Question: Read the following article and select the best answer. Article: Cancer is feared by everyone. And there is more and more fear about cancer. Not the disease itself -- there is no such thing as a high incidence rates of cancer. Except for lung cancer, mostly caused by cigarette smoking, the incidence rates are not on the rise. However, some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety. The earth itself is coming to seem like a huge carcinogen . The ordinary, more or less, scientific statement that something between 80 and 90 percent of all cancers are due to things in the environment is taken to mean that none of us will be safe until the whole environment is "cleaned up." This is not at all the meaning. The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world -- for example, the high incidence of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data show there may be specific environmental influences, but largely based on personal life-style, which determines the incidence of various forms of cancer in different communities -- that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere. Question: According to the passage, the incidence of cancer is generally believed _ . - to be based on inactive life style - to be due to anxiety - to result from environmental influences - to be caused by heavy smoking
Answer: to result from environmental influences

Question: Read the following article and select the best answer. Article: School uniforms are becoming more and more popular across the U.S.A. That's no surprise,because they offer many benefits. They immediately end the powerful social sorting and labeling that come from clothing. If all students are dressed in the same way,they will not pay too much attention to their clothing,and some of them will not be laughed at for wearing the "wrong" clothes. Some people are against the strict rule of school uniforms,but they do not realize that students already accept a kind of rule -- wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers ; school uniforms tear those barriers down. As in other places,uniforms remind the wearers of their purposes and duties. For example,when a man or woman puts on a police uniform,he or she becomes,for a time,the symbol of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students,the school uniform reminds them that their task for the six or seven hours they are in school is to get an education. Some parents are unhappy about uniforms,saying that school uniforms will affect their children's "creativity". First,as noted above,the clothes students choose to wear do not necessarily express their individuality . They just copy their classmates. Second,students have the rest of the day to be as creative as they like. While they're in school,their job is to master reading,writing,and maths; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way. Question: From the passage we learn that uniforms in general_. - prevent the wearers from being laughed at - help the wearers keep their duties in mind - are seen as a symbol of power - help to create social barriers
Answer: help the wearers keep their duties in mind
