One of the greatest advances in modern technology has been the invention of computers. They are widely used in industries and in universities. Now there is hardly any sphere of human life where computers have not been pressed into service of man. We are heading fast towards the day when a computer will be as much part of man's daily life as a telephone or a calculator.
Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic jams. This whole process by which machines can be used to work for us has been called 'automation'. In the future 'automation' may enable human beings to enjoy more leisure than they do today. The coming of automation is bound to have important social consequences.
Some years ago an expert on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could 'think'. There is no possibility that human beings will be "controlled by machines". Though computers are capable of learning from their mistakes and improving on their performance, they need detailed instructions from human beings to operate. They can never, as it were, lead independent lives or "rule the world" by making decisions of their own.
Sir Leon said that in future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions. Car drivers can be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications.
a) What is the greatest advancement in modern technology?
b) What complicated works are computers capable of doing?
c) Write one use of computers.
d) Explain automation.
e) Why can't computers lead independent lives or rule the world?
f) How would computers as translating machines help people?
g) What was the prediction of Sir Leon about computers in the future?

Read the passage given below:
1. Every morning Ravi gives his brain an extra boost. We're not talking about drinking strong cups of coffee or playing one of those mind-training video games advertised all over Facebook. "I jump onto my stationary bike and cycle for 45 minutes to work," says Ravi. "When I get to my desk, my brain is at peak activity for a few hours." After his mental focus comes to a halt later in the day, he starts it with another short spell of cycling to be able to run errands.
2. Ride, work, ride, repeat. It's scientifically proven system that describes some unexpected benefits of cycling. In a recent study in the Journal of Clinical and Diagnostic Research, scientists found that people scored higher on tests of memory, reasoning, and planning after 30 minutes of spinning on a stationary bike than they did before they rode the bike. They also completed the tests faster after pedalling.
3. Exercise is like fertilizer for your brain. All those hours spent on exercising your muscles, create rich capillary beds not only in leg and hip muscles, but also in your brain. More blood vessels in your brain and muscles mean more oxygen and nutrients to help them work. When you pedal, you also force more nerve cells to fire. The result: you double or triple the production of these cells – literally building your brain. You also release neurotransmitters (the messengers between your brain cells) so all those cells, new and old, can communicate with each other for better, faster functioning. 'That's a pretty profound benefit to cyclists.
4. This kind of growth is especially important with each passing birthday, because as we age, our brains shrink and those connections weaken. Exercise restores and protects the brain cells. Neuroscientists say, "Adults who exercise display sharper memory skills, higher concentration levels, more fluid thinking, and greater problem-solving ability than those who are sedentary."
5. Cycling also elevates your mood, relieves anxiety, increases stress resistance, and even banishes the blues. "Exercise works in the same way as psychotherapy and antidepressants in the treatment of depression, maybe better," says Dr. Manjari. A recent study analyzing 26 years of research finds that even some exercise – as little as 20 to 30 minutes a day – can prevent depression over the long term.
6. Remember: although it's healthy, exercise itself is a stress, especially when you're just getting started or getting back into riding. When you first begin to exert yourself, your body releases a particular hormone to raise your heart rate, blood pressure, and blood glucose levels, says Meher Ahluwalia, PhD, a professor of integrative physiology. As you get fitter, it takes a longer, harder ride to trigger that same response.

Read the following extract and complete the table given below:
Children are perpetually asking questions. As adults, we are awkward with questions. We link the act of asking questions to ignorance. It indicates that we do not know; hence, we may look stupid while asking questions.
Children have no shame, whereas adults suffer from layers and layers of shame. Because children have no shame, they are more capable of failing at something and moving on from it. Our sense of shame makes us inhibited. So we do not try new things at work.
Children quickly make friends with strangers. Put two small kids alongside a few toys and they will start playing before they care to know about each other’s antecedents. As adults, we seek the false comfort of known relationships before we agree to play with each other.
Children freely express their emotions; adults learn to suppress their emotional side. We come to the workplace and are frequently counselled, “Do not get emotional.”
Children play. They find play in everything. Adults shun play and consider it the opposite of “serious work”. To a child, every act is an act of play.

Read the passage given below carefully and answer the questions that follow.
1. Overpowering prey is a challenge for creatures that do not have limbs. Some species like Russell's viper inject poison. Some others opt for an alternative non-chemical method – rat snakes, for instance, catch and push their prey against the ground, while pythons use their muscle power to crush their prey to death. But snakes can't be neatly divided into poisonous and non-poisonous categories.
2. Even species listed as non-poisonous aren't completely free of poison. The common Sand Boa, for instance, produces secretions particularly poisonous to birds. So the species doesn't take any chance – it crushes its prey) and injects poison as an extra step.
3. Do vipers need poison powerful enough to kill hundreds of rats with just one drop? After all, they eat only one or two at a time.
4. While hunting animals try their worst to kill most efficiently, their prey uses any trick to avoid becoming a meal, such as developing immunity to poison.) For instance, Californian ground squirrels are resistant to Northern Pacific rattlesnake poison.
5. Competition with prey is not the only thing driving snakes to evolve more and more deadly poison. Snakes also struggle to avoid becoming prey themselves.
6. Some snake killers have partial immunity to poison. Famously, mongooses are highly resistant to cobra poison, and with their speed and agility, kill snakes fearlessly. It would be the death of cobras as a species if they didn't evolve a more deadly poison to stop mongooses.
7. Poison has another important role. It's an extreme meat softener, specific enzymes break up the insides of the prey. Normally, a reptile depends on the sun's warm rays to aid digestion.
8. But I wonder if we cannot use venom in our favour. In remote parts of India, local hospitality often involves leather tough meat. I chew and chew until my jaws ache. If I spit it out or refuse, our hosts would be offended, I swallow like a python stuffing a deer down its throat and hope I don't choke. If only I had poison.
(b) How does Sand Boa kill its prey?
(c) There is a constant tussle between the hunting animal and its prey? Why?
(e) What difficulty does the writer face when he is entertained in the remote parts of India?

Read the passage given below.
Then all the windows of the grey wooden house (Miss Hilton used to live here. She expired last week.), were thrown open, a thing I had never seen before.
At the end of the day a sign was nailed on the mango tree: FOR SALE.
Nobody in the street knew Miss Hilton. While she lived, her front gate was always locked and no one ever saw her leave or saw anybody go in. So even if you wanted to, you couldn't feel sorry and say that you missed Miss Hilton.
When I think of her house I see just two colours. Grey and green. The green of the mango tree, the grey of the house, and the grey of the high iron fence that prevented you from getting at the mangoes.
If your cricket ball fell in Miss Hilton's courtyard you never got it back. It wasn't the mango season when Miss Hilton died. But we got back about ten or twelve of our cricket balls.
The house was sold and we were prepared to dislike the new owners ever before they came. I think we were a little worried. Already we had one resident of the street who kept on complaining about us to our parents. He complained that we played cricket on the pavment; and if we were not playing cricket he complained that we were making too much noise anyway.
One afternoon, when I came back from school Pal, said, "Is a man and a woman. She pretty pretty, but he ugly like hell". I didn't see much. The front gate was open, but the windows were shut again. I heard a dog barking in an angry way.
One thing was settled pretty quickly. Whoever these people were they would never be the sort of people to complain that we were making noise and disturbing their sleep.
A lot of noise came from the house that night. The radio was going at full volume until midnight when the radio station closed down. The dog was barking and the man was shouting. I didn't hear the woman.
On the basis of your understanding the above passage complete the following statements :
(a) Nobody went into Miss Hilton's house because her front __________.
(b) Her house had only two colours, (i) __________ and (ii) __________.
(c) High iron fence did not let the boys get __________.
(d) They never got it back if their __________ fell into her courtyard.

Read the passage given below and answer the questions that follow:
| 1. | A fisherman, enfeebled with age, could no longer go out to sea so he began fishing in the river. Every morning he would go down to the river and sit there fishing the whole day long. In the evening he would sell whatever he had caught, buy food for himself and go home. It was a hard life for an old man. One hot afternoon while he was trying to keep awake and bemoaning his fate, a large bird with silvery feathers alighted on a rock near him. It was Kaha, the heavenly bird. “Have you no one to care for you, grandpa?” asked the bird. “Not a soul.” “You should not be doing such work at your age,” said the bird. “From now on I will bring you a big fish every evening. You can sell it and live in comfort.” True to her word, the bird began to drop a large fish at his doorstep every evening. All that the fisherman had to do was take it to the market and sell it. As big fish were in great demand, he was soon rolling in money. He bought a cottage near the sea, with a garden around it and engaged a servant to cook for him. His wife had died some years earlier. He had decided to marry again and began to look for a suitable woman. |
| 2. | One day he heard the royal courtier make an announcement. Our king has news of a great bird called Kaha,” said the courtier. “Whoever can give information about this bird and help catch it, will be rewarded with half the gold in the royal treasury and half the kingdom!” The fisherman was sorely tempted by the reward. Half the kingdom would make him a prince! |
| 3. | “Why does the king want the bird,” he asked. “He has lost his sight,” explained the courtier. “A wise man has advised him to bathe his eyes with the blood of Kaha. Do you know where she can be found?” “No…I mean …no, no…” Torn between greed and his sense of gratitude to the bird, the fisherman could not give a coherent reply. The courtier, sensing that he knew something about the bird, informed the king. The king had him brought to the palace. |
| 4. | “If you have information about the bird, tell me”, urged the king. “I will reward you handsomely and if you help catch her, I will personally crown you king of half my domain.” “I will get the bird for you,” cried the fisherman, suddenly making up his mind. “But Kaha is strong. I will need help. The king sent a dozen soldiers with him. That evening when the bird came with the fish, the fisherman called out to her to wait. “You drop the fish and go and I never get a chance to thank you for all that you‘ve done for me," he said. “Today I have laid out a feast for you inside. Please alight and come in. Kaha was reluctant to accept the invitation but the fisherman pleaded so earnestly that she finally gave in, and alighted. The moment she was on the ground, the fisherman grabbed one of her legs and shouted to the soldiers hiding in his house to come out. They rushed to his aid but their combined effort could not keep Kaha down. |
| 5. | She rose into the air with the fisherman still clinging to her leg. By the time he realised he was being carried away, the fisherman was too high in the air to let go. He hung on grimly, and neither he nor Kaha was ever seen again. |
Based on your understanding of the above passage, answer the questions.
- Why did the fisherman start fishing in the river?
- How did the fisherman spend the day before he met Kaha?
- How did the fisherman betray Kaha?
- Why was the fisherman doubtful about revealing information about Kaha to the courtier?
Read the passage given below.
| 5 | Changing food preferences have brought about rapid changes in the structure of the Indian diet. The rapid proliferation of multinational fast food companies and the influence of Western culture have replaced traditional home-cooked meals with ready-to-eat, processed foods thus increasing the risk of chronic diseases in urban Indians. Therefore, nurturing healthy eating habits among Indians from an early age would help to reduce health risks. |
| 10 | To date, little is known about the quality and quantity of foods and beverages consumed by urban Indian adolescents. This lack of evidence is a significant barrier to the development of effective nutrition promotion and disease prevention measures. |

Therefore, a self-administered, semi-quantitative, 59-item meal-based food frequency questionnaire (FFQ) was developed to assess the dietary intake of adolescents. A total of 1026 students (aged 14-16 years) attending private, English-speaking schools in Kolkata completed the survey. A sample percentage of the food consumption pattern is displayed.
The survey results report poor food consumption patterns and highlight the need to design healthy eating initiatives. Interestingly, while there were no gender differences in the consumption of legumes and fried snacks, the survey found more females consumed cereals, vegetables and fruits than their male counterparts. |
| 25 | In conclusion, the report suggested that schools ought to incorporate food literacy concepts into their curriculum as they have the potential of increasing the fruit and vegetable intake of teenagers. Additionally, healthy school canteen policies with improved availability, accessibility, variety and affordability of healthy food choices would support the consumption of nutritious food in students. |
Based on your understanding of the passage, answer the questions given below.
- What does the researcher mean by ‘changing food preferences'?
- Why was this survey on the food consumption of adolescents undertaken?
- With reference to the above figure, write one conclusion about students' consumption of energy-dense drinks.
- What can be concluded from the ‘no intake’ data of fruit consumption versus energy-dense snacks, with reference to the above figure?
- There were gender differences observed in the consumption of healthy foods, according to the survey. Substantiate.
- Why is ‘affordability’ recommended as a significant feature of a school canteen policy?
- Identify a word from lines 9-18 indicating that the questionnaire was specifically designed to be completed by a respondent without the intervention of the researcher collecting the data.
Read the following text.
| (1) | Reduction in green areas has caused various environmental problems. People squeezed between concrete structures are looking for various ways to meet their longing for green. One of the ways to do so, is vertical gardens and green walls. Vertical gardening is a unique method of gardening where plants are grown in a vertical position or upward, rather than in the traditional method of planting them on the ground. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| (2) | The purpose of vertical gardens and green walls, which arises from the studies of different disciplines (landscape architects, architects, engineers, etc.), is to close the cold image of concrete and increase the visual value. In these systems, nature and structures are integrated, and thus, urban areas and the desired environment have become intertwined. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| (3) | Vertical garden case studies often show that, though functionality should be in the foreground when vertical gardens are planned, they are generally made as aesthetic elements in the city's underpasses and city squares and decorative elements in residences without seeking functionality. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| (4) | Experts support that the visual quality and evaluation of landscape architecture are determined based on the satisfaction of the users. Hence, a survey questionnaire was prepared for residents of varied age groups from of a metropolitan city. The given Table 1, displays these responses: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| (5) | The study acknowledged that vertical gardening has the potential to transform urban spaces into green, sustainable areas, and further research should explore the impact of vertical gardening on the environment and human well-being. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Answer the following questions, based on the passage above.
i. Complete the following analogy appropriately, based on your understanding of paragraphs 1 & 2. (1)
We can say that the situation of people living in concrete structures is comparable with a fish living in a fishbowl, and the need for vertical gardens to the need for decorations in the fishbowl because ______.
ii. Fill the blanks with the appropriate option from those given in brackets, based on your understanding of paragraph 2. (1)
The statement that urban spaces have become more closely connected with the desired natural surroundings through the incorporation of nature and structures in vertical gardens and green walls is a _______ (fact/ opinion) because it is a _______ (subjective judgement/ objective detail).
iii. Justify the following, in about 40 words. (2)
While the survey results suggest that vertical gardens may be effective in improving the quality of life in urban areas, further research and evaluation may be necessary to fully understand their effectiveness and potential drawbacks.
iv. Based on the survey results, which two concerns should a city government, looking to install vertical gardens, address? (1)
v. In Table 1, statement 3, "Vertical gardens increase air quality - indoors and outdoors," received the most neutral responses from participants, with 51 respondents indicating a neutral stance. State any one inference that can be drawn from this. (1)
vi. Select the option that correctly displays what ‘intertwined’ signifies. (Reference-Paragraph 2) (1)
