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?
2.2 On the basis of your reading of the above passage fill in any two of the following blanks.
b. humans
c. a python
d. prey
b. hardens
c. softens
d. breaks down
iii. Californian squirrels are ______________ rattlesnake poison.
a. afraid of
b. helpless against
c. resistant to
d. indifferent to
a. Liquid substances released from glands (para 2)
c. Particular (para 7)

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.
On the basis of your understanding of the passage, complete the statements given below with the help of the options that follow:
(a) Ravi gets his brain to work at peak level by
(ii) playing games that need brain activity.
(iii) cycling on a stationary bike.
(iv) taking tablets to pump up his brain.
(b) When nerve cells work during exercise then
(ii) the brain is strengthened by multiplying them.
(iii) you start to lose your temper.
(iv) your stationary cycle starts to beep.
Answer the following questions briefly:
(c) How does exercise help the brain?
(d) Why does Ravi do a circuit of 'ride, work, ride'?
(e) What is the work of neurotransmitters?
(f) What benefits other than greater brain activity does one get from cycling?
(g) Why is exercise so important for adults?
(h) How is exercise itself a stress?
(ii) inactive (para 4)
Read the passage given below:
People tend to amass possessions, sometimes without being aware of doing so. They can have a delightful surprise when they find something useful which they did not know they owned. Those who never have to change house become indiscriminate collectors of what can only be described as clutter. They leave unwanted objects in drawers, cupboards, and attics for years in the belief that they may one day need them. Old people also accumulate belongings for two other reasons, lack of physical and mental energy, and sentiment. Things owned for a long time are full of associations with the past, perhaps with the relatives who are dead, and so they gradually acquire a sentimental value.
Some things are collected deliberately in an attempt to avoid wastage. Among these are string and brown paper, kept by thrifty people when a parcel has been opened. Collecting small items can be mania. A lady cuts out from newspaper sketches of model clothes that she would like to buy if she had money. As she is not rich, the chances are that she will never be able to afford such purchases. It is a harmless habit, but it litters up her desk.
Collecting as a serious hobby is quite different and has many advantages. It provides relaxation for leisure hours, as just looking at one’s treasure is always a joy. One doesn’t have to go out for amusement as the collection is housed at home. Whatever it consists of - stamps, records, first editions of books, china – there is always something to do in connection with it, from finding the right place for the latest addition to verifying facts in reference books. This hobby educates one not only in the chosen subject but also in general matters which have some bearing on it.
There are other benefits also. One gets to meet like-minded collectors to get advice, compare notes, exchange articles, to show off one’s latest find. So one’s circle of friends grows. Soon the hobby leads to traveling, perhaps a meeting in another town, possibly a trip abroad in search of a rare specimen, for collectors are not confined to one country. Over the years one may well become an authority on one’s hobby and will probably be asked to give informal talks to little gatherings and then, if successful, to larger audiences.
(a) On the basis of your understanding of the above passage make notes on it using headings and sub-headings. Use recognizable abbreviations (wherever necessary-minimum four) and a format you consider suitable. Also, supply an appropriate title to it.

Read the following extract and answer the question given below: (11)
Researchers· recently announced the earth could actually
withstand up to 200,000 times the current population. They arrived at this figure by calculating the amount of heat a human body emits. and only at l ·3 million billion would the earth be too hot to be habitable. And though it would feel like being in a can of sardines if that figure were ever reached, the earth is capable of comfortably sustaining a population several times the current 6·5 billion.
In fact, fertility is actually on the decline worldwideThough
population has grown, the rate of growth has fallen sharply. Twenty years ago, the UN projected that population would reach l l · 16 billion in 2050, today they say it will reach only 9·37 billion. Moreover, human population will stabilize at about 11 ·5 billion.While this figure is almost twice the current one, it is hardly claustrophobic.
True, the demands on resources are heavy even now, but this is more due to the manner in which these resources are being used. In fact, figures show that a bigger population does not amount to greater consumption. Over 20% of the world 's people in the highest income countries account for 86% of total private consumption expenditure - the poorest 20% a tiny 1 ·3%. With just 5% of the world's population, the US consumes about 40% of the world's resources. Would you say the US is overpopulated?
Concerns on scarcity of food are equally baseless. In fact, global food production has actually kept up with population growth . If people starve in many countries it is not because food is becoming scarce; it is because those people cannot afford it.
Questions:
(1) What conclusions did the researchers arrive at? (1)
( 2) How does the writer explain that the fertility is on the
decline? (2)
(3) What does the extract predict about the fear-, of scarcity of food? (2)
( 4) How will population become a gift in the global market
scene? (2)
(5) Rewrite the following sentences in the ways instructed:
(i) The earth could withstand upto 200,000 times the
current population.
(Rewrite the sentence using the modal auxiliary showing 'certainty'.) (I)
(ii) The earth would be too hot to be habitable.
(Remove ' too' and rewrite the sentence.) (1)
(iii) These resources are being used.
(Rewrite the sentence beginning with, 'We ............ ') (I)
( 6) Write the antonyms of:
(i) habitable (1/2)
.
(ii) stabilize ( 1/2 )
Read the following extract and answer the questions given
below :
In 1945 in Bay Roberts, Canada, a 12-year-old boy saw something in a shop window that set his heart racing. But the price -five dollars-was far beyond Reuben Earle's means. Five dollars would buy almost a week's groceries for his family.
Reuben couldn't ask his father for the money. Everything Mark Earle made by fishing, Reuben's mother, Dora, stretched like elastic to feed and clothe their five children.
Nevertheless, he opened the shop's weathered door and went inside. Standing proud and straight in his flour-sack shirt and washed out trousers, he told the shopkeeper what he wanted, adding, "but I don't have the money now. Can you please hold it for me?" ·
"I will try," the shopkeeper smiled. ''Folks around here don't usually have that kind of money to spend on things. It should keep for a while.,.
Reuben respectfully touched his worn cap and walked out into the May sunlight. The bay rippled in a freshening wind that ruffled his short hair. There was purpose in his loping stride. He
would raise the five dollars and not tell anybody.
Hearing the sound of hammering from a side street, Reuben had an idea.
He ran towards the sound and stopped at a construction site. People built their own homes in Bay Roberts, using nails purchased in burlap sack from a local factory. Sometimes the sacks were discarded in the flurry of buildings, and Reuben knew he could sell them back to the factory for five cents a piece.
(1) What did Reuben decide to do to raise the required amount?
(2) How much money did Reuben need? Why?
(3) Why couldn't Reuben ask his father for the money?
(4) What is special about the gifts which are given on special occasions?
(5) Rewrite the following sentences as directed :
(i) Reuben couldn't ask his father for the money.
(Rewrite the sentence using ' be able to'.)
(ii) Hearing the sound of hammering from a side street, Reuben had an idea.
(Rewrite the sentence using 'and'.)
(iii) He could sell them back to the factory.
·(Rewrite the sentence beginning with: 'They ..... ')
(6) Match the words in column 'A' with their meanings in
column 'B':
| column 'A' | column 'B' |
| folk | natural harbour |
| bay | sticks |

Read the passage given below:
During our growing up years we as children were taught both at home and school-to worship the photos and idols of the gods of our respective religions. When we grow a little older, we were to read holy books like The Bhagwad Gita, Bible, and Quran; we were told that there are a lot of life lessons to be learned from these holy books. We were then introduced to stories from our mythologies which taught us about ethics and morality-what is good and what is bad I also learned to be respectful towards my parents who made my life comfortable with their hard work and love and care, and my teachers who guided me to become a good student and a responsible citizen.
Much later in life, I realised that though we learn much from our respective holy books, there is a lot to learn from our surroundings. This realization dawned upon me when I learned to enquire and explore. Everything around us- the sun, the moon, the stars, rain, rivers, stones, rocks, birds, plants, and animals-teach us many valuable life lessons.
No wonder that besides the scriptures in many cultures nature is also worshipped. The message that we get is to save our environment and maintain ecological balance. People are taught to live in harmony with nature and recognize that there is God in all aspects of nature.
Nature is a great teacher. A river never stops flowing. If it finds an obstacle in its way in the form of heavy rock, the river water fights to remove it from its path or finds an alternative path to move ahead. This teaches us to be progressive in life, and keep the fighting spirit alive.
Snakes are worshipped as they eat insects in the field that can hurt our crops, thus protecting the grains for us. In fact, whatever we worship is our helper and makes our lives easy for us. There are many such examples in nature, but we are not ready to learn a lesson, Overcome with greed, we are destroying nature. As a result, we face natural disasters like drought, floods, and landslides. We don't know that nature is angry with us.
However, it is never too late to learn. If we learn to respect nature the quality of our life will improve.
2.1 Answer briefly the following questions:
(a) What are we taught in our childhood and growing up years?
(b) Why should we respect our parents and teachers?

The government of India is encouraging medical tourism in the country by offering tax benefits and export incentives to the participating hospitals. Medical visas are being cleared quickly without any hassles. With a view to facilitating the growth of medical tourism industry, the Ministry of Health and Family Welfare along with the Ministry of Tourism has set up a task force to evaluate the opportunities in the industry. Efforts are being made to standardise procedures and to guide foreign patients to select the hospitals most suited to their needs. Meanwhile, several private hospitals are seeking to take advantage of the booming medical tourism industry and are investing hugely in acquiring equipments and skills. However, medical tourism carries some risks that locally provided medical care does not. Some countries like India, Malaysia and Thailand have very different infectious diseases rarely found in Europe and North America. Exposure to disease without having built-up natural immunity can be a hazard for weak individuals specially with respect to gastrointestinal diseases like Hepatitis A, amoebic dysentery etc., which could slow down the recovery process. Also, medical tourists may be at risk from mosquito-transmitted diseases, influenza and tuberculosis. The quality of post-operative care can also vary dramatically depending on the hospital and the country. Finally, after returning home, a patient has limited contact with their surgeon. This may make it difficult to deal with any complications that may arise later, such as a delayed infection. The concept of medical tourism raises some important questions regarding accessibility, affordability and ethics in medical care. It is unfortunate that a large section of the Indian population has little or no access to private health care. Public health care system is inadequate and lacks proper infrastructure and facilities. One wonders if it is sensible to make provisions for medical tourism in a democratic country like India, which has failed to provide nourishment, sanitation and health care to its masses. |

Most cities, may not be prohibit hawking as a profession, but do place restrictions on the use of urban space. Therefore, a comprehensive study was conducted in 1998-99 on street vending, to provide concrete data for furthering the cause of the hawkers. Eight cities were selected - Mumbai, Ahmedabad, Kolkata, Imphal, Patna, Bhubaneswar and Bangalore.

Read the passage given below:
| (1) | When we think of the game of cricket, we come to the conclusion that it is primarily a game that depends on outstanding physical activities, good hand-eye coordination, speed, skill and strength. It provides entertainment and generates strong feelings of excitement. A good match of cricket or of any other game neither adds to the existing stock of human knowledge nor reveals any secret of existence. It does not carry any deep meaning but most people, particularly the lover of sports attach deep emotions and numerous meanings to it. Games are thought of as a metaphor for life. They are supposed to teach many lessons. In fact, more is said and written about a cricket match than about scientific findings or great philosophy. |
| (2) | This is because games, like a morality play, in which settings and rules are made by us, can easily make people test their fair and foul conduct, principles of reward and punishment, and emotions of joy and disappointment. They can make us experience the thrill of war without exposing us to its dangers. A man watching a cricket match on T.V. and munching popcorn is like a surrogate warrior. In fact, games provide us with a safe outlet for our aggressiveness. If games become aggressive, they lose the very purpose of providing entertainment and purging us of our aggressiveness. They can calm our impatience without creating any conflict. |
| (3) | Commentators, journalists, politicians and analysts can do a great favour to the competing teams by keeping the excitement within limits. The teams should play without being dominated by feelings of national honour and shame. Excellent performance of the players of both teams should be enjoyed and appreciated. Winning or losing in a game should not be taken seriously. A game is fun if it is played with true spirit of sportsmanship. |
Based on your understanding of the passage, answer the questions given below:
- Complete the sentence by choosing an appropriate option: (1)

- it depends only on skill and strength.
- Comment on the writer's reference to 'that cricket does not reveal any secret of existence. (1)
- List two responses to which watching a game of cricket gives rise to. (1)
- Select the option that conveys the opposite of 'destroy' from words used in the passage. (1)
- reveals
- experience
- generate
- purging
- The writer would not agree with the given statements based on paragraph 2, EXCEPT (1)
- Rules of any game are made by people.
- Watching a cricket match makes the viewer believe that he is fighting a battle.
- It is necessary for a game to be aggressive in order to build excitement.
