General Instructions Direction for the following 6 (six) items: Read the following five passages and answer the items (1-6) that follow, Your answers to these items should be based on the passages only. Passage - 1 In India, over the last decade or so, labour has been departing agriculture, but is only going to construction and unregistered manufacturing which are not markedly better jobs. Services, where labour tends to be most productive, are not generating the additional jobs the country needs. India will need 24 million or so jobs over the next decade. The new sector, e-commerce, can at best close only half the jobs gap. Only those sectors that drive domestic demand, such as health and education can comfortably fill the other half. 1. Which one of the following is best implied in the passage?

  1. A.Strong measures need to be taken to reduce the rural to urban migration of labour.
  2. B.The working condition in construction and unregistered manufacturing needs to be improved.
  3. C.Service sector has been reducing the problem of unemployment.
  4. D.Increased social sector spending is imperative for large-scale job creation.

Explanation

The main aim of the author in the passage is to discuss the problem of unemployment in India. These are the problems facing India currently and they can increase in the next decade. He is not only concerned about the jobs but also the quality of the jobs. He also tries to give the possible solutions for this problem. He starts the passage by highlighting that the labour force from agricultural activities is shifting to other sectors like manufacturing and construction. He has not mentioned that this shift is from rural areas to urban areas. Hence, option (a) is incorrect in the context. The author has mentioned that unregistered manufacturing and construction employers might not be good paymasters. So, statement (b) can be an apt assumption that there is some exploitation of labours in these unorganized sectors, and there is a need for their upliftment. But it is not an implied fact. It is only an assumption. Based on this rationale, option (b) can also be avoided. It is mentioned that the Services are also failing to create sufficient jobs as they were doing in the recent past. Statement in option (c) contradicts the facts given in the passage. The author emphasises that to create good job opportunities on a large scale, domestic demand shall boost up. It is implied here that the domestic demand is linked with the social sectors like health and education. Hence, option (d) is the most appropriate answer to the question.

Passage - 2 In India the current focus on the right to privacy is based on some new realities of the digital age. A right is a substantive right only if it works in all situations, and for everyone. A right to free expression for an individual about her exploitation, for instance, is meaningless without actual availability of security that guarantees that private force cannot be used to thwart this right. The role of the State, therefore, is not just to abstain from preventing rightful free expression, but also to actively ensure that private parties are not able to block it. On the basis of the above passage, the following assumptions have been made: UPSC CIVIL SERVICES EXAMINATION (PRELIMS)-CSAT 1. State should have some institutions to ensure its appropriate role in a digital society. 2. State should ensure that private parties do not violate the citizens’ right to privacy. 3. Digital economy is not compatible with the idea of not violating the citizens’ privacy. Which of the above assumptions is/are valid?

  1. A.1 and 2
  2. B.3 only
  3. C.1 and 3
  4. D.2 only

Explanation

The passage primarily makes two points. The first point is that the right to free expression in a digitally connected society can be exercised only in a fear-free environment and the second point is that this feeling of security shall be ensured by the state. It is a logical assumption that the state would require some systematic instruments to achieve the objective of ensuring safety. Hence, Statement 1 is logical and rational. While statement 1 gives the requirement of the institutions for ensuring the safety of citizens to express themselves freely, Statement 2 explains the duty of these institutions. So, statement 1 and statement 2 are interlinked. These are correct assumptions based on the contents of the passage. Statement 3 is irrelevant and farfetched as it does not find support in the passage. It can be ignored. Option (a) gives the right combination of correct assumptions.

Passage - 3 One of the biggest ironies around water is that it comes from rivers and other wetlands. Yet it is seen as divorced from them. While water is used as a resource, public policy does not always grasp that it is a part of the natural ecosystem. Efforts at engineering water systems are thus efforts at augmenting water supply rather than strengthening the capacities of ecological systems. Which one of the following is the most logical and rational inference that can be made from the above passage?

  1. A.Rivers and other wetlands should be protected under Ramsar Convention.
  2. B.Engineering water systems should be modernized and further augmented.
  3. C.Wetlands need to be reinforced as more than just open sources of water.
  4. D.Water supply should not be free of cost so as to prevent its misuse or overuse.

Explanation

The author highlights that the problem of water shortage lies in the shrinking natural water resources. Local water resources are not divorced from their natural ecosystems. But the policymakers, mistakenly, try to engineer the water systems to improve the water supply. Option (a) is incorrect as it mentions Ramasar Convention which is not mentioned in the passage. It might be true that Ramasar Convention is linked with saving natural water resources but we have to answer the question only based on information provided in the passage. Option (b) is not the intent of the author in the passage. So, it cannot be a correct inference based on the reading of the passage. Option (c) is the correct inference as the local water resources are inherently linked with their original water resources. Option (d) is a farfetched judgement and is out of context as it does not find relevance in the passage.

CSAT (Aptitude)

Passage - 4 Asset allocation is the most important investment decision we will ever make, and sadly, most of us do not give that decision the importance it deserves. We are adamant about seeking predictability with our future. We tend to think of investing in risky assets as extremely volatile and value eroding. We also dislike fluctuating returns and the loss of control of investment. We think our money is best left idle, unproductive but safe. There is no asset that is risk-free. We could lose our jobs, our homes can loss value, our banks can go bankrupt, our bonds can default, the government can collapse and companies we chose fondly may cease to exist. But we cannot live life assuming that all these extreme events are waiting to happen, and all at the same time. All these extreme forms of risks we know will not manifest at the same time. Which one of the following statements best implies the suggestion given by the author of the passage?

  1. A.Distribute your wealth across different kinds of assets so that your risks would be minimized.
  2. B.Risk-taking behaviour should be a necessary component of your personality if you want to generate wealth.
  3. C.While making investments, find a trustworthy asset management organi- zation which would manage your wealth for you.
  4. D.You should know that investing your money is a risky business.

Explanation

An implication is a conclusion that can be drawn from something although it is not explicitly stated. In the passage, the author suggests we invest in distribution way. In that way your wealth is divided across different kinds of assets so that your risks would be minimized. He has not mentioned specifically how to invest, he only says- ‘leave your fear and invest’, he does not suggest anything beyond that. Hence, option (b) and (c) are incorrect. Option (d) is in contradiction with the facts presented in the passage. Hence, it can be outrightly rejected as a potential implication. Only option (b) is in coherence with the content of the passage.

CSAT (Aptitude)

Passage - 5 Although most of the Genetically Modified (GM) crops cultivated now are genetically engineered for a single trait, in future, crops genetically engineered for more than one trait will be the norm. Thus, biotechnology’s role in agriculture and the regulation of the same cannot be understood solely in the context of the current generation of GM crops. Instead, there is a need to take a comprehensive look, taking into account various aspects, including socio-economic impacts, so that the potential of the technology can be harnessed while minimizing negative impacts. Given the importance of biotechnology in developing varieties that can help in climate change mitigation and adaptation, not using biotechnology as a part of the climate change action plan cannot be an option. Domestic regulation of biotechnology cannot be viewed in isolation of trade policy and obligations under various international treaties and conventions. With reference to the above passage, the following assumptions have been made: 1. Biotechnology regulation is an evolving process. 2. Participation of people is needed in policy decisions regarding biotechnology regulation. 3. Biotechnology regulation should take into account socio-economic aspects in decision-making. 4. Wider involvement of political executive in biotechnology regulation improves its effectiveness in dealing with the country’s trade policies and international obligations. Which of the above assumptions are valid?

  1. A.1, 2 and 4 only
  2. B.1 and 3 only
  3. C.2, 3 and 4 only
  4. D.1, 2, 3 and 4

Explanation

The passage strongly put that the role of biotechnology is not limited to Genetically modified crops only. It has a comprehensive role in reducing climate change and also in other socio-economic fields. The author points out that the domestic regulations on biotechnology is an evolving process. Hence, the crux of the passage sees biotechnology as having a wider role than current use in GM crops only. Options (a) and (c) are incorrect as it is not mentioned in the passage. Option (b) is right. Option (d) gives irrelevant information and is out of context.
