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.

One of the greatest advances in modern technology has been the invention of computers. They are widely used in industries and in universities. Now there is hardly any sphere of human life where computers have not been pressed into service of man. We are heading fast towards the day when a computer will be as much part of man's daily life as a telephone or a calculator.
Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic jams. This whole process by which machines can be used to work for us has been called 'automation'. In the future 'automation' may enable human beings to enjoy more leisure than they do today. The coming of automation is bound to have important social consequences.
Some years ago an expert on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could 'think'. There is no possibility that human beings will be "controlled by machines". Though computers are capable of learning from their mistakes and improving on their performance, they need detailed instructions from human beings to operate. They can never, as it were, lead independent lives or "rule the world" by making decisions of their own.
Sir Leon said that in future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions. Car drivers can be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications.

Read the passage given below.
Then all the windows of the grey wooden house (Miss Hilton used to live here. She expired last week.), were thrown open, a thing I had never seen before.
At the end of the day a sign was nailed on the mango tree: FOR SALE.
Nobody in the street knew Miss Hilton. While she lived, her front gate was always locked and no one ever saw her leave or saw anybody go in. So even if you wanted to, you couldn't feel sorry and say that you missed Miss Hilton.
When I think of her house I see just two colours. Grey and green. The green of the mango tree, the grey of the house, and the grey of the high iron fence that prevented you from getting at the mangoes.
If your cricket ball fell in Miss Hilton's courtyard you never got it back. It wasn't the mango season when Miss Hilton died. But we got back about ten or twelve of our cricket balls.
The house was sold and we were prepared to dislike the new owners ever before they came. I think we were a little worried. Already we had one resident of the street who kept on complaining about us to our parents. He complained that we played cricket on the pavment; and if we were not playing cricket he complained that we were making too much noise anyway.
One afternoon, when I came back from school Pal, said, "Is a man and a woman. She pretty pretty, but he ugly like hell". I didn't see much. The front gate was open, but the windows were shut again. I heard a dog barking in an angry way.
One thing was settled pretty quickly. Whoever these people were they would never be the sort of people to complain that we were making noise and disturbing their sleep.
A lot of noise came from the house that night. The radio was going at full volume until midnight when the radio station closed down. The dog was barking and the man was shouting. I didn't hear the woman.

(a) Nobody went into Miss Hilton's house because her front __________.
(b) Her house had only two colours, (i) __________ and (ii) __________.

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. |
|
15
|
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. |
|
20
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. |

- 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.

November 4, 1851. Dear Brother John Honston, When I came to Charleston day before yesterday, I learned that you were anxious to sell the land where you live, and move to Missouri. I have been thinking of this ever since, and cannot but say such an idea is quite foolish. What can you do in Missouri better than here? Is the land any richer? Can you, there, any more than here, raise com and wheat without work? Will anybody there, any more than here, do your work for you? If you intend to go to work, there is no better place than right where you are; if you do not intend to work, you cannot get along anywhere. Crawling about from place to place can do you no good. You have raised no crop this year. What you really want is to sell the land, get the money and spend it. Part with the land you have and my life upon it-never after will you own a spot big enough to bury you. Half of what you will get for the land, you will spend in moving to Missouri, and the other hall you will eat, drink, wear out and no foot of land will be brought. Now I feel it my duty to have no hand in such a piece of foolery. Now do not misunderstand this letter. I do not write it in any unkindness. I write it in order, if possible, to get you to face the truth which truth is, you are poor and needy because you have idled away your time. Your thousand excuses for not getting along better are all nonsense. They deceive nobody but yourself. To go to work is the only cure for your case. Affectionately, |

- Vegetarianism has not spread as desired because ______.
- Vegetarians are of various types ______.
|
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 soul. Thus, an item of food which 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. |

How bird hits happen, why they are a concern? New Delhi June 20 At least two bird strike incidents happened on Sunday. Both aircrafts returned to their airports of origin and were grounded for maintenance. An ABC aircraft, which took off from Guwahati towards Delhi, suffered damage to its left engine following a bird hit at 1600 feet. The pilots returned to Guwahati. The other strike happened on another flight from Patna to Delhi. The pilots of the aircraft suspected a bird strike during the take-off roll but continued to climb. Following the take-off rotation, they were informed by the cabin crew of sparks emanating from the left engine. Subsequently, the pilots were also informed by air traffic control of smoke coming out of one of the engines. The pilots declared an emergency and returned to Patna. |
| (2) |
Why are bird strikes a concern? Bird strikes are among the most common threats to aircraft safety, and they typically occur during take-off or landing. Dozens of bird-strikes happen each day but some can be more dangerous than others. Typically, when birds collide with an aircraft's airframe, it is unlikely to cause significant problems for the pilots flying. But there are instances when the aircraft engine ingests the birds. This can lead to a loss of thrust for the engine and cause manoeuvrability problems for the crew. In these cases, where a jet engine ingests a bird, procedures would generally call for pilots to land the plane at the closest airport. While most airframe bird strikes are not considered critical to air safety, if a collision cracks a window or a wind screen, pilots will look to land as early as possible. |
| (3) |
How critical are bird strikes to air safety? Smaller planes would generally be more susceptible to the dangers of bird strikes than larger ones. However, given that bird strikes mostly happen during take-off and landing, these incidents could distract the pilots during what are highly critical phases of flights that demand the complete attention of the crew. |
| (4) |
What causes bird-strikes? The presence of birds around an aircraft increases the chances of a bird strike. In the monsoon, as water puddles emerge on open grounds attracting insects to breed, the presence of birds increases. In some cases, bird hits also happen at higher altitudes when a plane is cruising. These are more dangerous than the low-altitude hits, given that they can cause rapid depressurization of cabins. Other reasons for bird activity around the airfield could be presence of landfills or waste disposal sites that can attract a large number of birds. |
- Does the following statement agree with the information given in paragraph 1? (1)
When an airplane is hit by a bird or is suspected to have been hit, the passengers must be asked to get down at once.
Select from the following:
True: If the statement agrees with the information.
False: If the statement contradicts the information.
Not Given: If there is no information on this. - Select the option that displays the most likely reason for bird hits. (1)

Smaller planes are generally more ______ than larger ones. - Complete the sentence by selecting the most appropriate option: (1)
When the window or the windscreen of the airplane is cracked due to a bird hit ______.- the crew must rush to the cockpit
- the pilot must land at the earliest airport
- the pilot must inform the maintenance engineer
- the pilot must get instructions from the aviation wing on what should do in emergency
- Based on the reading of the text, state a point to further the statement. (1)
Dozens of bird hits take place every day ______.
- but only a few are dangerous
- all of them are fatal
- but after every bird hit it is imperative to land the aircraft
- the pilot should ignore them
- Complete the sentence based on the following statement: (1)
Complete attention of the crew is demanded during take-off and landing.
We can say this because ______. - Complete the sentence appropriately with one/two words. (1)
In cases where the aircraft engine infests the bird, it leads to the loss of thrust and causes problems in ______. - Which are the areas more prone to bird hits? (1)
- Based on the reading of the text, state a point to challenge the given statement: (1)
The area around air fields should be clear of any waste disposal sites. - Look at the graph. It shows that between 2016 and 2021, whereas air flights have come down, the bird-hits have gone up. This implies that the incidence of bird hits has: (1)
- decreased
- increased
- remained constant
- been alarming
