Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only. Economic liberalization in India was shaped largely by the economic problems of the government than by the economic priorities of the people or by the long-term development objectives. Thus, there were limitations in conception and design which have been subsequently validated by experience. Jobless growth, persistent poverty and rising inequality have mounted as problems since economic liberalization began. And all these years later, four quiet crises confront the economy; agriculture, infrastructure, industrialization and education as constraints on the country's future prospects. These problems must be resolved if economic growth has to be sustained and transformed into meaningful development. Which of the assumptions given below is/are valid? 1. India's economy needs to be greatly integrated with the global economy so as to create a large number of jobs and to sustain its growth momentum. 2. Economic liberalization would cause large economic growth which would reduce poverty and create sufficient employment in the long run.

Read the following five passages and answer the items that follow. Your answers to these items should be based on the passages only.Private investment in general is volatile. Foreign private investment is more volatile because the available investment avenues are significantly greater (i.e., the entire world). Therefore, the responsibility of providing employment cannot be left to Foreign Direct Investment (FDI). The current FDI inflows are volatile over time and, across sectors and regions, which is a necessary consequence of their search for the highest returns. The adverse consequences are unstable employment and an accentuation of income and regional inequalities. A probable positive consequence of foreign investment is the inflow of new technology and its subsequent diffusion. However, the technology diffusion is not at all certain because the existing state of physical and human capital in India may prove inadequate for the diffusion. With reference to the above passage, the following assumptions have been made :1. Relying on foreign investment in the long run is not an economically sound policy.2. Policies must be undertaken to reduce volatility in foreign private investment.3. Policies must be undertaken to strengthen domestic private investment.4. Public investment should be given priority over private investment.5. Substantial public investment in education and health should be undertaken.Which of the above assumptions is / are valid?

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. People will invest in education whenever they are granted the economic freedom to fully enjoy its benefits. Again, this is for the obvious reason that the return on education increases as the level of economic freedom rises. When people, thanks to lower tax rates, are allowed to retain most of the higher income that they gain from each incremental level of education, it makes eminent sense to invest in education. On the other hand, when the government decides to tax the higher income of educated individuals at even higher rates, it makes very little sense to invest in educating oneself further. The same incentives apply to parents who decide on whether to invest in their children's education. With reference to the above passage, the following assumptions have been made :1. Lower tax rates in a country invariably translate into greater investments in higher education.2. Investment in the education of children ensures their economic freedom.3. Economic freedom has a positive impact on building up human capital.Which of the above assumptions is/are valid?

Read the following passage and answer the questions that follow. Your answers to these items should be based on the passage only. India is 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 of their healthy peers.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. 2. Girls should be encouraged to delay marriage and first pregnancy.3. Mothers should be encouraged to breastfeed their children immediately after birth.4. The supply of safe drinking water and proper sanitation facilities to all should be ensured.5.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. 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 themost logical and rational inferencethat can be made from the above passage?

ARivers and other wetlands should be protected under Ramsar Convention.
BEngineering water systems should be modernized and further augmented.
CWetlands need to be reinforced as more than just open sources of water.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. Many people understand the connection between solid waste management and health in terms of the consequences of unattended heaps of thy 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. In the context of India, which one of the following statements best reflects the critical message of the passage?

AIn India, the drainage networks are not separate for sewerage and storm water.
BUrban local bodies do not have enough resources and legislative authority to deal with the problems of waste management.
CSolid waste management should be integrated with the maintenance of drainage and sewerage networks.
DBad management of solid waste and sewerage systems by our municipalities is the reason for drinking water shortages in our cities.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. Many opportunities to harness the highly skewed, seasonal, and spatial distribution of monsoon flows, which occur in a four-month period from June to September annually, have been lost. Since these few months account for most of the rainfall and consequent freshwater availability, the need for holding rainwater in reservoirs, for subsequently releasing it for use over the year, is a necessity nobody can afford to overlook. Climate change will continue to affect weather conditions and create water shortages and excesses. While millions suffer from droughts and floods, waters in the country's many rivers flow unutilized and are discharged into the sea every year. With reference to the above passage, which of the following could be the most rational and practical implications for India? 1. Inter-linking of rivers should be undertaken. 2. A network of dams and canals should be built across the country for the proper distribution of water. 3. Farmers should be provided easy loans for digging borewells. 4. Usage of water for agriculture should be regulated by law. 5. Distribution of river water among regions should be regulated by the Union Government.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. 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. 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?

Read the following five passages and answer the items that follow. Your answers to these items should be based on the passages only.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 the 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.Which one of the following is the most logical and rational inference that can be made from the above passage?

AIndian banking system is not able to help the country in its economic growth.
BEconomic reforms that started in 1991 have not helped in improving the economy to expected levels.
CIndia lacks the institutional mechanism to deal with the failure of banks.
DEncouraging the foreign investments in our industrial sector is a good alternative to this sector's dependence on banks for credit.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only.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 of 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: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.

Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only. In India, authorities always look to store the maximum amount of water in reservoirs during the monsoon season, which is then used for irrigation and generation of electricity during the summer months. It is an internationally accepted practice that the water level of a reservoir should be kept below a certain level before the onset of the monsoon season. This is so that when monsoon rains come, there is space to store the excess rainwater and also so that water can be released in a regulated manner. But the authorities store the maximum amount of water in reservoirs even before the close of the monsoon, only to ensure greater electricity generation and irrigation.With reference to the above passage, the following assumptions have been made :1. High risks involved in holding maximum water in reservoirs are due to our over-dependence on hydropower projects.2. Storage capacity of dams should not be full before or during monsoon season. 3. Role of dams in flood control is underestimated in India.Which of the above assumptions is/are valid?

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. In India, agriculture still engages about half of its workforce, and about 85 per cent of its farms are small and marginal. Compared to China and 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 favor of agriculture in the wake of rising global prices. This boosted private investments in agriculture by more than 50%. As a result, agri-GDP growth touched 4.1% during 2007-2012 as against 2.4% during 2002-2007. The net surplus of agri-trade touched $25 billion in 2013-2014; real farm wages rose by 7% per annum. All this led to an unprecedented fall in poverty.Which one of the following statements best reflects the critical message of the above passage?

AIndia should create large-scale off-farm rural employment to reduce poverty in the near future.
BIndia should create a large number of farmer producer companies.
CPrivate investment in agriculture should be given priority over public investment.
DInclusive agricultural growth is key to reduce poverty in the near future.

Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only. The pulse variety 'Pusa Arhar 16' has the potential to be grown in the paddy-growing regions 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 importantly, Arhar straw, unlike paddy straw, is green and 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. All 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. Which of the following are the most rational inferences that can be made from the passage?1. Farmers' income will be higher with pulse cultivation than with paddy cultivation. 2. Pulse cultivation causes less pollution as compared to paddy cultivation.3. Pulse straw can be used to improve soil quality.4. In the context of northern Indian agriculture, paddy straw has no usefulness. 5. Mechanized agriculture is the main cause for stubble burning. Select the correct answer using the code given below.

Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only. Spanish ships in the late 16th century first brought the potato tuber from South America to Europe whereby in the early 19th century, it had 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. Which one of the following statements best reflects the critical message of the passage?

AFor introducing any foreign plant into a country, the soil and climatic conditions of that country should be suitable.
BAs a staple food of a country, tuber crops like potato cannot replace cereal crops.
CSome of the fungal infections of plants cannot be prevented or stopped from spreading across large areas.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. 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 lose 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 statementsbest impliesthe suggestion given by the author of the passage?

ADistribute your wealth across different kinds of assets so that your risks would be minimized.
BRisk - taking behaviour should be a necessary component of your personality if you want to generate wealth.
CWhile making investments, find a trustworthy asset management organization which would manage your wealth for you.

Read the following passage and answer the item that follows. Your answer to this item should be based on the passages only. Although most of the Genetically Modified (GM) crops cultivated now are generally 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 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.

Read the following passage and answer the items that follow. Your answers to these items should be based on the passage only. Economic liberalization in India was shaped largely by the economic problems of the government than by the economic priorities of the people or by the long-term development objectives.

Jobless growth, persistent poverty and rising inequality have mounted as problems since economic liberalization began. And all these years later, four quiet crises confront the economy; agriculture, infrastructure, industrialization and education as constraints on the country's future prospects. These problems must be resolved if economic growth has to be sustained and transformed into meaningful development. Which of the following is/are the most rational and logical inference/ inferences that can be made from the passage? 1.
