Read the following passage and complete the activities:
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:
1. Every morning Ravi gives his brain an extra boost. We're not talking about drinking strong cups of coffee or playing one of those mind-training video games advertised all over Facebook. "I jump onto my stationary bike and cycle for 45 minutes to work," says Ravi. "When I get to my desk, my brain is at peak activity for a few hours." After his mental focus comes to a halt later in the day, he starts it with another short spell of cycling to be able to run errands.
2. Ride, work, ride, repeat. It's scientifically proven system that describes some unexpected benefits of cycling. In a recent study in the Journal of Clinical and Diagnostic Research, scientists found that people scored higher on tests of memory, reasoning, and planning after 30 minutes of spinning on a stationary bike than they did before they rode the bike. They also completed the tests faster after pedalling.
3. Exercise is like fertilizer for your brain. All those hours spent on exercising your muscles, create rich capillary beds not only in leg and hip muscles, but also in your brain. More blood vessels in your brain and muscles mean more oxygen and nutrients to help them work. When you pedal, you also force more nerve cells to fire. The result: you double or triple the production of these cells – literally building your brain. You also release neurotransmitters (the messengers between your brain cells) so all those cells, new and old, can communicate with each other for better, faster functioning. 'That's a pretty profound benefit to cyclists.
4. This kind of growth is especially important with each passing birthday, because as we age, our brains shrink and those connections weaken. Exercise restores and protects the brain cells. Neuroscientists say, "Adults who exercise display sharper memory skills, higher concentration levels, more fluid thinking, and greater problem-solving ability than those who are sedentary."
5. Cycling also elevates your mood, relieves anxiety, increases stress resistance, and even banishes the blues. "Exercise works in the same way as psychotherapy and antidepressants in the treatment of depression, maybe better," says Dr. Manjari. A recent study analyzing 26 years of research finds that even some exercise – as little as 20 to 30 minutes a day – can prevent depression over the long term.
6. Remember: although it's healthy, exercise itself is a stress, especially when you're just getting started or getting back into riding. When you first begin to exert yourself, your body releases a particular hormone to raise your heart rate, blood pressure, and blood glucose levels, says Meher Ahluwalia, PhD, a professor of integrative physiology. As you get fitter, it takes a longer, harder ride to trigger that same response.

Read the passage given below and answer the questions that follow:
The most alarming of man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with lethal materials. This pollution is for the most part irrevocable; the chain of evil it initiates is for the most part irreversible. In this contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world; radiation released through nuclear explosions into the air, comes to the earth in rain, lodges into the soil, enters the grass or corn, or wheat grown there and reaches the bones of a human being, there to remain until his death. Similarly, chemicals sprayed on crops lie long in soil, entering living organisms, passing from one to another in a chain of poisoning and death. Or they pass by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and harm those who drink from once pure wells.
It took hundreds of millions of years to produce the life that now inhabits the earth and reached a stage of adjustment and balance with its surroundings. The environment contained elements that were hostile as well as supporting. Even within the light of the sun, there were short wave radiations with power to injure. Given time, life has adjusted and a balance reached. For time is the essential ingredient, but in the modern world is no time.
The rapidity of change and the speed with which new situations are created follow the heedless pace of man rather than the deliberate pace of nature. Radiation is no longer the bombardment of cosmic rays; it is now the unnatural creation of man’s tampering with the atom. The chemicals to which life is asked to make adjustments are no longer merely calcium and silica and copper and all the rest of the minerals washed out of the rocks and carried in the rivers to the sea; they are the synthetic creations of man’s inventive mind, brewed in his laboratories, and having no counterparts in nature.

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)
- when the aircraft is overloaded
- at the time of landing or taking off
- when the crew become negligent
- when the passengers become panicky
- Complete the sentence appropriately with one word. (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
