Directions for the following 6 (six) items:

Read the following five passages and answer items that follow. Your answers to these items should be based on the Passages only.

Paaaage-1

Bank credit to the industrial sector has started shrinking. Its decline has been a serious concern as credit growth is essential to revive investment. The problem's Origins lie in the incomplete reforms of the last 25 years. An institutional change that should have followed the 1991 reforms should have been setting up of a resolution corporation for banks. In a market economy with booms and busts, banks should be allowed to be set up and to fail. Today, we cannot shut down banks because there is no proper system to shut them down. Weak loss-making banks continue to need more capital.

61. Which one of the following is the most logical and rational inference that can be made from the above passage?

(a) Indian banking system is not able to help the country in its economic growth.

(b) Economic reforms that started in 1991 have not helped in improving the economy to expected levels.

(c) India lacks the institutional mechanism to deal with the failure of banks.

(d) Encouraging the foreign investments in our industrial sector is a good alternative to this sector's dependence on banks for credit.

Answer:(c)

Passage-2

India has tremendous potential for solar energy. We all realize that we have to stop burning fossil fuels to meet our energy needs. But certain renewable resources are still going through their cost Curves and learning curves to get the required amount of output. The Indian Government has strongly committed to its targets of reducing emissions by 33 percent by 2030, and towards this it has initiated a strong push towards a gas-based economy and has also invested heavily in renewable energy. However, business houses are wary of investing too heavily in renewable energy at a time when the technology is not yet ready.

62. Which one of the following is the most logical and rational inference that can be made from the above passage?

(a) India's commitment to reduce emissions by 33% is unlikely to be achieved.

(b) India should import gas rather than invest in renewable resources.

(c) Getting renewable resources to market too soon may be costly.

(d) India should put in more efforts in the exploration of natural gas.

Answer:(c)

63. With reference to the above passage, the following assumptions have been made:

1. Governments often provide inefficient and costly subsidies for technologies that may not be ready in the near future.
2. India’s commitment of reducing emissions by 33% by 2030 shall be on the basis of gas-based economy.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Answer:(d)

Passage-3

Genome editing is different from genome modification. Genome editing typically involves finding the part of a plant genome that could be changed to render it less vulnerable to disease, or resistant to certain herbicides, or to increase yields. Researchers use ‘molecular scissors’ to dissect the genome and repair it, Which is a process that occurs naturally when plants are under attack from diseases and can throw up new mutations that enable the plant to survive future attacks. This evolutionary process can effectively be speeded up now that it is possible to examine plant genomes in detail in laboratories, and create mechanisms through which the relevant genes can be altered very precisely.

64. With reference to the above passage, the following assumptions have been made:

1. Genome editing does not require the transfer of genes from one plant to another.
2. Through genome editing, the chosen genes can be altered precisely in a manner akin to the natural process that helps plants to adapt to the environmental factors.

Which of the above assumptions is/are valid?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Answer:(c) 

Passage-4

Many people understand the connection n solid waste management and health in terms of the consequences of unattended heaps of garbage which become home for flies and other Vermin. However, there is another aspect that is not well-understood, that is, what happens when unscientific solid waste management combines with poor drainage and dumping of untreated sewage into drains which are meant to carry storm water during rains. The result is choked drains which are full of stagnant water breeding mosquitoes, resulting in the spread of water-borne diseases.

65. In the context of India, which one of the following statements best reflects the eritical message of the passage?

(a) In India, the drainage networks are not separate for sewerage and storm water.

(b) Urban local bodies do not have enough resources and legislative authority to deal with the problems or waste management.

(c) Solid waste management should be integrated with the maintenance of drainage and sewerage networks.

(d) Bad management of solid waste and sewerage systems by our municipalities is the reason for drinking water shortages in our cities.

Passage-1

Spanish ships in the late 16th century first brought the potato tuber from South America to Europe whereby in the early 19th century, it bad become a reliable backup to cereal crops, particularly in the cold, rain-soaked soils of Ireland. The Irish were soon almost wholly dependent on the potato as their staple food. And they were planting primarily one prodigious variety, the ‘Lumper' potato, whose genetic frailty would be cruelly exposed by the fungus 'Phytophthora infestans’. In 1845, spores of the deadly fungus began spreading across the country, destroying nearly all the Lumpers in its path. The resulting famine killed or displaced millions.

41. Which one or the following statements best reflects the critical message or the passage?

(a) For introducing any foreign plant into a country, the soil and climate conditions of that country should be suitable.

(b) As a staple food of a country, tuber crops like potato cannot replace cereal crops.

(c) Some or the fungal infections or plants cannot be prevented or stopped from spreading across large areas.

(d) Relying on a homogeneous food source is not desirable.

Passage-2

India is at once among the fastest growing global economies and home to the largest number of malnourished children in the world. There are regions where malnutrition is not the exception but the norm. And across the country, malnutrition is the cause of death for roughly half the 1-3 million children who die before their fifth birthday each year. Even those children who survive suffer permanently from the damage that has already been done to their bodies and minds from not getting enough of the right foods and nutrients. Around 44 million children under 5 are stunted. That makes it harder for them to learn in school and subsequently earn a living as adults. Their lifetime earnings potential is almost a quarter less than that or their healthy peers.

42. With reference to the above passage, which of the following is/are the most rational and practical implication/ Implications?

1. India’s Public Distribution System should be monitored by the Union Government.

Passage—3

The pulse variety ‘Pusa Arhar 16’ has the potential to be grown in the paddy-growing of Punjab, Haryana and Uttar Pradesh and eventually in all of India. Its yield (about 2000 kg/hectare) will be significantly greater than those of the existing varieties and because its size will be uniform, it will be amenable to mechanical harvesting, an attractive feature for farmers in northern India who currently use this technology for paddy. Most important, Arhar straw, unlike paddy straw, is green arid can be ploughed back into the soil. In Paddy straw, the problem is the high silica content, which does not allow for easy decomposition. In the case of Arhar, the farmer, even after combine harvesting, just needs to run a rotovator to cut the leftover straw into pieces, which can be ploughed back and will decompose very fast. AU this is difficult with leftover paddy stalks that cannot be easily salvaged or ploughed back. Farmers, therefore, choose the easiest option of simply burning it.

43. Which of the following are the most rational inferences that can be made from the passage?

 Passage-5

In India, agriculture still engages about half of workforce, and about 85 per cent of its farms mall and marginal. Compared to China Vietnam, which have experienced fast structural and rural transformation, India's story is of slow transformation. As a result, poverty reduction in India was at a much slower pace during 1988—2014, compared to China and Vietnam. India's poverty reduction was slow during 1988-2005, but during 2005-2012, it accelerated dramatically—almost three times faster than during the earlier period. What did India do during this period? Research reveals that the relative price scenario changed significantly (by more than 50%) in favour of agriculture in the wake of rising global prices. This boosted private investments in agriculture by more than 5o%. As a result, agri-GDP growth touched 4/1% during 2007-2012 as against 2.4% during 2002—2007. The net surplus or agri-trade touched $25 billion in 2013-2014: real farm wages rose by 7% per annum. All this led to unprecedented fall in poverty.

26. With reference to the above passage, the following assumptions have been made:

1. Structural and rural transformation is impossible when farms are mainly small arid marginal.
2. A good price incentive can trigger investments in agriculture.
3. India needs to build value chains for high-value agri-products like livestock and horticulture.
4. Higher global prices of agricultural commodities are essential for India's poverty reduction.

Which of the above assumptions are valid?

(a) 1 and 3

(b) 2 and 4

(c) 2 and 3

(d) 3 and 4

Answer:(b)

27. Which one of the following statements best reflects the critical message of

the passage?

(b) India should create a large number of farmer producer companies

(c) Private investment in agriculture should be given priority over public investment.

(d) Inclusive agricultural growth is key to reduce poverty in the near future.

Answer:(d)

 Directions for the following 6 (six) items:

Read the following five passages and answer the items 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?

(a) Strong measures need to be taken to reduce the rural to urban migration of labour.

(b) The working condition in construction and unregistered manufacturing needs to be improved.

(c) service sector has been reducing the problem of unemployment.

(d) Increased social sector spending is imperative for large-scale job creation.

Answer: (d)

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.

1. On the basis of the above passage, the following assumptions have been made:

2. State should have some institutions to ensure its appropriate role in a digital society.

3. State should ensure that private parties do not violate the citizens' right to privacy.

4. Digital economy is not compatible with the idea of not violating the citizens’ privacy.

2. Which of the above assumptions is/are valid?

(a) 1 and 2

(b) 3 Only

(c) 1 and 3

(d) 2 only
