A1. Complete the chart on the life stages of fireflies: (2)
|
Fireflies are beetles and go through several life stages, starting out as an egg, then hatching into larvae. At the juvenile stage, they turn into pupae and then, finally adults. Fireflies spend most of their lives in a larval stage, hidden away. There are 2000 different species of fireflies. But they all go through a long juvenile stage and a short adult life, which is mainly about courtship, mating and reproduction. The juveniles living underground or underwater, are very different though-they're hunters, they eat snails and soft-bodied insects and they have very different habitats. Conserving them is essential for human life as fireflies are a key part of the food web. They are predators of agricultural pests. In turn, they are prey for spiders and other insects. They are completely enmeshed in the web of life. In addition, about 70 years ago, scientists unravelled the mystery of fireflies' light-producing talents. Since then, the bio-chemical reactions that fireflies experience have been used in detecting bacterial contamination in foods, testing drugs against cancer, developing drought-resistant crops. They have been used in space exploration. So fireflies give us beauty and inventions. Fireflies carry oxygen, calcium, magnesium and a natural chemical called luciferin. These react together to produce the photons. This is how the fireflies glow. Firefly tourism is growing across the world. In Maharashtra, for example, a particular species monsoon fireflies, emerge before the rains. They're beautiful and a festival is held in Purushwadi, encouraging firefly tourism. Its wonderful that people around the world go to see fireflies in their natural habitat. We need to be cautious. Too many people can disturb adult and larval habitats. Fireflies need darkness to communicate with each other and we need fireflies because they are harbingers of hope. |

उत्तर
A1.
A2. Fireflies are preserved because the biochemical processes they go through are important for detecting bacterial contamination in food and testing anti-cancer medications, among other things. Oxygen, calcium, magnesium, and luciferin are also carried by fireflies.
A3.
- different × indifferent
- experience × inexperience
- bacterial × anti-bacterial
- natural × unnatural
A4. (i) Many people can disturb adult as well as larval habitat.
(ii) to produce
A5. Insect pollinators, such as bees, help with propagation and fruit production. They are also pest predators or parasites. Aside from that, they provide honey. Bees work extremely hard. They frequently work themselves to death. This is a source of inspiration for humans. They teach us to never give up, even when the odds are stacked against us.

Read the following extract and answer the questions given below :
Early risers clearly have the edge in life. By the time most of us wake up, they've been through their morning rituals, enjoyed their walk, had their tea and read the daily news. They're also likely to have made long-distance calls before dawn to those similarly inclined. Thus, by the time the sun warms up they're likely to have discussed all varieties of 'men, matters, and affairs' with a dozen people.
The upshot of these varying tendencies is that such extreme contrasts often exist in the same household. Weeks pass before the younger lot (typically late risers) and the older lot (normally early birds) come face to face. It's almost as if they live in different time zones and different countries.
All over the country, things are likely to be pretty much the same in this respect, one would think. If the man of the house, any house, decides to take a day off from work, he'd probably find his son emerging from his room at about I0 a.m. and that too in a 'rubbing-eyes' mode. After fooling around for a while the lad would probably dash off to college in a rush whilst simultaneously zipping up his jeans and sending text messages on his phone. His father would undoubtedly be left shaking his head and burying himself deeper into his newspaper.
(1) What is the extract about?
(2) How do the early risers get a headstart in life?
(3) What kind of lifestyle of the young son is reflected in the extract?

Read the following extract and answer the questions given below.
|
I grew up in India in which telephones were both rare and virtually useless. When I left India in 1975 to go to the US for graduate studies, we had perhaps, 600 million residents in the country and just two million landline telephones. Having a telephone was a rare privilege: if you weren’t an important government official, or a doctor, or a journalist, you might languish in a long waiting list and never receive a phone.
Telephone were such a rarity (after all, 90% of population had access to a telephone line) that elected members of Parliament had amongst their privileges the right to allocate 15 telephone connections to whomever they deemed worthy.
And if you did have a phone, it wasn’t necessarily a blessing. I spent my high school years in Calcutta, and I remember that if you picked up your phone, you had no guarantee you would reach the number you had dialled. Sometimes you were connected to someone else’s ongoing conversation, and they had no idea you were able to hear them; there was even a technical term for it, the ‘cross - connection’ (appropriately, since these were connections that made us very cross). If you wanted to call another city, say Delhi, you had to book a ‘trunk call’ in the morning and then sit by the telephone all day waiting for it to come through; or you could pay eight times the going rate for a ‘lightning call’ = but even lightning struck slowly in India those days, so it only took half an hour instead of the usual three or four or more to be connected.

Read the passage given below :
Globalization
Globalization is the way to open businesses, improve technological growth, economy, etc, at the international level for all countries. It is the way in which manufacturers and producers of the products or goods sell their products globally without any restriction. It provides huge profits to the businessmen as they get 1ow cost labor in poor countries easily. It provides a big opportunity for companies to„ deal with the worldwide market.
Globalization helps to consider the whole world 'as a single market. Traders are extending their areas of business by treating the world as a global village. Earlier till the 1990s, there was a restriction on importing certain products that were already manufactured in India like agricultural products, engineering goods, food items, and toiletries. However, during the 1990s there was pressure from. the rich countries on the poor and developing countries to allow them to spread their businesses by opening their markets. In India, the globalization and liberalization process was started in 1991.
After many years, globalization brought about a major revolution in the Indian market when multinational brands came to India and started delivering a wide range of quality products at cheap prices. Prices of good quality products came down because of the cutthroat competition in the market.
Globalization and liberalization of the businesses in India have flooded the market with quality foreign products but have affected the local Indian industries adversely to a great extent resulting in job loss to poor and uneducated workers. Globalization has been a bonanza for the consumers, however, a loss to the small-scale Indian producers.
Globalization has had some very positive effects on the Indian consumer in all sectors of society. It has affected the Indian students and education sector to a great extent by making study books and a lot of information available over the internet. The collaboration of foreign universities with Indian universities has brought about a huge change in the field of education.
Globalization of trade in the agricultural sector has brought varieties of quality seeds that have disease resistati8e; property. However, it is not good for the poor Indian farmers because the seeds and agricultural technologies are costly.
It has brought about a huge revolution in the employment sector by the spread of businesses like cottage, handloom, carpet, artisan carving, ceramic, jewelry, and glassware, etc

(b) Write any two advantages of globalization.
(c) What was the pressure from the rich countries in the 1990s?
(d) What is the effect of multinational brands entering the Indian market?
(e) How are the prices of quality products affected due to globalization?

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.

I saw ‘Jaws’, the popular shark movie, the summer it came out, in 1975 and became paranoid about sharks. Though I kept swimming after Jaws, it was always with the vague fear that a shark’s teeth could tug on my leg at any moment. Never mind that there’d been only two shark bites since 1900 on the Connecticut coast, where I lived. |
| 10 | So, when I got this assignment for the National Geographic magazine, I decided to accept and do what I’d never wanted to do: swim with the sharks. I had to go to a place in the Bahamas known as Tiger Beach and dive with tiger sharks, the species responsible for more recorded attacks on humans than any shark except the great white. It was to be my first dive after getting certified-which meant it would be my first dive anywhere other than a swimming pool or a quarry-and without a diver’s cage. Most people who got wind of this plan thought I was either very brave or very stupid. |
|

But I just wanted to puncture an illusion. The people who know sharks intimately tend to be the least afraid of them, and no one gets closer to sharks than divers. The divers who run operations at Tiger Beach speak lovingly of the tiger sharks and the way people talk about their children or their pets. In their eyes, these sharks aren’t man-eaters any more than dogs are. |
|

25 |
The business of puncturing illusions is never just black and white. My fellow divers had hundreds of dives under their belt and on the two-hour boat ride to the site on the morning of our first dive, they kept saying things like, “Seriously, I really can’t believe this is your first dive.” All this was okay with me until I reached the bottom and immediately had to fend off the first tiger shark, I had ever laid eyes on. However, when I watched the other divers feeding them fish and steering them gently, it became easy to see the sharks in a very benign light. |
| 30 | I think it would be unfair not to mention that tiger sharks are apex predators. They act as a crucial balancing force in ocean ecosystems, constraining the numbers of animals like sea turtles and limiting their behaviour by preventing them from overgrazing the seagrass beds. Furthermore, tiger sharks love warm water, they eat almost anything, have a huge litter and are the hardiest shark species. If the planet and its oceans continue to warm, some species will be winners and others will be losers, and tiger sharks are likely to be winners. |
Based on your understanding of the passage, answer the questions given below.
- Cite a point in evidence, from the text, to suggest that the writer's post-Jaws fear was not justified.
- State any one trait of the writer that is evident from lines 5-10 and provide a reason for your choice.
- People thought the writer was ‘either brave or very stupid’. Why did some people think that he was ‘very stupid’?
- Why does the writer say that people who know sharks intimately tend to be least afraid of them?
- Rewrite the given sentence by replacing the underlined phrase with another one, from lines 10-20.
Some academicians think that reward, as a form of discipline, is a simple right or wrong issue. - What does the use of the phrase ‘benign light’ suggest in the context of the writer’s viewpoint about tiger sharks?
- Select a suitable phrase from lines 15-25 to complete the following sentence appropriately.
I agree the team will find this experience tough, but competing will be easier next time after they get this tournament ______ - Apex predators serve to keep prey numbers in check. How can we say that tiger sharks are apex predators?
- Analyse why having a large litter is one of the features that empower tiger sharks to emerge, winners, if global warming persists.

Vegetarianism promotes a natural way of life. But despite its implicit message of universal love and nonviolence, it has not spread as it should have. This may be because it usually is an inward looking habit and is best cultivated in the mind. Leading a vegetarian way of life helps the animal kingdom to coexist with man. The animals supply milk, manure and energy. This has been central to Indian culture for thousands of years. A vegetarian lifestyle is natural, multifaceted and helps preservation in a healthy way. Food and health are closely related. Vegetarians are of various types. There are lacto-vegetarians who consume dairy products; Lacto-ovo-vegetarians include eggs in addition to dairy products. Vegans are pure vegetarians who do not consume any food derived from animals. The Western science of food considers food as something to sustain only the human body, whereas Indian science considers food as something which sustains not only the body but also maintains the purity of heart, mind and the soul. Thus, an item of food that is injurious to the mind is not considered to be fit for consumption, even if it is otherwise beneficial to the body or satisfies the taste. Indian food science does not give so much importance to protein or even to a balanced diet but it gives importance to food that increases the strength of the body and its vitality. Vegetarian foods provide an infinite variety of flavours whereas non-vegetarian foods have hardly any taste of their own. In fact, non-vegetarian foods have to be seasoned with ingredients from the vegetable kingdom to make them palatable. |
