UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 1

Directions for the following 6 (six) items:

Read the following two passages and Solution: the items that follow each passage. Your Solutions to these items should be based on the passages only.

Passage I


The poor especially in market economics need the strength that collectivities offer for creating more economic, social and political space for themselves, for enhancing their socio-economic well-being and voice, and as a protection against free market individualism. It has been argued that a group approach to farming, especially in the form of bottom up agricultural production collectivities, offers substantial scope for poverty alleviation and empowering the poor as well as enhancing agricultural productivity. To realize this potential, however, the groups would need to be voluntary in nature, small in size, participative in decision making and equitable in work sharing and benefit distribution. There are many notable examples of such collectivities to be found in varied contexts, such as in transitions economies. All of them bear witness to the possibility of successful cooperation under given conditions. And although the gender impact of the family cooperatives in the transition economies are uncertain, the Indian examples of women-only groups farming offer considerable potential for benefiting women.

 

 


Q. Agricultural collectivities such as group based farming can provide the rural poor

1. Empowerment

2. Increased agricultural productivity.

3. Safeguard against exploitative markets.

4. Surplus production of agricultural commodities.

Select the correct Solution: using the codes given below:

Solution: b) The word “imperative” is an extreme word. It means something which is absolutely necessary. The passage only says that they are helpful.

UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 4

Passage II

 

In a typical Western liberal context, deepening of democracy invariably leads to consolidation of ‘liberal values’. In the Indian context, democratization is translated into greater involvement of people not as ‘individuals’ which is a staple to liberal discourse, but as communities or groups. Individuals are getting involved in the public sphere not as ‘atomized’ individuals but as members of primordial communities drawn on religious or caste identity. Community-identity seems to be the governing force. It is not therefore surprising that the so-called peripheral groups continue to maintain their identities with reference to the social groups {caste, religion or sex} to which they belong while getting involved in the political processes despite the fact that their political goals remain more or less identical. By helping to articulate the political voice of the marginalized, democracy in India has led to ‘a loosening of social strictures’ and empowered the peripherals to be confident of their ability to improve the socio economic conditions in which they are placed. This is a significant political process that had led to a silent revolution through a meaningful transfer of power from the upper caste cities to various subaltern groups within the democratic framework of public governance.

 

 

Q. According to the passage, what does “deepening of democracy” mean in the Western context?

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 4

Solution: d) Option (a) talks about the Indian context. Option (b) talks about democracy in general.Option (c) talks about the consequences of democratization in a normal society. In the Western context it simply means people embrace liberal values. So, none of the statements are correct.A careful reading of passage will give you the solutions.

Q. Greater democratization in India has not necessarily led to

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 5

Solution: b) Option (a) could have been true; but its very general – it talks about public sphere; and not Indian politics in specific.So, lesson is: Keep a check on general and over-arching statements.

Q. What is the “silent revolution” that has occurred in the Indian democratic process?

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 6

Solution: c) Option (a) is incorrect, which also makes option (d) incorrect.Option (b) is incorrect, because the loosening has not been in the voting behaviour; it has been towards the social structures and participation in the political process.If you see this line “– ‘loosening of social strictures’ and empowered the peripherals to be confident of their ability to improve the socio economic conditions in which they are placed. This is a significant political process that had led to a silent revolution”, you will understand the solution.

Directions for the following 15 (fifteen) items:

Read the following three passages and solve the items that follow each passage. Your Solutions to these items should be based on the passages only.

Passage I


Education, without a doubt, has an important functional, instrumental and utilitarian dimension. This is revealed when one asks questions such as 'what is the purpose of education?'. The Solutions, too often, are 'to acquire qualifications for employment/upward mobility', 'wider/higher (in terms of income) opportunities', and 'to meet the needs for trained human power in diverse field for national development'. But in its deepest sense education is not instrumentalist. That is to say, it is not to be justified outside of itself because it leads to the acquisition of formal skills or of certain desired psychological – social attributes. It must be respected in itself. Education is thus not a commodity to be acquired or possessed and then used, but a process of inestimable importance to individuals and society, although it can and does have enormous use value. Education then, is a process of expansion and conversion, not in the sense of conversion turning students into doctors or engineers, but the widening and turning out of the mind – the creation, sustenance and development of self-critical awareness and independence of thought. It is an inner process of moral-intellectual development.

Q. What do you understand by the 'instrumentalist' view of education?

Passage II


Chemical pesticides lose their role in sustainable agriculture if the pests evolve resistance. The evolution of the pesticide resistance is simply natural selection in action. It is almost certain to occur when vast numbers of a genetically variable population are killed. One or a few individuals may be unusually resistant (perhaps because they possess an enzyme that can detoxify the pesticide). If the pesticide is applied repeatedly, each successive generation of the pest will contain a larger proportion of resistant individuals. Pests typically have a high intrinsic rate of reproduction, and so a few individuals in one generation may give rise to hundreds or thousands in the next, and resistance spreads very rapidly in a population.

This problem was often ignored in the past, even though the first case of DDT (dichlorodiphenyltrichloroethane) resistance was reported as early as 1946. There is an exponential increase in the numbers of invertebrates that have evolved resistance and in the number pesticides against which resistance has evolved. Resistance has been recorded in every family of arthropod pests (including dipterans such as mosquitoes and house flies, as well as beetles, moths, wasps, fleas, lice and mites) as well as in weeds and plant pathogens. Take the Alabama leaf worm, a moth pest of cotton, as an example. It has developed resistance in one or more regions of the world to aldrin, DDT, dieldrin, endrin, lindane and toxaphene.

If chemical pesticides brought nothing but problems, - if their use was intrinsically and acutely unsustainable – then they would already have fallen out of widespread use. This has not happened. Instead, their rate of production has increased rapidly. The ratio of cost to benefit for the individual agricultural producer has remained in favour of pesticide use. In the USA, insecticides have been estimated to benefit the agricultural products to the tune of around $5 for every $1 spent.
Moreover, in many poorer countries, the prospect of imminent mass starvation, or of an epidemic disease, are so frightening that the social and health costs of using pesticides have to be ignored. In general the use of pesticides is justified by objective measures such as 'lives saved', 'economic efficiency of food production' and 'total food produced'. In these very fundamental senses, their use may be described as sustainable. In practice, sustainability depends on continually developing new pesticides that keep at least one step ahead of the pests – pesticides that are less persistent, biodegradable and more accurately targeted at the pests.

Q. “The evolution of pesticide resistance is natural selection in action.” What does it actually imply?  

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 19

Solution: c) Option (a) and (b) are incorrect as they are nowhere mentioned in the passage.Option (c) is correct because it follows the logic of evolution and natural selection.

Instead, their rate of production has increased rapidly. The ratio of cost to benefit for the individual agricultural producer has remained in favour of pesticide use. In the USA, insecticides have been estimated to benefit the agricultural products to the tune of around $5 for every $1 spent.
Moreover, in many poorer countries, the prospect of imminent mass starvation, or of an epidemic disease, are so frightening that the social and health costs of using pesticides have to be ignored. In general the use of pesticides is justified by objective measures such as 'lives saved', 'economic efficiency of food production' and 'total food produced'. In these very fundamental senses, their use may be described as sustainable. In practice, sustainability depends on continually developing new pesticides that keep at least one step ahead of the pests – pesticides that are less persistent, biodegradable and more accurately targeted at the pests.

 

 

 

Q. How do pesticides act as agents for the selection of resistant individuals in any pest population?

1. It is possible that in a pest population the individuals will behave differently due to their genetic makeup.

2. Pests do possess the ability to detoxify the pesticides.

3. Evolution of pesticide resistance is equally distributed in pest population.

Which of the statements given above is/are correct?

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 22

Solution: a) Statement 1 has been mentioned clearly in the passage and is the very base on which the whole passage stands. Others are not mentioned.

UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 23

Passage II


Chemical pesticides lose their role in sustainable agriculture if the pests evolve resistance. The evolution of the pesticide resistance is simply natural selection in action. It is almost certain to occur when vast numbers of a genetically variable population are killed. One or a few individuals may be unusually resistant (perhaps because they possess an enzyme that can detoxify the pesticide). If the pesticide is applied repeatedly, each successive generation of the pest will contain a larger proportion of resistant individuals. Pests typically have a high intrinsic rate of reproduction, and so a few individuals in one generation may give rise to hundreds or thousands in the next, and resistance spreads very rapidly in a population.

This problem was often ignored in the past, even though the first case of DDT (dichlorodiphenyltrichloroethane) resistance was reported as early as 1946. There is an exponential increase in the numbers of invertebrates that have evolved resistance and in the number pesticides against which resistance has evolved. Resistance has been recorded in every family of arthropod pests (including dipterans such as mosquitoes and house flies, as well as beetles, moths, wasps, fleas, lice and mites) as well as in weeds and plant pathogens. Take the Alabama leaf worm, a moth pest of cotton, as an example. It has developed resistance in one or more regions of the world to aldrin, DDT, dieldrin, endrin, lindane and toxaphene.

If chemical pesticides brought nothing but problems, - if their use was intrinsically and acutely unsustainable – then they would already have fallen out of widespread use. This has not happened. Instead, their rate of production has increased rapidly. The ratio of cost to benefit for the individual agricultural producer has remained in favour of pesticide use.

In these very fundamental senses, their use may be described as sustainable. In practice, sustainability depends on continually developing new pesticides that keep at least one step ahead of the pests – pesticides that are less persistent, biodegradable and more accurately targeted at the pests.

 

 

Q. Why is the use of chemical pesticides generally justified by giving the examples of poor and developing countries?

1. Developed countries can afford to do away with use of pesticides by adapting to organic farming, but it is imperative for poor and developing countries to use chemical pesticides.

2. In poor and developing countries, the pesticide addresses the problem of epidemic diseases of crops and eases the food problem.

3. The social and health costs of pesticide use are generally ignored in poor and developing countries.

Which of the statements given above is/are correct?

Detailed Solution for UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 23

Solution: c) You might feel why is statement 3 wrong? Because it mentions both poor and developing countries have to ignore the costs. In the passage, its only poor countries that ignore the cost. 

Moreover, statement 1’s first part is out of context generalizations. Lesson: Read the statements very carefully and keep cross checking for minute differences with the passage.

UPSC Prelims Past Year Paper 2012: Paper 2 (CSAT) - Question 25

Passage III


Today's developing economies use much less energy per capita than developed countries such as the United State did at similar incomes, showing the potential for lower-carbon growth. Adaptation and mitigation need to be integrated into a climate-smart development strategy that increases resilience, reduces the threat of further global warming, and improves development outcomes. Adaptation and mitigation measures can advance development, and prosperity can raise incomes and foster better institutions. A healthier population living in better – built houses and with access to bank loans and social security is better equipped to deal with a changing climate and its consequences. Advancing robust, resilient development policies that promote adaptation is needed today because changes is the climate, already begun, will increase even in the short term.
The spread of economic prosperity has always been intertwined with adaptation to changing ecological conditions. But as growth has altered the environment and as environmental change has accelerated, sustaining growth and adaptability demands greater capacity to understand our environment, generate new adaptive technologies and practices, and diffuse them widely. As economic historians have explained, much of humankind's creative potential has directed at adapting to the changing world. But adaptation cannot cope with all the impacts related to climate change, especially as larger changes unfold in the long term.
Countries cannot grow out of harm's way fast enough to match the changing climate. And some growth strategies, whether driven by the government or the market, can also add to vulnerability – particularly if they over exploit natural resources. Under the Soviet development plan, irrigated cotton cultivation expanded in water-stressed Central Asia and led to the near disappearance of the Aral Sea, threatening the livelihoods of fishermen, herders and farmers. And clearing mangroves- the natural coastal buffers against storm surges – to make way for intensive farming or housing development, increases the physical vulnerability of coastal settlements, whether in Guinea or in Louisiana.

 

 

Q.  Which of the following conditions of growth can add to vulnerability?

1. When the growth occurs due to excessive exploitation of mineral resources and forests

2. When the growth brings about a change in humankind's creative potential.

3. When the growth is envisaged only for providing houses and social security to the people.

4. When the growth occurs due to emphasis on farming only.
