Read the given passage and answer the questions that follow.

Chanhudaro was a tiny settlement (less than 7 hectares) as compared to Mohenjodaro (125 hectares), almost exclusively devoted to craft production, including bead-making, shellcutting, metal-working, seal-making and weight-making. The variety of materials used to make beads is remarkable: stones like carnelian (of a beautiful red colour), jasper, crystal, quartz and steatite; metals like copper, bronze and gold; and shell, faience and terracotta or burnt clay. Some beads were made of two or more stones, cemented together, some of stone with gold caps. The shapes were numerous – disc shaped, cylindrical, spherical, barrel-shaped, segmented. Some were decorated by incising or painting, and some had designs etched onto them.

Techniques for making beads differed according to the material. Steatite, a very soft stone, was easily worked. Some beads were moulded out of a paste made with steatite powder. This permitted making a variety of shapes, unlike the geometrical forms made out of harder stones. How the steatite micro bead was made remains a puzzle for archaeologists studying ancient technology. Archaeologists’ experiments have revealed that the red colour of carnelian was obtained by firing the yellowish raw material and beads at various stages of production. Nodules were chipped into rough shapes, and then finely flaked into the final form. Grinding, polishing and finally drilling completed the process. Specialised drills have been found at Chanhudaro, Lothal and more recently at Dholavira. Nageshwar and Balakot, both settlements are near the coast. These were specialised centres for making shell objects – including bangles, ladles and inlay – which were taken to other settlements. Similarly, it is likely that finished products (such as beads) from Chanhudaro and Lothal were taken to the large urban centres such as Mohenjodaro and Harappa.

Which of these stones is very soft and easy to mould?

Read the following passage and answer the questions given after it.

The stark observation made in the Economic Survey of 2015-16 that “Indian agriculture, is in a way, a victim of its own past success – especially the green revolution”, shows the dark reality of the agriculture sector at present and the havoc that has been wreaked by the green revolution.

The green revolution, which is often characterised by the introduction of high-yielding variety of seeds and fertilisers, undoubtedly increased the productivity of land considerably. But the growth in the productivity has been stagnant in recent years, resulting in a significant decline in the income of farmers. There have also been negative environmental effects in the form of depleting water table, emission of greenhouse gases, and the contamination of surface and ground water. Needless to say, the agriculture sector is in a state of distress, which is severely affecting peasants and marginal farmers, and urgent policy interventions are required to protect their interests.

The government has responded to the problem by constituting a panel, which will recommend ways to double the income of farmers by 2022. While this may be an overtly ambitious target, if we want to boost stagnated agricultural growth a shift has to be made from food security of the nation to income security of the farmers. However, there are many hurdles that have to be crossed if we want to achieve this objective.

The first major barrier to overcome is declining productivity. Data from 2013 reveals that India’s average yield of cereal per hectare is far less than that of many countries (including several low income countries), but the difference is huge when compared to China. For instance, our average yield per hectare is 39% below than that of China and for rice this figure is 46%. Even Bangladesh, Vietnam and Indonesia fare better than India in case of rice yield. Further, there is a huge inter-regional variation; the wheat and rice yield from Haryana and Punjab is much higher than from the other states.

In order to cross the declining productivity barrier there is a need to herald a rainbow revolution by making a shift from wheat-rice cycle to other cereals and pulses. Since wheat and rice coupled with other crops are backed by minimum support prices (MSP) and input subsidy (whether water, fertiliser or power) regime, there is a huge incentive for the farmers in the irrigated region of Northwest India to grow these crops.

As per the passage, which country has the highest yield of rice per hectare?

Read the following passage carefully and answer the questions given below it. Certain words have been highlighted for your attention.

Most people spend (on average) half of their day tapping away at their hand-held devices. Either, surfing the net or checking notifications. Facebook ranks the highest in all social networking platforms, followed by Twitter, Instagram and so forth.

Social media is addictive- which is why so many people are 'hooked'. Often referred to as Social networking addiction, this phrase is often used to describe someone who spends too much time on Facebook, Twitter, Instagram and other channels. A blog post, Instagram post, tweet, or youtube video can be produced easily by anyone and shared, which can then be viewed by millions for free. Psychologists and scientists have now taken the time to study social media in terms of why they believe it interferes with aspects of our daily life. There is no official medical term that identifies addiction and social networking. It cannot be deemed as a disease or disorder as the cases are not severe and the habit can easily be maintained or prevented. Furthermore, instead of spending long periods of time on social media, we dip into and out of these sites all day long. We check for updates from friends and family as well as news and information. However, the behavior associated with the excessive use of these channels has become the subject of much public and sociological debate. We actively post, like, comment and share personal posts. Not only that, we tend to share and reshare expressions (of either negative or positive) contagiously. But, why?

Scientists believed some years ago that, dopamine was simply a pleasure chemical in the brain. Recent studies have shown that; dopamine actually produces the desire in people to 'want' by drawing out the need for us to -seek and search. Creating the ultimate drive to find what is that what we want.

Dopamine is spontaneous. It’s stimulated by unpredictability and small bits of information as well as reward cues which are the same conditions that social media presents to all users. In addition, the pull of dopamine is so strong that recent studies have shown that tweeting, for example, can be harder to resist than cigarettes and alcohol!

Researchers at Chicago University studied the effects of social media. They concluded quite quickly that people presented higher levels of addiction to social media than the need to smoke or drink. Media cravings ranked higher.

And, let’s not forget oxytocin, many call it the cuddle chemical because the brain releases pleasure chemicals that transpire usually when you kiss and hug- or tweet. It is also known as the hormone that builds the strong yet unique bond between mothers and their babies. Oxytocin is now regarded as the human stimulant of empathy, generosity, trust, and more. These are factors which many advertisers and marketers play on when promoting a brand or business over social media.

Nevertheless, problems have arisen most commonly with school kids - whereby mobile phone devices have been confiscated because exam results have fallen severely due to lack of attention on homework or studies. Schools in many westernized countries have had to take drastic action - banning smartphones, iPad and most portable devices from school premises- as it is claimed to be a huge distraction. Whereas, other schools use it for educational purposes and as a rewards system for their pupils.

Research has also indicated unsurprisingly that Facebook is the most common activity that university students switch to, when studying. Worryingly, it has also found that those who most engage in this type of internet browsing tend to have lower levels of educational achievement.

Also, there have been many cases of students posting or sharing content that is unethical, which has caused parents and academic institutions to limit the use of these online networking channels.

Why is Oxytocin regarded as the cuddle chemical?

Long ago men spent most of their time looking for food. They ate anything they could find. Some lived mostly on plants. They ate the fruit, stems, and leaves of some plants and the roots of others. When food was scarce, they ate the bark of trees. If they were lucky, they would find a bird’s nest with eggs. People who lived near the water ate fish or anything that washed ashore, even rotten whales. Some people also ate insects and small animals like lizards that were easy to kill.

Later, men learned to make weapons. With weapons, they could kill larger animals for meat. These early people had big appetites. If they killed an animal, they would drink the blood, eat the meat, and chew the bones. When they finished the meal, there was nothing left.

At first men wandered from place to place to find their food. But when they began to grow plants, they stayed in one place and ate what they could grow. They tamed animals, trained them to work, and killed them for meat. Life was a little better then, but there was still not much variety in their meals. Day after day people ate the same food.

Gradually men began to travel greater distances. The explorers who sailed unknown seas found new lands. And in these lands they found new food and spices and took them back home.

The Portuguese who sailed around the stormy Cape of Good Hope to reach China took back “Chinese apples”, the fruit we call oranges today. Later, Portuguese colonists carried orange seeds to Brazil. From Brazil oranges were brought to California, the first place to grow oranges in the United States. Peaches and melons also came from China. So did a new drink, tea.

Where did oranges come from?

There is a general consensus that ‘International Understanding’ need to be taught as a separate subject at the school stage as that would add to the curricular load which is already too heavy. Instead it should be woven into the curriculum and the numerous opportunities that present themselves while teaching normal school subjects may be intelligently and imaginatively used by the teacher to promote International Understanding.

The school subjects which can be most profitably used for this purpose are History, Geography, Civics, Economics, Sociology, Political Science, Social Sciences, Languages as well as Physical and Life Sciences. However, at the higher education level, international education can be prescribed as a separate subject of study. In fact, the present situation in India broadly conforms to this consensus so far as the school stage is concerned.

At the under-graduate and the post-graduate levels, courses of study in subjects like History, Geography, Economics, Political Science, International Relations, International Law and International Organization have been prescribed by most of the universities and these contain content which has a direct or indirect bearing on promoting UNESCO ideals
