Question
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.

Nicholas chorier is not your usual photographer. He is a kite aerial photographer. He uses a kite to hoist his camera into the skies and clicks photographs while the camera dangles precariously mid – air.
As a teenager, Nicholas had two passions – photography and kite flying. During’ a trip to India to make a photo report on kite making, he learnt about this unique style of photography. Fascinated, he literally tied his two hobbies together for a living.
Nicholas learnt to make a strong modelled on the Japanese kites, Rokkaku that could endure harsh winds. A novice in his chosen field, he then set out to train himself. Today he is one of the most well – known aerial photographers in the world.
The technique is to tie a cradle containing the photography equipment to the string of the kite and then fly it, thus launching the camera into air. From the ground, Nicholas manipulates the angles of the camera with a remote. An air – to – ground video link enables him to see the view from the kite’s vantage point. Once satisfied with the frame, he clicks a picture.
However, the job does have its pitfalls too. Once, his kite disappeared in the Yamuna river, with his expensive camera in tow.
He is especially fond of India, having made a couple of trips and taken many spectacular photos. “India is too vast and beautiful a country to be captured through the lenses in one life” he says.
He recently released a book, Kite’s Eye View: India between Earth and sky. Though it includes photographs of oft takes sites like the Taj Mahal, it shows them from a totally different perspective.

Read the passage given below and answer the questions that follow:
If you are addicted to coffee, and doctors warn you to quit the habit, don’t worry and just keep relishing the beverage, because it’s not that bad after all! In fact, according to a new study, the steaming cup of Java can beat fruits and vegetables as the primary source of antioxidants. Some studies state that coffee is the number one source of antioxidants in American diet, and both caffeinated and decaf versions appear to provide similar antioxidant levels.
Antioxidants in general have been linked to a number of potential health benefits, including protection against heart diseases and cancer, but Vinson, a dietitian said that their benefits ultimately depend on how they are absorbed and utilized in the body. The research says that coffee outranks popular antioxidant sources like tea, milk, chocolate and cranberries. Of all the foods and beverages studied, dates actually have the most antioxidants based solely on serving size, but since dates are not consumed anywhere near the level of coffee, the drink comes as the top source of antioxidants, Vinson said.
Besides keeping you alert and awake, coffee has been linked to an increasing number of potential health benefits, including protection against liver and colon cancer, type 2 diabetes, and Parkinson’s disease, according to some recently published studies. The researchers, however, advise that one should consume coffee in moderation, because it can make you jittery and cause stomach pains

Read the following extract carefully. (4)
Read the following extract and answer the questions given
below:
Another relative has no plans of joining this league though.
She is rather μnabashed about waking up past noon on a daily basis. To be fair, her husband is a media personality who typically arrives home from work past midnight. That does indeed give them sufficient justification to stay longer in slumber-land each morning. This practice does lead to certain oddities though. He goes for his 'morning' walk at 1 pm, heatwaves and appalled onlookers notwithstanding. They once returned from a night out only to meet the neighbour's son who was off on an early morning jog!
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.
Questions:
(1) What information does the extract give about the typical
routine of a media person?
(2) According to the writer, who are the early risers and the late risers?
(3) Why does the writer say that early risers clearly have the edge in life?
(4) Do you rise early or late? Why?
(5) Rewrite the following sentences in the ways instructed:
- They live in different time zones and different countries.
(Rewrite the sentence using 'not only- but also'.) - That gives them sufficient justification.
(Rewrite the sentence using the Present Perfect tense.) - She is rather unabashed about waking up past noon on a daily basis.
(Rewrite the sentence using 'infinitive' form of
the underlined word.)
(6) Find out from the extract the words which mean:
(i) frightened
(ii) sleep
Read the following extract and answer the questions given below :
Reuben arrived at the factory. The sack buyer was about to lock up.
"Mister! Please don't close up yet." The man turned and saw Reuben, dirty and sweat-stained.
"Come back tomorrow, boy."
"Please, Mister. I have to sell the sacks now-please." The man heard a tremor in Reuben's voice and could tell he was close to tears.
"Why do you need this money so badly?"
"It's a secret."
The man took the sacks, reached into his pocket and put four nickels into Reuben's hand. Reuben murmured a quiet thank-you and ran home.
Then, clutching the tin can, he headed for the store.
"I have the money" he solemnly told the owner, pouring his coins onto the counter.
The man went to the window and retrieved Reuben's treasure. He wiped the dust off and gently wrapped it in brown paper. Then he placed the parcel in Reuben's hands.
Racing home, Reuben burst through the front door. His mother was scrubbing the kitchen range. "Here Mum!Here!" Reuben exclaimed as he ran to her side. He placed a small box in her work-roughened hand.
She unwrapped it carefully, to save the paper. A blue-velvet jewel box appeared. Dora lifted the did, tears beginning to blur her vision.
In gold tettering on a small, almond-shaped brooch was the word 'Mother'
It was Mother's Day, 1946
Dora had never received such a gift; she had no finery except her wedding ring. Speechless, she smiled radiantly and gathered her son into her arms.
(1) Why did Reuben insist on the sack buyer to buy his sacks that day only?
(2) How did the mother react when Reuben gave her the gift?
(3) In what way was Reuben's gift special to his mother?
(4) What do you plan to do on Mother's Day?
(5) Rewrite the following sentences in the ways instructed :
(i) I have to sell the sacks.
(Rewrite it replacing the underlined part with the modal auxiliary showing 'compulsion'.)
(ii) She smiled radiantly and gathered her son into her arms. (Use 'As soon as'.)

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. |

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. |
