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. |
A2. Write two reasons for the conservation of fireflies. (2)
A3. Make antonyms of the following words using prefix: (2)
- different × ______
- experience × ______
- bacterial × ______
- natural × ______
A4. Do as directed: (2)
(i) Too many people can disturb adult and larval habitat.
(Rewrite using 'as well as')
(ii) These react together to produce photons.
(Pick out the infinitive from the given sentence)
A5. Can you think of any other insect that teaches us some values of life? Explain with examples. (2)
Solution
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.

Gandhiji As a Fund Raiser
Gandhiji was an incurable and irrestible fund raiser. He found special relish in getting jewellery from women. Ranibala of Burdwan was ten years old. One day she was playing with Gandhiji. He explained to her that her bangles were too heavy for her delicate little wrists. She removed the bangles and gave them away to Gandhiji.
He used to talk jokingly to small girls and created distaste for ornaments and created a desire in them to part with the jewellery for the sake of the poor. He motivated them to donate their jewellery for social usage.
Kasturbai didn’t appreciate this habit of Gandhiji. Once she stated calmly, ‘You don’t wear jewels, it is easy for you to get around the boys. But what about our daughters-in-law ? They would surely want them.
“Well!” Gandhiji put in mildly, "our children are young and when they grow up they will not surely choose wives who are found of wearing jewellery.” Kasturbai was very upset with the answer.
Gandhiji was determined to keep the jewels to raise community fund. He was of the opinion that a public worker should accept no costly gifts. He believed that he should not own anything costly, whether given or earned. Kasturbai was a female with a desire to adorn. But Gandhiji moved towards renunciation and donated every penny earned in South Africa to the trustees for the service of South African Indians.

Read the following extract and answer the questions given below:
There are some glimmers of hope. I met up young Navdeep. Ahuja who along with another colleague began the innocuously named Graduates Welfare Association, Fazilka. They are bringing about change with the mandate of citizens' participation in governance and are facilitating the creation of physical and social infrastructure across 22 cities in Punjab. They have put in place a network of cycle rickshaws called Eco-cabs which can be booked through a mobile phone. They are also developing car tree zones, food and culture streets in these cities. All this is being done very efficiently and at a low cost. We need many such organizations. However, my idea of a city in 2020 is not a utopian dream. It is achievable. It has streets where people walk on wide footpaths shaded by leafy trees. Streets are usually one-third of a city's area and its most democratic segment. Public space dedicated to pedestrians reduces inequality and should be accorded priority when developing cities. Adjoining the streets should be cycle lanes where bicycles and, rickshaws can sail past smoothly. It'll have a great public transport system with buses, metro and taxis. Parking will be difficult and expensive so people will use public transport rather than cars. There will be parks and gardens and the air will be clean, as pollution levels will have dropped dramatically. And then cities will become areas of graceful living and a charmed way of life.

“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
remind me of what I have lost .

A1. List the benefits of Yoga (02)
- ______
- ______
- ______
- ______
We give undue importance to our health and the treatment of diseases. A large number of medicines treat only the symptoms of the disease, and not the root cause. In fact, the cause of many chronic ailments is still being researched. It is here that Yoga therapy comes to our assistance. Yoga emphasizes the treatment of the root cause of an ailment. It works in a slow, subtle and miraculous manner. Modern medicine can claim to save a life at a critical stage, but, for complete recovery and regaining of normal health, one must believe in the efficiency of Yoga therapy.
The Yogic way of life includes a code of ethics, regulations, discipline, combined with prayer and meditation. Even a discussion of these subjects helps one relieve mental tensions and change attitudes. Simple Asana has helped to stretch and relax the whole body and release tensions. The sincere practice of Yoga postures is beneficial, for the mind and body.
The continued practice of Yoga has a profound effect on the inner dimensions of life. Yoga aims at developing mental, physical, spiritual, and emotional facilities. Other forms of physical exercises, like aerobics, assure only physical well-being. They have little to do with the development of the soul and mind.
A2. Complete the following statement according to the passage: (02)
- One must believe in the ________
- Aerobics assure only __________
A3. Fill up the word-formation chart: (02)

1. The Higgs boson has been called, or miscalled, the God particle, enabling it to pass into the realm of popular scientific lore, like the discovery of the smallpox vaccine, the structure of DNA, or the theory of relativity. It would be difficult for most people to understand its significance, just as it would be to comprehend the notion of relativity, but such problems are overcome by locating science in personalities as well as cultural and national traditions. The first thing that you and I know about the Higgs boson is that it’s named after Peter Higgs, a physicist at Edinburgh University who made the discovery - although the original insight, in one of those recurrent back stories of science, was Philip Anderson’s. 2. Still, we have Higgs, and Edinburgh, and western civilisation to fall back on. The rest - “the Higgs boson is a hypothetical elementary particle predicted by the Standard Model of particle physics. It belongs to a class of particles known as bosons ...” - we needn’t worry too much about. But maybe we should worry just enough to ask, “What is a boson?” since the word tends to come up as soon as Higgs does. Is it, an ignoramus such myself would ask, akin to an atom or a molecule? It is, in fact, along with the fermion (named after Enrico Fermi), one of the two fundamental classes of subatomic particles. 3. From Bose The word must surely have some European genealogy. In fact, “boson” is derived from Satyendra Nath Bose, an Indian physicist from Kolkata who, in 1924, realised that the statistical method used to analyse most 19th-century work on the thermal behaviour of gases was inadequate. He first sent off a paper on quantum statistics to a British journal, which turned it down. He then sent it to Albert Einstein, who immediately grasped its immense importance, and published it in a German journal. Bose’s innovation came to be known as the Bose-Einstein statistics and became a basis of quantum mechanics. Einstein saw that it had profound implications for physics; that it had opened the way for this subatomic particle, which he named, after his Indian collaborator, “boson.” Still, science and the West are largely synonymous and coeval: they are words that have the same far-reaching meaning. Just as Van Gogh and Toulouse-Lautrec’s paintings digest the Japanese prints they were responding to so we don’t need to be aware of Japanese prints when viewing the post-impressionists, western science is pristine, and bears no mark of what’s outside itself. 4. Other Indian contributions The last Indian scientific discovery that is universally acknowledged is zero. Indians are very strong at maths, and the only modern Indian who’s remotely part of the western mythology of science is Srinivasa Ramanujan, equally well known for his Hindu idiosyncrasies and his agonised stay in Cambridge as he is for his mathematical genius. 5. Indians can be excellent geeks, as demonstrated by the tongue-tied astrophysicist Raj Koothrappalli in the U.S. sitcom Big Bang Theory; but the Nobel prize can only be aspired to by Sheldon Cooper, the super-geek and genius in the series, for whom Raj’s country of origin is a diverting enigma, and miles away from the popular myth of science on which Big Bang Theory is dependent. Bose didn’t get the Nobel Prize; nor did his contemporary and namesake, J.C. Bose, whose contribution to the fashioning of wireless predates Marconi’s. The only Indian scientist to get a Nobel Prize is the physicist C.V. Raman, for his work on a light at Kolkata University. Other Indians have had to become Americans to get the award. 6. Conditions have always been inimical to science in India, from colonial times to the present day; and despite that, its contributions have occasionally been huge. Yet non-western science (an ugly label engendered by the exclusive nature of western popular imagination) is yet to find its Rosalind Franklin, its symbol of paradoxical success. Unlike Franklin, however, scientists were never in a race that they lost; they simply came from another planet. |

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 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! |
