## घ लोक सेता शागो **Directions for the following 4 (four) items:** Read the following two passages and answer the items that follow the passages. Your answers to these items should be based on the passages only. ### Passage-1 According to the Food and Agriculture Organization, one-third of food produced for human consumption is lost or wasted globally. Food is lost or wasted throughout the supply chain, from initial agricultural production to final household consumption. The increasing wastage also results in land degradation by about 45%, mainly due to deforestation, unsustainable agricultural practices, and excessive groundwater extraction. The energy spent over wasted food results in about 5 billion tonnes of carbon dioxide production every year. Decay also leads to harmful emissions of other gases in the atmosphere. Addressing the loss and wastage of food in all forms is critical to complete the cycle of food efficiency and food sustainability. **1. Which of the following statements best reflect the most logical and rational inferences that can be made from the passage?** 1. The current methods of food distribution are solely responsible for the loss and wastage of food. 2. Land productivity is adversely affected by the prevailing trend of food loss and wastage. 3. Reduction in the loss and wastage of food results in lesser carbon footprint. 4. Post-harvest technologies to prevent or reduce the loss and wastage of food are not available. **Select the correct answer using the code given below.** (a) 1, 2 and 3 (b) 2 and 3 only (c) 1, 3 and 4 (d) 1, 2 and 4 **2. Based on the above passage, the following assumptions have been made:** 1. The food distribution mechanism needs to be reimagined and made effective to reduce the loss and wastage of food. 2. Ensuring the reduction of wastage and loss of food is a social and moral responsibility of all citizens. **Which of the assumptions given above is/are valid?** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 ### Passage-2 As inflation rises, even governments previously committed to budget discipline are spending freely to help households. Higher interest rates announced by central banks are supposed to help produce modest fiscal austerity, because to maintain stable debts while paying more to borrow, governments must cut spending or raise taxes. Without the fiscal backup, monetary policy eventually loses traction. Higher interest rates become inflationary, not disinflationary, because they simply lead governments to borrow more to pay rising debt-service costs. The risk of monetary unmooring is greater when public debt rises, because interest rates become more important to budget deficits. **3. Which of the following statements best reflects/reflect the most logical and rational inference/inferences that can be made from the passage?** 1. Central banks cannot bring down inflation without budgetary backing. 2. The effects of monetary policy depend on the fiscal policies pursued by the government. **Select the correct answer using the code given below.** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 **4. Based on the above passage, the following assumptions have been made:** 1. Fiscal policies of governments are solely responsible for higher prices. 2. Higher prices do not affect the long-term government bonds. **Which of the assumptions given above is/are valid?** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 **5. What is the least possible number of cuts required to cut a cube into 64 identical pieces?** (a) 8 (b) 9 (c) 12 (d) 16 **6.

Your answers to these items should be based on the passages only. ### Passage-1 Today, if we consider cities such as New York, London and Paris as some of the most iconic cities in the world, it is because plans carrying a heavy systems approach were imposed on their precincts. The backbone of the systems theory is the process of translating social, spatial and cultural desirables into mathematical models using computing, statistics, optimization and an algorithmic way of formulating and solving problems. The early universities of the West which began to train professionals in planning, spawned some of the most ingenious planners, who were experts in these domains. This was because these very subjects were absorbed into the planning curriculum that had its roots in the social sciences, geography and architecture. Planning in India, and its education differ from the West. **11. Which one of the following statements best reflects the most logical and rational inference that can be made from the above passage?** (a) Curriculum for urban planning courses should have diverse and interdisciplinary approach. (b) In India, city administration is under bureaucracy which lacks formal training in urban planning and management. (c) In India, the management of urban areas is a local affair with a chronic problem of insufficient funds. (d) With high density of population and widespread poverty in our urban areas, planned development in them is very difficult. **12. Based on the above passage, the following assumptions have been made:** 1. India needs a new generation of urban professionals with knowledge relevant to modern urban practice. 2. Indian universities at present have no capacity or potential to impart training in systems approach. **Which of the assumptions given above is/are correct?** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 ### Passage-2 Not every voice on the internet commands the same kind of audience. When anonymous private entities with high capital can pay for more space for their opinions, they are effectively buying a louder voice. If political discourse in the digital sphere is a matter of outshining one's opponent till the election is won, then the quality of politics suffers. The focus of social media is restricted to the promotion of content that generates more user engagement, regardless of how inflammatory the content may be. **13. Which one of the following statements best reflects the central idea of the above passage?** (a) Constructed as a marketplace of views, social media ensures instant access to information. (b) Social media are not ideal or moral institutions but the products built by companies to make profits. (c) Social media have been created to strengthen democracies. (d) In today's world, social media are inevitable for well-informed social life. **14. Based on the above passage, the following assumptions have been made:** 1. Internet is not inclusive enough. 2. Internet can adversely affect the quality of politics in a country. **Which of the assumptions given above is/are valid?** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 **15. 222333 + 333222 is divisible by which of the following numbers?** (a) 2 and 3 but not 37 (b) 3 and 37 but not 2 (c) 2 and 37 but not 3 (d) 2, 3 and 37 **16.

Your answers to these items should be based on the passages only. ### Passage-1 By the time children reach class 8, the bulk of them tend to be in the age range of 13 years to 15 years. But in our country, about a quarter of children in class 8 struggle with reading simple texts and more than half are still unable to do basic arithmetic operations like division. Every year about 25 million young boys and girls from elementary school move into the life that lies for them beyond compulsory schooling. They cannot enter the workforce at least in the organized sector till they are 18. For many families, these children are the first from their families ever to get this far in school. Parents and children expect that such 'graduates' from school will go on to high school and college. Hardly anyone wants to go back to agriculture. On the other hand, abilities in terms of academic competencies are far lower than they should be even based on curricular expectations of class 8. **21. Based on the above passage, the following assumptions have been made:** 1. For effective school education, parents have greater role than the governments. 2. School curriculum that conforms to today's requirements and is uniform for the entire country may address the issues brought out. **Which of the assumptions given above is/are valid?** (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 **22. Which one of the following statements best reflects the central idea conveyed by the passage?** (a) Total eradication of poverty in the country will resolve the issue of under-performance of our school-children. (b) Monetary incentives to parents and teachers is a strategy to improve the children's academic performance. (c) Public policy should ensure that competencies and achievements of young people are aligned with their expectations. (d) India is not going to take advantage of the demographic dividend unless some school pass-outs go back to agriculture. ### Passage-2 We take it for granted now that science has a social responsibility. The idea would not have occurred to Newton or Galileo. They thought of science as an account of the world as it is, and the only responsibility that they acknowledged was to tell the truth. The idea that science is a social enterprise is modern, and it begins at the industrial revolution. We are surprised that we cannot trace a social responsibility. **23. Which one of the following statements best reflects the thinking of the author about the science?** (a) Science must value the commitment of the scientists. (b) Science is a product of civilized society and must be used for the promotion of scientific awareness in people. (c) Industrial revolution was made possible by the advancements in science. (d) Science must pursue truth but be responsible for social welfare. **24. Consider the sequence A_BCD _ BBCDABC _ DABC _ D that follows a certain pattern.

The tyranny of the classroom is that every learner is subjected to the same set of lectures in the same way for the same duration. In the end, a few learners shine, some survive, and the rest are left behind. After the fixed duration, the classroom model moves on, with not a thought spared for those left behind. This is how we end up with 10 percent employability in our graduates after a decade and half of formal education. Repeating the ineffectual script in the realm of skill education will not produce different results. **41.

Parents consider, usually, that the various moral problems which arise in adolescence are peculiarly their province. The options they express, however, are so dogmatic that the young seldom confide in them, and usually go their own way in secret. **43. Based on the above passage, the following assumptions have been made:** 1. The adolescent does not feel comfortable with his parents because they tend to be dominating and assertive. 2.
