Q.1783Miscellaneous2024Easy

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 3:5 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 sufficiency and food sustainability. 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?

Q.1787Miscellaneous2024Easy

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. 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.

Q.1793Miscellaneous2024Easy

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 models mathematical 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. 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?

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 sense further back, because we nurse the illusion that the industrial revolution ended a golden age. Which one of the following statements best reflects the thinking of the author about the science?

Q.1799Miscellaneous2024Easy

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 all 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. Which one of the following statements best reflects the central idea conveyed by the passage?

Q.1800Miscellaneous2024Easy

Only with long experience and opening of his wares on many a beach where his language is not spoken, will the merchant come to know the worth of what he carries, and what is parochial and what is universal in his choice. Such delicate goods as justice, love and honour, courtesy, and indeed all the things we care for, are valid everywhere but they are variously moulded and often differently handled, and sometimes nearly unrecognizable if you meet them in a foreign land, and the art of learning fundamental common values is perhaps the greatest gain of travel to those who wish to live at ease among their fellows. With reference to the above passage, the following assumptions have been made : 1. Travel leads to an understanding of humans. 2. Travel helps those who wish to learn fundamental common values. 3. A person with long experience in travel can resolve differences amongst people. Which of the assumptions given above are valid?
