Question: Article: When school was out, I hurried to find my sister and get out of the schoolyard before seeing anybody in my class. But Barbara and her friends had beaten us to the playground entrance and they seemed to be waiting for us. Barbara said, "So now you' re in the A class. " She sounded impressed. "What' s the A class? "I asked. Everybody made superior yet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, Dopey? Didn' t you know you were in the C class before, way in the back of the room? " Of course I hadn' t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, and the idea of subdivisions within a grade had never occurred to me. The subdividing for the first marking period had been done before I came to the school, and I had never, in the six weeks I' d been there, talked to anyone long enough to find out about the A, B, and C classes. I still could not understand why that had made such a difference to Barbara and her friends. I didn' t yet know that it was shameful and dirty to be a transient laborer and ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house. I didn' t know that we were gypsies, really (how that thought would have excited me then! ), and that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn' t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here and there like mists or winds, I didn' t know that I was the only child who had camped on the Baumann' s land ever to get out of the C class. I didn' t know that school administrators and civic leaders held conferences to talk about the problem of transient laborers. I only knew that for two happy days I walked to school with Barbara and her friends, played hopscotch and jumped rope with them at class intervals, and was even invited into the house for some ginger ale--a strange drink I had never tasted before.

Question: Article: Britons spend as much as nearly five hours a week keeping their homes clean, a survey found. Kitchens are cleaned most often, while doing the oven and windows are the least popular jobs. In total, they spend just over PS1 billion a year on products to keep the dirt at bay -- almost PS40 per household. Market analyst Mintel found a clear division of labour. While the average Briton spends 4 hours, 40 minutes cleaning their home each week, men spend just 3 hours, 53 minutes compared to 5 hours, 25 minutes for women. And while seven in ten women say they do most of the cleaning, this falls to four in ten for men. Confirming many parents' feelings, only one in five adult children and over living at their parents' home helps with cleaning chores, with children under 18 doing even less. Last year, the household cleaning market was worth PS1.06 billion, which equates to annual spending of PS39.89 per household. Those looking for the cleanest homes in the country should head to Scotland, where people spend an average of five fours, 6 minutes, which is closely followed by East and West Midlands at five hours, 1 minute. In comparison, the least number of hours spent in cleaning is spent in the southeast/East Anglia at four hours, 18 minutes. The southwest and Wales stand at four hours, 46 minutes, the northwest four hours, 44 minutes, and Yorkshire and the Humber four hours, 21 minutes. According to Richard Caines, Mintel's senior household care analyst, men still lag women in the household cleaning stakes and spend on average an hour and a half less time cleaning their home, suggesting an opportunity for a campaign to encourage more cleaning by men to helpredressthis imbalance. The number of households that need cleaning is continuing to grow, but pressure on time from increasingly busy lives limits the number of hours people are willing or able to spend cleaning their homes. This means the market will see an increasing focus on easy-to-use, but effective hard surface cleaners and cleaning equipment. Such products can help encourage more cleaning to be done in less time, but as well as focusing on more convenient products, cleaning brands can also inject an element of fun into campaigns through encouraging a more shared approach that involves the whole family. This will also help to address the gender imbalance and get older children to make more of a contribution to cleaning.

Question: Article: Not long ago, many doctors in the West laughed at the suggestion that they might learn something from traditional Asian systems of healing. Most of them thought that Asian herbal medicine and acupuncture were believed in only by simple people who knew no better. Western doctors relied mainly on chemical cures as the safest and surest way to treat illnesses. The scientific age of antibiotics , "miracle drugs" and heart transplants encouraged the public to believe that there must be a pill for every illness. It was true that often the drug companies provided what the public wanted: a speedy temporary cure and did not remove the real cause of the illness. Moreover, some people actually became ill through taking too much medicine. Many people in the West are now beginning to look for more natural cures for their illnesses and often they turn to the ancient wisdom of the East. There are some doctors in Britain now who offer their patients acupuncture treatment. Recently an Indian company which produces a natural medicine based on the biba root has sold some to Germany. The World Health Organization(WHO) encourages doctors not to rely too greatly on expensive Western medicines but to choose them carefully and also use their traditional herbal cures. The mixture of Eastern and Western medicine has been practiced very successfully in China. China is still the only country in the world where the traditional doctor using herbal medicine and acupuncture is as respected as the Western-trained doctor. Through China all types of doctors are expected to work together. Western-style doctors are required to take at least a one-year course in traditional medicine, and the acupunctures must also study the basics of western medicine. China's way of "having the best of both worlds" has greatly impressed many visiting doctors from the West. Experts from the WHO have decided that the time has come to study herbal medicine very carefully and to decide, by carefully controlled scientific experiments, what good these medicine might do. They are especially interested in finding cures for illnesses which Western medicine has found "incurable". Six WHO units have been set up in Hong Kong, Seoul, Sri Lanka, London and Chicago, and so far the results have been encouraging.
Question: What is the true reason for Western doctors to turn to the ancient wisdom of the East ?
