(Question)
Read the following article and select the best answer. Article: A person who is deaf when he is born is usually dumb as well. There may be nothing wrong with his mouth and tongue, but he cannot speak. This is because he cannot hear people, so he has nothing to imitate . He may try to make sounds himself, but cannot hear his own voice. However, even though he finds it difficult to speak and cannot hear, he can learn to read. Nowadays such persons can also be taught to speak because we have modern methods and equipment, but we did not have these when Helen Keller was born. Even with modern methods and equipment, however, it is not easy for deaf children to learn to speak, though most of them succeed. When a child is deaf and blind as well, it becomes much more difficult, though it is possible. Helen Keller was born in 1880. She became very ill at the age of nineteen months. Medical knowledge was not as great then as it is now. She did not die but lost her sight and hearing. As a result, she became dumb as well. Her parents did their best to teach her, but she couldn't speak by the age of six. Then, in 1887, a teacher, Miss Sullivan, came to live with her. Miss Sullivan herself had been blind. She had been partly cured. Though she could not see very well, she was not blind. Helen was a difficult pupil at first, but in a month Helen had learned how to understand signs and how to make them herself. At last in spite of her great difficulties, Helen learned to read, write and speak, even though she was deaf and blind. She even went to college and had full education. She wrote many books, and though other people have written books about her, her own books are the ones that best explain how it feels to be deaf, dumb and blind. Her best book is The Story of My Life. Perhaps you have read it. Though it was written in 1902, it is still a very interesting book. Even if you have not read it, you may have heard of Helen Keller. Question: When Helen was nineteen months old, _ . - she died of illness - she was healthy - she was very ill - she began to learn to speak
(Answer)
she was very ill

Question: Read the following article and select the best answer. Article: Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only pretty, but NASA scientists are finding them to be surprisingly useful in absorbing possible harmful gases and cleaning the air inside modern buildings. NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against "Sick Building Syndrome ". Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wloverton, a senior research scientist at NASA. Based on preliminary evaluations of the use of common indoor plants for indoor air purification ,NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution. NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment. "We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places," he concludes. "Combining nature with technology can increase the effectiveness of plants in removing air pollutants," he said. NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings. You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work--where people feel better, perform better, and enjoy life more. Question: The main idea of the passage is _ . - plants are very useful to human beings - indoor plants can help remove indoor air pollution - indoor plants should be raised in both homes and offices - NASA have studied indoor plants for many years

indoor plants can help remove indoor air pollution
