I'm taking a test and have to guess the right answer to the question after the article. Article: The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government's health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor. Daily habits like eating more healthy food would have kept millions of families from becoming _ if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and frits, seems to be quite important. One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better and reduce stress. In addition, health education plays a key role in improving people's health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one's family medical history is an effective way to help keep healthy. Information about health problem among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, Which will work before it is too late. However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education. Question: We learn form the passage that _ Options: A: dressing warmly can prevent disease B: a balanced diet is cheaper than regular exercise C: the more health education, the better D: the government's health budget should be increased

I'm taking a test and have to guess the right answer to the question after the article. Article: Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated ," Edwards points out. "The problem is how we promote (......) that, especially for those without friends or help. A robotic dog could be a solution." In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own." The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns. "At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry, " Beck says. "But it's amazing how quickly we have given up that belief." "Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds. " Question: In the research, the old people are asked to _ . Options: A: note the activities of AIBOs B: keep AIBOs at home for 12 weeks C: record their feelings and activity. D: analyze the collected information

Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: Wearing ties was originally the mark of Britain's most powerful classes, which made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger tribe--the business tribe. You cannot wear a tie if you work with machinery. So wearing a tie became a sign that you were a man who used your brain to make a living, rather than your hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who didn't wear a piece of color1ed silk around his neck. This is how millions of people came to be wearing ties across the world. They are part of the uniform of business. "Ties offer a point of indifference," says John Milne, head of the British Guide of Tie Makers. "They give a chance to say something about their own personality." So if you happen to meet a man with a very brightly color1ed tie, there is a good chance that he is the office joker. There is also a good chance that he will be wearing brightly color1ed socks. Is there a future for ties? The signs are not promising. Tie wearing seems to be rare among the new bread of entrepreneurs in the Internet and new technology industries. Many political leaders,including British Prime Minister Tony Blair, now go without ties. This shows they are men of the people--but not the people wearing ties. Up until around 1960, it was common for men across the Western world to wear hats as part of their business uniform. That changed with the election of John F. Kennedy to the presidency of the United States. Kennedy never wore a hat in fact his nickname was"hatless Jack". Seeing that the most powerful man in the world did not have to wear a hat, millions of other men decided that they did not have to, either. Hats simply vanished across the Western world. Perhaps"tieless Tony"(UK Prime Minister Tony Blair) will have the same effect as "hatless Jack". Question: In the business world,wearing a tie was necessary because _ . Options: A: it showed you were a brainworker B: it showed you got a good salary C: it showed you were an employer D: it showed you were welltrained

A
