-determined occupation. But because of many reasons, society started to give importance to personal ability. Now humans are free to adopt occupation of their choice. It means that person can select the occupation according to his ability. Even the concept of profit has been tied with this. No occupation is higher or lower in their eyes. Now they adopt that occupation in which they see more profit. In this way the freedom, which person has got in selection of occupation, has brought changes in caste system.

6. Change in Status of Woman. Status of woman was not good under the influence of caste system. She used to spend her life only by living in the four walls of the house. She was neither free to get education nor she was free to speak on any subject. In this way she had to spend her life in a suppressed way. But in modern times, she has got freedom in all sectors of life and she is now no more under the control of males. Now she is economically self-dependent. Status of females has been completely changed. Now people feel happy in case of birth of a baby child. Now there is no difference in boy or girl child. Even government has given reservation to females for their upliftment. Now every female is free to marry anywhere she wants. Even her parents are not interfering in her decisions.

7. Change in the Marriage System. During the ancient times, caste system has made many tough rules related to marriage. No one was free to marry out of his sub-caste. But in modern times people have started to work with each other with which they come closer to each other. Inter caste marriage got sanctions of society. Now person can marry anywhere with his wish.

Second change which came in the sector of marriage is that earlier child marriage was very popular. Widow had to live as a widow for the whole life and she was not allowed to remarry. But government has banned child marriage and has set the age for mariage i.e. 18 years for girl and 21 years for boy. Widow -remarriage was also given sanction by society and governments.

Question 4.
Mention those examples which reveal that caste is still a dominant system of Indian society.
Answer:
Caste system is an integral part of Indian society from ancient times. Even in today’s modern age, caste system exists in Indian rural society. But when we are talking about the interface of caste then two things generally come in front of us.

  • Caste system is changing
  • Caste is restrengthening

Now we will see them one by one.

1. Is caste system being replaced by class system? Many scholars are of the view that after looking at the changes coming in caste system we can say that caste is changing in class. According to them, because of modernization, urbanization, westernization, industrialization etc. many changes have taken place in the structure of the caste. Importance of birth has been decreased and the feature of caste related to occupation has been changed. Now one caste has been changed into many classes and persons of different castes are taking form of one class. Caste is adopting the features of class. For example many trade unions have been made in factories which protect the interests of labourers.

Members of these trade unions belong to different castes. They come together because their occupation is same, class consciousness comes in them and they fight collectively to meet their demands. People from lower castes collectively are making their organization. At one time caste system was a closed group but now it is opening up like class. This situation comes in industries as well as in agricultural sector. Because of industrialization household rural industries and traditional occupations have been destroyed because of which people are doing agriculture. Farmers who don’t have land are doing labour. Indian government has passed a number of laws. They have been given a number of economic, political and social rights.

Reservation is given to the people of lower castes in every section. They have been given political rights and all the castes are collectively forming a class. Many changes are coming in castes. That’s why caste is getting features of class. In this way on the basis of given description we can say that caste is getting features of class and is taking the form of class. In this way caste is changing.

2. Caste is restrengthening. Yet many scholars are of the view that caste is changing into class and reasons are given above. But many scholars are also of the view that caste is not changing but is restrengthening. We cannot say that really the caste is changing. Base of caste is social and the base of class is economic. These scholars are of the view that because of number of changes are there in their nature and form, that is why they are strengthening. They are giving following reasons for that:

  • Members of one caste are using modern means of communication, press to spread their message to the other members of caste.
  • Educational institutions based upon caste have been opened up which are
    propagating in the favour of their own caste and which give support to their candidates in elections.
  • During elections, selection of the candidate is being done on the basis of population of any particular caste. Candidate is generally selected from the most populated caste that city.
  • Different castes are joining hands with each other, while keeping in mind their interests, so that their interests could be secured.
  • Many political parties based on caste came into existence.
  • Even today people are choosing boy or girl of their own caste to marry. Number of intercaste marriages are very less.
  • Government has given reservation to different castes in jobs and in educational institutions. That is why hatredness between different castes is increasing and caste consciousness is increasing day by day.
  •  Caste consciousness is increasing because of facilities given to different castes about jobs and education. After looking at this we can say that yet many changes are coming in caste and it is changing in caste but still it exists quite firmly in rural society. Our democratic system has also given strength to it due to reservations.
