Read the following passage and do the activities.
Galaxies are vast clusters of thousands of millions of stars, planets, gases and dust, which are held together by gravity. There are over one thousand million galaxies, and each is a very long way from its nearest neighbour.
Galaxies were formed during the Big Bang explosion about 15,000 million years ago. When this phenomenon occurred, everything that was in the universe flew out in different directions. Scientists believe that the galaxies were formed from lumps of matter that resulted. However, the process is nowhere near complete. The universe is still expanding, galaxies are still moving away from each other, new stars are still being created.
Galaxies are classified according to their shapes. There are three main types. The most common type of galaxy is The Spiral. This has several spiral arms radiating out from the center. Spiral galaxies have a large cluster of stars in their nucleus. The second type is the Barred spiral. In this type of galaxy, the spiral arms curve away from the opposite ends of a sort of bar going through the middle of the nucleus. These contain large amounts of gas and dust as well stars. The third type of galaxy is electrical. These consist almost entirely of stars and contain very little gas or dust. Some galaxies have irregular, uneven shapes and cannot be classified.
(A1) State whether the following statements are true or false. 02
(1) The most common type of galaxy is the barred spiral.
(2) Galaxies are clusters, held by gravity.
(3) Scientists do not believe in the Big Bang explosion.

(A5) Any reasonably correct answer written in 4-5 sentences.
(B) Galaxies
Galaxies are stars, planets, gases and dust held together by gravity. There are over 1000 million galaxies in the universe, and there is a vast distance between them. Galaxies were formed when the Big Bang explosion took place 15,000 million years ago. Things in the universe flew out in different directions, forming lumps of matter or galaxies. The process is still on and the universe continues to expand. Galaxies can be classified into spiral, barred spiral and elliptical. Spiral galaxies have spiral arms from the nucleus. The nucleus has a large cluster of stars. Barred spiral galaxies have arms from the opposite ends of a bar across the nucleus and contain a large amount of gas, dust and stars. Elliptical galaxies are made up of mostly stars, and have very little gas or dust.

Read the passage given below :
Kausani is situated at a height of 6,075 feet in the Central Himalayas. It is an unusally attractive little town. It covers just about 5.2 sq. kms. It lies to the north of Almora in Uttarakhand's picturesque kumaon region.
Kausani provides the 300-km wide breathtaking view of the Himalayas. It is the most striking aspect of the place. Snow-capped peaks are spread in a stately row. They stare at you in silvery white majesty. The most famous peak on view is Nanda Devi, the second highest mountain in India. It is situated at a height of 25.645 feet and 36 miles away as the crow files. The other famous peaks on view are choukhamba (23,420 feet) and Trishul (23,360 feet). Then there are also Nilkanth, Nandaghunti, Nandaghat and Nandakot. On a clear day, the blue of the sky makes a splendid background to these peaks. At sunrise and at sunset, when the colour changes to a golden orange, the scene gets etched in your memory.
When Gandhiji visited this place in 1929, its scenic beauty held him spellbound. He named it the 'Switzerland of Indian'. He prolonged his two-day stay to fourteen days, making time to write a book, 'Anashakti Yoga'. The place where he was staying was originally a guest-house of the tea estate. It was renamed 'Anashakti Ashram' after the book.
Kausani is the birthplace of Sumitranandan Pant, India's poet laureate. Its natural surroundings inspired many of his poems. Its tea gardens mingle with dense pine forests and fruit orchards. The area is also host to many fairs and religious caremonies. If Uttaranchal is the abode of gods, Kausani is God's own backyard. There is no traffic, no one is in a hurry. If serenity could be put on a canvas, the picture would resemble Kausani.
On the basis of your reading of the above passage, answer the following questions :
(a) Where is Kausani situated ?
(b) What is the most striking aspect of Kausani ?
(c) Which is the most famous peak on view from Kausani ?
(d) How did Kausani influence Sumitranandan Pant ?
(e) When does the view of peaks become so memorable ?
(f) How can we say that Gandhiji was greatly charmed by the natural beauty of Kausani ?

Read the following extract and answer the questions given below:
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 1·3 million billion would the earth be too hot to be habitable. And though it would feel like being ina 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 worldwide. Though the population has grown, the rate of growth has fallen sharply. Twenty years ago, the UN projected that the population would reach 11·I6 billion in 2050, today they say it will reach only 9·3 billion. Moreover, the 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 the 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?
(2) How does the writer explain that fertility is on the decline?
(3) What does the extract predict about the fear of scarcity of food?
(4) How will the population become a gift in the global market scene?
(5) Rewrite the following sentences in the ways instructed:
(i) The earth could withstand up to 200,000 times the current population.
(Rewrite the sentence using the modal auxiliary showing 'certainty'.)
(ii) The earth would be too hot to be habitable.

(iii) These resources are being used.

Read the extract and complete the activities given below :
Luxurious houses on the edge of a big city which one promoter sold with the tagline ‘‘Where Nature peeps through every window.’’ All the advantages of a modern lifestyle but with the added bonus of fresh air. But nature isn’t greenery alone; it also includes wild animals.
While the view from the picture windows was easy on the eye, occasionally, it made them gulp with nervousness. At dusk, wild cats leaped out of the adjoining forest on to the top of the peripheral walls and strolled nonchalantly. Sometimes, they lounged on ledges with their long tails swinging freely, oblivious of the many worried human eyes pinned on them. Their cold yellow aggressive eyes turned black as their pupils dilated with failing light.
Some Mumbaikars paid a lot of money to see leopards on safari in Africa. But to watch them from one’s own home was disconcerting. These predators were out of line, stepping off nature into the city. Why did the leopards not stay within the 100-square kilometre Sanjay Gandhi National Park? Perhaps, the leopards thought that if people could venture into nature to jog, walk and picnic, why couldn’t they hang around apartment blocks? If people could enjoy nature, couldn’t nature savour humanity’s offerings?
Capturing leopards is extraordinarily simple. These curious cats seem incapable of resisting a free meal, walking into baited traps without hesitation. The reason the felines are attracted to their residential community is prey : stray dogs that live on rubbish heaps. Taking care of the food source is the best course of action, the volunteers said.
A1. Rewrite the following sentences as per their occurrence in the extract :
- Instead of capturing leopards we can take care of their food.
- Leopards leave their habitat and enter the human habitat.
- Modern lifestyle and nature both attract the dwellers.
- Leopards can enjoy human surroundings by leaving nature.
A2. Complete the following sentences :
- Nature is a combination of ______ and ______
- The best of both the worlds include ______ and ______
- The wild animals are out of line as ______
- The wild cats are attracted towards residential areas because ______

A5. Rewrite the following sentences in the ways instructed :

(Use infinitive form of the underlined word and rewrite.) -
Nature isn’t greenery alone; it also includes wild animals.

- ______ and ______ are the qualities of a humorous person.

You are endowed with certain naughtiness as a child. Keep it alive. Humour will lighten all tough situations. One who has humour can sail through any conflict. Humour is buffer that saves you from humiliation. Humour brings everyone together, while humiliation tears them apart. In a society tom with humiliation and inSult, humour is like a breath of fresh air. Humour should be coupled with care and concern. Humour can keep the spirit high, yet if overdone, it leaves a bad taste. Humour without wisdom is shallow. Humour without sensitivity is satire-it comes back to you with more problems. The wise use humour to bring wisdom and to lighten situations. The intelligent use humour as a sword to insult others. The irresponsible use humour to escape from responsibility. And fools take humour too seriously! How does one cultivate a sense of humour? Humour is not just words, it is the lightness of your being. You do not have to read and repeat jokes. Humour can be cultivated by taking life not too seriously (because you will never come out of it alive), having a sense of belonging with everybody, including those who are not friendly, practising Yoga and meditation, having unshakable faith in the Divine and in the laws of Karma, being in the company of those who live in knowledge and have a sense of humour. |

Read the following passage and answer the questions that follow:
| 1. |
Too many parents these days can't say no, As a result, they find themselves raising 'children' who respond greedily to the advertisements aimed right at them. Even getting what they want doesn't satisfy some kids; they only want more. Now, a growing number of psychologists, educators, and parents think it's time to stop the madness and start teaching kids about what's really important: values like hard work, contentment, honesty, and compassion. The struggle to set limits has never been tougher and the stakes have never been higher. One recent study of adults who were overindulged as children paints a discouraging picture of their future: when given too much too soon, they grow up to be adults who have difficulty coping with life's disappointments. They also have a distorted sense of entitlement that gets in the way of success in the workplace and in relationships. |
| 2. |
Psychologists say that parents who overindulge their kids set them up to be more vulnerable to future anxiety and depression. Today's parents themselves raised on values of thrift and self-sacrifice, grew up in a culture where no was a household word. Today's kids want much more, partly because there is so much more to want. The oldest members of this generation were born in the late 1980s, just as PCs and video games were making their assaults on the family room. They think of MP3 players and flat-screen TV as essential utilities, and they have developed strategies to get them. One survey of teenagers found that when they crave something new, most expect to ask nine times before their parents give in. By every measure, parents are shelling out record amounts. In the heat of this buying blitz, even parents who desperately need to say no find themselves reaching for their credit cards. |
| 3. |
What parents need to find, is a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving, and working hard to achieve goals. That search for balance has to start early. Children need limits on their behaviour because they feel better and more secure when they live within a secure structure. |
| 4. |
Older children learn self-control by watching how others, especially parents act. Learning how to overcome challenges is essential to becoming a successful adult. Few parents ask kids to do chores. They think their kids are already overburdened by social and academic pressures. Every individual can be of service to others, and life has meaning beyond one's own immediate happiness. That means parents eager to teach values have to take a long, hard look at their own. |
Based on your understanding of the passage, answer any eight questions from the nine given below:
- What is challenging for today's parents?
- What will be the consequence of over indulging children?
- Why do parents get caught in the buying blitz?
- How do children learn critical life lessons?
- What is the impact of advertisements on children?
- Why do children need limits on their behaviour?
- How do older children learn self-control?
- Find a word in the passage which means 'research'. (Paragraph 2)
- Find a word in the passage which means 'wealthy'. (Paragraph 3)
Read the extract given below:
| (1) | Necessity is indeed the mother of invention. When areas in and around Leh began to experience water shortages, life didn't grind to a halt. Why? Because a retired civil engineer in the Jammu and Kashmir Government came up with the idea of artificial glaciers. |
| (2) | Ladakh, a cold desert at an altitude of 3,000 - 3,500 meters above sea level, has a low average annual rainfall rate of 50 mm. Glaciers have always been the only source of water. Agriculture is completely dependent on glacier melt, unlike the rest of river/monsoon-fed India. But over the years, with increasing effects of climate change, rainfall and snowfall patterns have been changing, resulting in severe shortage and drought situations. Given the extreme winter conditions, the window for farming is usually limited to one harvest season. |
| (3) | It is located between the natural glacier above and the village below. The one closer to the village and lowest in altitude melts first, providing water during April-May, the crucial sowing season. Further, layers of ice above melt with the increasing temperature, thus ensuring continuous supply to the fields.
Therefore, farmers have been able to manage two crops instead of one. It costs about 1,50,000 and above to create a glacier. |
| (4) |
Fondly called the glacier man, he has designed over 15 artificial glaciers in and around Leh since 1987. In recognition of his pioneering effort, he was conferred the Padma Shri by The President of India. |
| (5) |
There are a few basic steps followed while creating an artificial glacier. River or stream water at high altitude is diverted to a shaded area of the hill, facing north, where the winter sun is blocked by a ridge or a mountain range. At the start of winter ie., in November, the diverted water is made to flow on sloping hills facing distribution channels. Stone embankments are built at regular intervals which impede the flow of water, making shallow pools which freeze, forming a cascade of ice along the slope. Ice formation continues for 3-4 months resulting in a large accumulation of ice which is referred to as an ‘artificial glacier’. |
Based on your understanding of the extract, answer the questions below:
- Infer one reason for, the following, based on information in paragraph 1. (1)
