(c) one moon mission had opened up many avenues in science and technology for mankind.
It was late evening of July 20. 1969, when we turned up the hostel radio. I was an engineering student at BITS, Pilani. I still remember the feverish excitement that gripped us from July 16 when Apollo 11. the US space rocket, took off from Cape Kennedy, Florida. Neil Armstrong and his team of astronauts, Edwin "Buzz" Aldrin and Michael Collins, were to land on moon, for the first time in human history. We listened 'with rapt attention when Armstrong declared: "That's one small step for a man, one giant leap for mankind."
His death on Saturday, August 25, is a moment to salute the romance of space science that Apollo 11 unleashed. It has changed forever the way we look at our planet Earth and its satellite, the moon.
Standing on powdery moondust, Armstrong put up his thumb, shut one eye and found his thumb blotting out the Earth. "It suddenly struck me that that tiny pea, pretty and blue, was the Earth” he said later. "I felt very, very small." But behind that humbling realisation stood a giant truth:
The effort to explore the universe united mankind in technology and knowledge. Each moon mission, about 110 till date, provided more confidence to take on bolder projects.

The hopping kangaroo is a familiar sight in every snapshot relating to Australia. Members of the kangaroo family can be as small as a rat or as big as a man. Kangaroos are found mainly in Australia, Tasmania and New Guinea. Kangaroos, which are big-footed marsupials that evolved in Australia, use their short front legs like arms. The man-sized kangaroos of Australia are capable of speeding up to 88 km/hr for short distances, their means of locomotion being their powerful hind legs, which carry them over the ground in jumps of 9 m or more at a time.
Weighing around 70 kg, they have an average lifespan of around six to eight years and a maximum lifetime of 20 years. When bothered by predators, kangaroos often head for the water, standing submerged to the chest and attempting to drown the attacker by holding him under water. Another defensive technique is to get their back to a tree and kick at their adversary with their clawed hind feet, sometimes with sufficient force to kill a man. Normally shy animals, they alert other kangaroos to danger by beating on the ground with their hind feet. This loud alarm signal carries over a long distance.
The tail is important for kangaroos. It holds them in balance and supports them when they sit or fight against other kangaroos. The kangaroo uses its short legs as arms. With them it scratches itself, cleans its fur and holds branches when it eats leaves. Kangaroos are marsupials and the females carry newborns in a pouch in front of their abdomens. The babies are born small and climb up into safety of the pouch. There, for the next 225 days or so, they eat, sleep and grow. Once they reach full development, they leave the pouch. A young kangaroo that leaves the pouch is called a ‘joey’. To keep from getting too hot, the kangaroos take naps in the afternoon and do most of their grazing at night. But the best stay-cool secret of these creatures is the spit bath! Kangaroos drool and lick saliva all over their faces and bodies to cool down.
On the basis of your reading of the above passage, complete the following sentences with appropriate words/phrases:
(a) When followed by predators, kangaroos submerge ____________ and _________________.
(b) The powerful hind legs help kangaroos to __________________.
(c) Kangaroos are mainly found in Australia and are ____________________.
(d) They use their front legs to ___________________.
(e) Kangaroos warn others of danger by _______________________.
(f) The secret of kangaroos to stay cool is ______________________.
(g) They use their tails to _________________________.

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.
a) What is the greatest advancement in modern technology?
b) What complicated works are computers capable of doing?
c) Write one use of computers.
d) Explain automation.
e) Why can't computers lead independent lives or rule the world?
f) How would computers as translating machines help people?
g) What was the prediction of Sir Leon about computers in the future?
h) How can computers help people going on holiday?
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
(a) What do doctors advise us about the habit of drinking coffee?
(b) What are the two versions of coffee that are drunk in America?
(c) State any two benefits of antioxidants.
(d) What does Vinson say about the consumption of antioxidants?
(e) Name any two popular sources of antioxidants.
(f) How does coffee outrank dates in the level of antioxidants?
(g) Mention any two benefits of coffee.
(h) What do researchers warn us about the excessive use of coffee?
Read the passage given below:
People tend to amass possessions, sometimes without being aware of doing so. They can have a delightful surprise when they find something useful which they did not know they owned. Those who never have to change house become indiscriminate collectors of what can only be described as clutter. They leave unwanted objects in drawers, cupboards, and attics for years in the belief that they may one day need them. Old people also accumulate belongings for two other reasons, lack of physical and mental energy, and sentiment. Things owned for a long time are full of associations with the past, perhaps with the relatives who are dead, and so they gradually acquire a sentimental value.
Some things are collected deliberately in an attempt to avoid wastage. Among these are string and brown paper, kept by thrifty people when a parcel has been opened. Collecting small items can be mania. A lady cuts out from newspaper sketches of model clothes that she would like to buy if she had money. As she is not rich, the chances are that she will never be able to afford such purchases. It is a harmless habit, but it litters up her desk.
Collecting as a serious hobby is quite different and has many advantages. It provides relaxation for leisure hours, as just looking at one’s treasure is always a joy. One doesn’t have to go out for amusement as the collection is housed at home. Whatever it consists of - stamps, records, first editions of books, china – there is always something to do in connection with it, from finding the right place for the latest addition to verifying facts in reference books. This hobby educates one not only in the chosen subject but also in general matters which have some bearing on it.
There are other benefits also. One gets to meet like-minded collectors to get advice, compare notes, exchange articles, to show off one’s latest find. So one’s circle of friends grows. Soon the hobby leads to traveling, perhaps a meeting in another town, possibly a trip abroad in search of a rare specimen, for collectors are not confined to one country. Over the years one may well become an authority on one’s hobby and will probably be asked to give informal talks to little gatherings and then, if successful, to larger audiences.

Read the passage given below :
It is surprising that sometimes we don't listen to what people say to us. We hear them, but we don't listen to them. I was curious to know how hearing is different from listening. I had thought both were synonyms, but gradually, I realised there is a big difference between the two words.
Hearing is a physical phenomenon. Whenever somebody speaks, the sound waves generated reach you, and you definitely hear whatever is said to you. However, even if you hear something, it doesn't always mean that you actually understand whatever is being said. Paying attention to whatever you hear means you are really listening. Consciously using your mind to understand whatever is being said is listening.
Diving deeper, I found that listening is not only hearing with attention, but is much more than that. Listening is hearing with full attention, and applying our mind. Most of the time, we listen to someone, but our minds are full of needles chatter and there doesn't seem to be enough space to accommodate what is being spoken.
We come with a lot of prejudices and preconceived notions about the speaker or the the subject on which he is talking. We pretend to listen to the speaker, but deep inside, we sit in judgement and are dying to pronounce right or wrong, true or false, yes or no. Sometimes, we even come prepared with a negative mindset of proving the speaker wrong. Even if the speaker says nothing harmful, we are ready pounce on him with our own version of things.
What we should ideally do is listen first with full awareness. Once, we have done that, we can decide whether we want to make a judgement or not. Once we do that, communication will be perfect and our interpersonal relationship will become so much better. Listening well doesn't mean one has to say the right thing at the right moment. In fact, sometimes if words are left unspoken, there is a feeling of tension and negativity. Therefore, it is better to speak out your mind, but do so with awareness after listening to the speaker with full concentration.
Let's look at this in another way. When you really listen, you imbibe not only what is being spoken, but you also understand what is not spoken as well. Most of the time we don't really listen even to people who really matter to us. That's how misunderstandings grow among families, husbands and wives, brothers and sisters.
(A) On the basis of your reading of the above passage make notes on it, using heading and sub-headings. Use recognizable abbreviations (wherever necessary − minimum four) and a format you consider suitable. Also supply an appropriate title to it.
(B) Write a summary of the passage in about 80 words.

Read the following extract and answer the question given below: (11)
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 l ·3 million billion would the earth be too hot to be habitable. And though it would feel like being in a 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 worldwideThough
population has grown, the rate of growth has fallen sharply. Twenty years ago, the UN projected that population would reach l l · 16 billion in 2050, today they say it will reach only 9·37 billion. Moreover, 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 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? (1)
( 2) How does the writer explain that the fertility is on the
decline? (2)
(3) What does the extract predict about the fear-, of scarcity of food? (2)
( 4) How will population become a gift in the global market
scene? (2)
(5) Rewrite the following sentences in the ways instructed:
(i) The earth could withstand upto 200,000 times the
current population.
(Rewrite the sentence using the modal auxiliary showing 'certainty'.) (I)
(ii) The earth would be too hot to be habitable.
(Remove ' too' and rewrite the sentence.) (1)
(iii) These resources are being used.
(Rewrite the sentence beginning with, 'We ............ ') (I)
( 6) Write the antonyms of:
(i) habitable (1/2)
.
(ii) stabilize ( 1/2 )

My mother was still managing Green's, even though its days were numbered. The day after my return I joined her in the small office, where she sat behind her over-large desk, telephone on her right and the latest paperback western before her, ready to be taken up when noting much was happening – which was fairly often. My mother enjoyed reading westerns-particularly Luke Short, Max Brand, and Clarence E Mulfordmuch in the same way that I enjoyed detective fiction. Both genres were freely available in cheap collins ‘White Circle’, edition published during and just after the War.
We discussed the affair of the skeleton in the cupboard, but as there was no longer any mystery about it, there was nothing for me to investigate. However, armed with the key to the store room, I went down to the basement on my own and made a thorough search of all the old furniture, on the offchance that another skeleton moght tumble out of a cupboard or be found jammed into a drawer or trunk. I did find some old tennis rackets, back numbers of Punch, a cracked china chamber-pot, some old postcards of Darjeeling and Simla, and a framed photograph of King Edward the Seventh. I took the copies of ‘Punch’ to my room and read the reviews of all the plays that had been running in London between 1926 and 1930, thus becoming an authority on the theatre in England of that period.

In 1945 in Bay Roberts, Canada, a 12- year old boy saw something in a shop window that set his heart racing. But the price - five dollars- was far beyond Reuben Earle's means. Five dollars would buy almost a week's groceries for his family.
Reuben couldn't ask his father for the money. everything Mark Earle made fishing. Reuben's mother. Dora, stretched like elastic to feed and clothe their five children.
Nevertheless, he opened the shop's weathered door and went inside. Standing proud and straight in his flour-sack shirt and washed out trousers, he told the shopkeeper what he wanted, adding, "but I don't have the money now. can you please hold it for me?"
"I will try," the shopkeeper smiled. "Folks around here don't usually have that kind of money to spend on things. It should keep for a while."
Reuben respectfully touched his worn cap and walked out into the May sunlight. The bay rippled in a freshening wind that ruffled his short hair. There was purpose in his loping stride. He would raise the five dollars and not tell anybody.
Hearing the sound of hammering from a side street. Reuben had an idea.
He ran towards the sound and stopped at a construction site. People built their own homes in Bay Roberts, using nails purchased in burlap sacks from a local factory. Sometimes the sacks were discarded is the flurry of building, and Reuben knew he could sell them back to the factory for five cents apiece.

Read the following extract and complete the table given below:
Children are perpetually asking questions. As adults, we are awkward with questions. We link the act of asking questions to ignorance. It indicates that we do not know; hence, we may look stupid while asking questions.
Children have no shame, whereas adults suffer from layers and layers of shame. Because children have no shame, they are more capable of failing at something and moving on from it. Our sense of shame makes us inhibited. So we do not try new things at work.
Children quickly make friends with strangers. Put two small kids alongside a few toys and they will start playing before they care to know about each other’s antecedents. As adults, we seek the false comfort of known relationships before we agree to play with each other.
Children freely express their emotions; adults learn to suppress their emotional side. We come to the workplace and are frequently counselled, “Do not get emotional.”
Children play. They find play in everything. Adults shun play and consider it the opposite of “serious work”. To a child, every act is an act of play.

Read the following passage carefully.
1. Few guessed that this quiet, parentless girl growing up in New York City would one day become the First Lady of the United States. Even fewer thought she would become an author and lecturer and a woman much admired and loved by people throughout the world.
2. Born Anna Eleanor Roosevelt in 1884 to wealthy, but troubled parents who both died while she was young, Roosevelt was cared for by her grandmother and sent to school in England. In 1905, she married her distant cousin, Franklin Delano Roosevelt. She and her husband had six children. Although they were wealthy, her life was not easy and she suffered several personal tragedies. Her second son died when he was a baby. In 1921, her strong athletic husband was stricken with polio, which left him physically disabled for life.
3. Eleanor Roosevelt was a remarkable woman who had great intelligence and tremendous strength of character. She never let things get her down. She nursed her husband back to good health and encouraged him to remain in politics. She then helped him to become Governor of New York, and in 1933, President of the United States.
4. While her husband was President, she took a great interest in all the affairs of the country. She became her husband's legs and eyes; she visited prisons and hospitals; she went down into mines, up scaffoldings, and into factories. Roosevelt was tireless and daring. During the depression, she travelled all over the country bringing goodwill, reassurance, and help to people without food and jobs. During World War II she visited American soldiers in camps all over the world. The United States had never known a First Lady like her.
5. Roosevelt also kept in touch with the American people through a daily newspaper column called 'My Day'. She broadcast on the radio and delivered lectures, all first for a First Lady.
1.1 On the basis of your understanding of the above passage answer the following questions: (any eight)
(a) How was Eleanor Roosevelt's personality in contrast to what she became?
(b) Apart from being the First Lady what else did she have to her credit?
(c) What challenges did she face in her personal life but remained unfazed?
(d) Eleanor was a strong woman who helped her husband become the President of America. How?
(e) What does the statement: 'she became her husband's legs and eyes' mean?
(f) What was her special contribution during the depression?
(g) How did she motivate soldiers during World War II?

(i) What side of her personality is reflected in this passage?
Read the passage given below carefully and answer the questions that follow.
1. Overpowering prey is a challenge for creatures that do not have limbs. Some species like Russell's viper inject poison. Some others opt for an alternative non-chemical method – rat snakes, for instance, catch and push their prey against the ground, while pythons use their muscle power to crush their prey to death. But snakes can't be neatly divided into poisonous and non-poisonous categories.
2. Even species listed as non-poisonous aren't completely free of poison. The common Sand Boa, for instance, produces secretions particularly poisonous to birds. So the species doesn't take any chance – it crushes its prey) and injects poison as an extra step.
3. Do vipers need poison powerful enough to kill hundreds of rats with just one drop? After all, they eat only one or two at a time.
4. While hunting animals try their worst to kill most efficiently, their prey uses any trick to avoid becoming a meal, such as developing immunity to poison.) For instance, Californian ground squirrels are resistant to Northern Pacific rattlesnake poison.
5. Competition with prey is not the only thing driving snakes to evolve more and more deadly poison. Snakes also struggle to avoid becoming prey themselves.
6. Some snake killers have partial immunity to poison. Famously, mongooses are highly resistant to cobra poison, and with their speed and agility, kill snakes fearlessly. It would be the death of cobras as a species if they didn't evolve a more deadly poison to stop mongooses.
7. Poison has another important role. It's an extreme meat softener, specific enzymes break up the insides of the prey. Normally, a reptile depends on the sun's warm rays to aid digestion.
8. But I wonder if we cannot use venom in our favour. In remote parts of India, local hospitality often involves leather tough meat. I chew and chew until my jaws ache. If I spit it out or refuse, our hosts would be offended, I swallow like a python stuffing a deer down its throat and hope I don't choke. If only I had poison.
(b) How does Sand Boa kill its prey?
(c) There is a constant tussle between the hunting animal and its prey? Why?
(e) What difficulty does the writer face when he is entertained in the remote parts of India?

d. prey
b. hardens
c. softens
d. breaks down
iii. Californian squirrels are ______________ rattlesnake poison.

a. Liquid substances released from glands (para 2)
c. Particular (para 7)
Read the passage given below.
| 5 | Changing food preferences have brought about rapid changes in the structure of the Indian diet. The rapid proliferation of multinational fast food companies and the influence of Western culture have replaced traditional home-cooked meals with ready-to-eat, processed foods thus increasing the risk of chronic diseases in urban Indians. Therefore, nurturing healthy eating habits among Indians from an early age would help to reduce health risks. |
| 10 | To date, little is known about the quality and quantity of foods and beverages consumed by urban Indian adolescents. This lack of evidence is a significant barrier to the development of effective nutrition promotion and disease prevention measures. |

Therefore, a self-administered, semi-quantitative, 59-item meal-based food frequency questionnaire (FFQ) was developed to assess the dietary intake of adolescents. A total of 1026 students (aged 14-16 years) attending private, English-speaking schools in Kolkata completed the survey. A sample percentage of the food consumption pattern is displayed.
The survey results report poor food consumption patterns and highlight the need to design healthy eating initiatives. Interestingly, while there were no gender differences in the consumption of legumes and fried snacks, the survey found more females consumed cereals, vegetables and fruits than their male counterparts. |
| 25 | In conclusion, the report suggested that schools ought to incorporate food literacy concepts into their curriculum as they have the potential of increasing the fruit and vegetable intake of teenagers. Additionally, healthy school canteen policies with improved availability, accessibility, variety and affordability of healthy food choices would support the consumption of nutritious food in students. |
Based on your understanding of the passage, answer the questions given below.
- What does the researcher mean by ‘changing food preferences'?
- Why was this survey on the food consumption of adolescents undertaken?
- With reference to the above figure, write one conclusion about students' consumption of energy-dense drinks.
- What can be concluded from the ‘no intake’ data of fruit consumption versus energy-dense snacks, with reference to the above figure?
- There were gender differences observed in the consumption of healthy foods, according to the survey. Substantiate.
- Why is ‘affordability’ recommended as a significant feature of a school canteen policy?
- Identify a word from lines 9-18 indicating that the questionnaire was specifically designed to be completed by a respondent without the intervention of the researcher collecting the data.
Read the following passage and do the activities.
A1. Choose the correct option. (2)
- Thousands of birds were killed due to oil spills because ______.
- It suffocated them
- It was poisonous
- Birds couldn't enter the sea
- There was no fish to feed on
- The primary components of crude oil are ______.
- Methane and ethane
- Carbon and hydrogen
- Sulphur compounds
- Naphthalene
| During the Gulf War, a few years back, tens of thousands of sea birds were killed due to oil spills. Do you know what makes crude oil on ocean water so deadly? Crude oil is not used in the state it is produced at the off-shore wells. It is converted in refineries into a wide range of products such as gasoline, kerosene, diesel, fuel oils, and petrochemical feed-stocks. Before it is refined, the oil also contains potentially fatal components. Crude oil is made up of compounds of carbon and hydrogen called hydrocarbons. These hydrocarbons may be paraffin, the oil that is used as fuel in heaters and lamps or cycloparaffins (naphthenes) or aromatic compounds in varying proportions. While crudes found in the US are mostly paraffinic, these found along the Gulf Coast are naphthenic which contain sulphur compounds in varying amounts, a small amount of nitrogen and very little oxygen. Every variety of crude oil has nickel and vanadium in high concentration. Iron may be found in organic form due to the corrosion of pipes. Paraffins like methane and ethane are asphyxiants, substances that cause suffocation. The effects of cycloparaffins are more or less similar to those of paraffins but unsaturated paraffins are more noxious, than saturated ones. The sulphur present in crude oil may be toxic. The mechanism of toxic action seems to involve its breakdown to hydrogen sulphide. They will act principally on the .nervous system with death resulting mainly from respiratory paralysis. Sulphur in the form of aromatic thiophenes, benzothiophenes can damage the livers and kidneys of sea animals. Sulphur compounds like mercaptens can be very dangerous too. |

Most cities, may not be prohibit hawking as a profession, but do place restrictions on the use of urban space. Therefore, a comprehensive study was conducted in 1998-99 on street vending, to provide concrete data for furthering the cause of the hawkers. Eight cities were selected - Mumbai, Ahmedabad, Kolkata, Imphal, Patna, Bhubaneswar and Bangalore. Three points were important while selecting respondents –hawkers were from different parts of a city; sold a variety of goods and adequate numbers of women were covered. The questionnaire was included questions on personal details, details regarding the work and the hazards faced. Table: Results of the survey

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)

- decreased
- increased
- remained constant
- been alarming
