प्रश्न
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)
उत्तर
2.1
(a) While Russell’s viper injects poison, the rat snakes catch and push their prey against the ground.
(b) The Sand Boa produces secretions particularly poisonous to birds. It does not take any chances and first crushes its prey and then injects poison as an extra step.
(c) 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. 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.
(d) Mongooses are highly resistant to cobra poison, and with their speed and agility, kill snakes fearlessly.
(e) When the writer is entertained in the remote parts of India, local hospitality often involves leather-tough meat. The writer chews it until his jaw aches. If he spits it out or refuses, their hosts would be offended and if he swallows, it would be like python stuffing a deer down its throat and hope that it doesn’t choke. Thus, he regrets not having a venom which he could use to soften the meat.
2.2
(i) Californian squirrels are prey rattlesnake poison.
(ii) Poison softens meat.
(iii) Californian squirrels are resistant to rattlesnake poison.
2.3

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 passage given below and answer the questions that follow:
The most alarming of man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with lethal materials. This pollution is for the most part irrevocable; the chain of evil it initiates is for the most part irreversible. In this contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world; radiation released through nuclear explosions into the air, comes to the earth in rain, lodges into the soil, enters the grass or corn, or wheat grown there and reaches the bones of a human being, there to remain until his death. Similarly, chemicals sprayed on crops lie long in soil, entering living organisms, passing from one to another in a chain of poisoning and death. Or they pass by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and harm those who drink from once pure wells.
It took hundreds of millions of years to produce the life that now inhabits the earth and reached a stage of adjustment and balance with its surroundings. The environment contained elements that were hostile as well as supporting. Even within the light of the sun, there were short wave radiations with power to injure. Given time, life has adjusted and a balance reached. For time is the essential ingredient, but in the modern world is no time.
The rapidity of change and the speed with which new situations are created follow the heedless pace of man rather than the deliberate pace of nature. Radiation is no longer the bombardment of cosmic rays; it is now the unnatural creation of man’s tampering with the atom. The chemicals to which life is asked to make adjustments are no longer merely calcium and silica and copper and all the rest of the minerals washed out of the rocks and carried in the rivers to the sea; they are the synthetic creations of man’s inventive mind, brewed in his laboratories, and having no counterparts in nature.
(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 a title to it.
(b) Write a summary of the passage in about 80 words.

“Pluck the flowers off”, said the other boy and the daisy trembled for fear, for to be pulled off meant death
to it; and it wished so much to live, as it was to go with the square of turf into the poor captive lark’s cage.
“No, let it stay,” said the other boy, “it looks so pretty.” And so it stayed, and was brought into the lark’s cage. The poor bird was lamenting its lost liberty, and beating its wings against the wires; and the little daisy could not speak or utter a consoling word, much as it would liked to do so. So the forenoon passed. “I have no water,” said the captive lark, “they have all gone out and forgotten to give me anything to drink. My throat is dry and burning. I feel as if I had fire and ice within me and the air is so oppressive. Alas! I must die, and part with the warm sunshine, the fresh green meadows, and all the beauty that God has created.” And it thrust its beak into the piece of grass, to refresh itself a little. Then it noticed the little daisy, and nodded to it, and kissed it with its beak and said : “You must also fade in here, poor little flower. You and the piece of grass are all they have given me in exchange for the whole world, which I enjoyed outside. Each little blade of grass shall be a green tree for me, each of your white petals a fragrant flower. Alas! You only

Read the following extract and answer the questions given below:
But being named an 'AdarshGaon' is far from easy. Villages had to give a proposal after which a committee headed by Mr. Pawar inspected the villages. "The Villages had to show dedication in the struggle to fight mediocrity. They had to follow all the conditions of becoming an 'AdarshGaon'. We chose villages with a revolutionary spark, "Mr. Pawar says.
Villages need to follow strict rules. The process begins with effective water management through the watershed technique and water auditing. taking responsibility for the village's natural resources-planting trees and stopping grazing. contributing labour for the village work, and then expanding to bring about behavioral changes in the people for harboring social change. Hiware Bazaar is free of any kind of addiction and there are no liquor or tobacco shops in the village. Vasectomy has been made compulsory, as is the pre-marital HIV test.
The 'AdarshGaon' model prides itself on being based on the joint decisions made by the Gram Sabha, where all the villagers are present. Even while selecting the new villages under the scheme, Mr. Pawar made sure that the decision to become an ideal village was taken by the entire village together.
The greatest victory for Hiware Bazaar so far has been the reverse migration that the village has witnessed since 1989. As many as 93 families have come back to the village," from the slums in Mumbai and Pune," Mr. Pawar says.

Read the passage given below :
Success
Everybody wants to succeed in life. For some, success means achieving whatever they desire or dream. For many, it is the name, fame, and social position. Whatever be the meaning of success, it is a success that makes a man popular.
All great men have been successful. They are remembered for their great achievements. But it is certain that success comes to those who are sincere, hardworking, loyal, and committed to their goals.
Success has been man's greatest motivation. It is very important for all. Success has a great effect on life. It brings pleasure and pride. It gives a sense of fulfillment. It means all-around development. Everybody hopes to be successful in life. But success smiles on those who have a proper approach, planning, vision, and stamina. A proper and timely application of all these things is bound to bear fruit. One cannot be successful without cultivating these certain basic things in life. It is very difficult to set out on a journey without knowing one's goals and purposes. The clarity of the objective is a must to succeed in life. A focused approach with proper planning is certain to bring success. Indecision and insincerity are big obstacles on the path to success.
One should have the capability, capacity, and resources to turn one's dreams into reality. Mere desire cannot bring you success. The desire should be weighed against factors like capability and resources. This is the basic requirement of success. The next important thing is the eagerness, seriousness, and the urge to be successful. It is the driving force that decides success. It is the first step on the ladder of success.
One needs to pursue one's goals with all one's sincerity and passion. One should always be in high spirits. Lack of such spirit leads to an inferiority complex which is a big obstruction on the path to success. Time is also a deciding factor. Only the punctual and committed have succeeded in life. The lives of great men are examples of this. They had all these qualities in plenty which helped them rise to the peak of success.
Hard labor is one of the basic requirements of success. There is no substitute for hard labor. It alone can take one to the peak of success. Every success has a ratio of five percent inspiration and ninety-five percent perspiration. It is patience, persistence, and perseverance which play a decisive role in achieving success. Failures are the pillars of success as they are our stepping-stones and we must get up and start again and be motivated.
2.1 On the basis of your reading of the passage, answer any four of the following questions in 30-40 words each:
(a) To whom does success come certainly?
(b) What are the basic things in life we need to achieve success?
(c) What did great men have in plenty to rise to the peak of success? Give any two examples
(d) What is the one basic requirement of success?
(e) Explain: "Failures are pillars of success."
2.2 On the basis of your reading of the passage, fill in any two of the following blanks with appropriate words/phrase :
(a) ________________ plays a decisive role in achieving success.
(b) Goals have to be pursued with ________________ and ________________
(c) Ratio of success is ________________ inspiration.
2.3 Find out the words from the passage that mean the same as the following :
(a) endurance (para 2)
(b) obstruction (para 4)
(c) motivation (para 5)
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 passage given below:
| (1) | Seagulls, as you know, never falter, never stall. To stall in the air is for them a disgrace and a dishonour. But Jonathan Livingston Seagull, unashamed, stretching his wings again in that trembling hard curve – slowing, slowing, and stalling once more –was no ordinary bird. Most gulls don't bother to learn more than the simplest facts of flight – how to get from shore to food and back again. For most gulls, it is not flying that matters, but eating. For this gull, though, it was not eating that mattered, but flight. More than anything else, Jonathan Livingston Seagull loved to fly. |
| (2) | This kind of thinking, he found, is not the way to make oneself popular with other birds. Even his parents were dismayed as Jonathan spent the whole day alone, making hundreds of low-level gliders, experimenting. "Why, Jon, why?" his mother asked. "Why is it so hard to be like the rest of the flock, Jon? Why can't you leave low flying to the pelicans, the albatross? Why don't you eat? Son, you're bone and feathers!" "I don't mind being bone and feathers, Mom. I just want to know what I can do in the air and what I can't, that's all. I just want to know." "See here Jonathan," said his father, not unkindly. "Winter isn't far away. Boats will be few, and the surface fish will be swimming deep. If you must study, then study food, and how to get it. This flying business is all very well, but you can't eat a glide, you know. Don't you forget that the reason you fly is to eat?" |
| (3) | Jonathan nodded obediently. For the next few days, he tried to behave like the other gulls; he really tried, screeching and fighting with the flock around the piers and fishing boats, diving on scraps of fish and bread. But he couldn't make it work. It wasn't long before Jonathan Gull was off by himself again, far out at sea, hungry, happy, learning. The subject was speed and in a week's practice he learned more about speed than the fastest gull alive. Time after time it happened. Careful as he was, working at the very peak of his ability, he lost control at a high speed. The key, he thought at last, dripping wet, must be to hold the wings still at high speeds – to flap up to fifty and then hold the wings still. |
| (4) | From two thousand feet he tried again, rolling into his dive, beak straight down, wings full out and stable from the moment he passed fifty miles per hour. It took tremendous strength, but it worked. In ten seconds he had blurred ninety miles per hour. Jonathan had set a world speed record for seagulls! But victory was short-lived. The instant he began his pullout, the instant he changed the angle of his wings, he snapped into the same uncontrollable disaster, and at ninety miles per hour, it hit him like dynamite. Jonathan Seagull exploded in midair and smashed down into a brick-hard sea. As he sank low in the water, a strange hollow voice sounded within him. There's no way around it. I am a seagull. I am limited by my nature. If I were meant to learn so much about flying, I'd have charts for brains. If I were meant to fly at speed, I'd have a falcon's short wings. Short wings. A falcon's short wings! That's the answer! What a fool I've been! All I need is a tiny little wing, all I need is to fold most of my wings and just fly on the tips along. Short wings! |
