Read the following passage about human life expectancy and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Milu was born in a small village in the north of India, and never had the chance of going to school, because her family needed her to work. So she grew up never having learned to read or write. She was a little sad about it, but she didn't let it upset her too much, and tried to think about other things.

She went through life, never being able to do what she wanted, because she felt that if she couldn't read, then she was somehow less than everybody else. This meant that she didn't make many friends and didn't go out much. She thought people would think she was stupid, and she didn't want them to laugh at her.

When she was fifty-six, she got a job cleaning a school and when she had finished her work, she used to sit and watch the little kids do their lessons. She didn't realise that one of the teachers watched her while she watched the kids, and one day, as she was about to leave, the teacher asked her to sit in the class. The kids thought it was very funny, but the teacher patiently started Milu on her first lesson to learn to read.

That was a few years ago, and now Milu can read and write as well as any of the other kids. She still cleans the school because she likes her job, but she doesn't feel less than everybody else anymore. The teacher, who is now her friend, sometimes gives her a book to read and she learns about people living in other parts of the world.

She has a granddaughter who studies at the same school, and sometimes she helps her with her homework. Being able to do that makes her feel so happy that when she stays alone she has a little cry. When she was in her little village as a child, she would never have dreamt that one day she would be able to help her granddaughter with her homework. She owes gratitude to her teacher friend for the gift she was given.

Which of the following is NOT what Milu gains from learning?

Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly irritating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a by-product of our advancing technology causes physical and psychological harm, and detracts from the quality of life for those who are exposed to it.

Unlike the eyes, which can be covered by the eyelids against strong light, the ear has no lid, and is, therefore, always open and vulnerable; noise penetrates without protection. Noise causes effects that the hearer cannot control and to which the body never becomes  accustomeLoud noises instinctively signal danger to any organism with a hearing mechanism, including human beings. In response, heartbeat and respiration accelerate, blood vessels constrict, the skin pales, and muscles tense. In fact, there is a general increase in functioning brought about by the flow of adrenaline released in response to fear, and some of these responses persist even longer than the noise, occasionally as long as thirty minutes after the sound has ceased.

Because noise is unavoidable in a complex, industrial society, we are constantly responding in the same way that we would respond to danger. Recently, researchers have concluded that noise and our response may be much more than an annoyance. It may be a serious threat to physical and psychological health and well-being, causing damage not only to the ear and brain but also to the heart and stomach. We have long known that hearing loss is America's number one nonfatal health problem, but now we are learning that some of us with heart disease and ulcers may be victims of noise as well. Fetuses exposed to noise tend to be overactive, they cry easily, and they are more sensitive to gastrointestinal problems after birth. In addition, the psychic effect of noise is very important. Nervousness, irritability, tension, and anxiety increase affecting the quality of rest during sleep, and the efficiency of activities during waking hours, as well as the way that we interact with each other.
