Only three strategies are available for controlling cancer: prevention, screening and treatment. Lung cancer causes more deaths than any other types of cancer. A major cause of the disease is not (21) known; there is no good evidence that screening is much helpful, and treatment (22) in about 90 percent of all cases. At present, therefore, the main strategy must be (23) . This may not always be true, of course, as for some other types of cancer, research (24) the past few decades has produced (or suggested) some importance in prevention, screening or treatment.(25) , however, we consider not what research may one day offer but what today’s knowledge could already deliver that is not being delivered, then the most practicable and cost-effective opportunities for (26) . premature death from cancer, especially lung cancer, probably involve neither screening nor improved (27) , but prevention.This conclusion does not depend on the unrealistic assumption that we can (28) tobacco.

Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work. Since 1980 the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsides by foreign governments. Another 340 charge that foreign companies "dumped" their products in the United States at "less than fair value". Even when no unfair practices are all alleged, the simple claim that an industry has been injured by imports is sufficient ground to seek relief.Contrary to the general impression, this quest for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop an intricate Web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company.Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports-and that the United States company received a subsidy from a foreign government to build its plant abroad-the United States company’s products will be uncompetitive in the United States, since they would be subject to duties.Perhaps the most brazen case occurred when the ITC investigated allegations that Canadian companies were injuring the United States salt industry by dumping rock salt, used to deice roads. The bizarre aspect of the complaint was that a foreign conglomerate with United States operations was crying for help against a United States company with foreign operations. The "United States" company claiming injury was a subsidiary of a Dutch conglomerate, while the "Canadian" companies included a subsidary of a Chicago firm that was the second largest domestic producer of rock salt. It can be inferred from the passage that the minimal basis for a complaint to the International Trade Commission is().
M: How did you do on the examW: I passed, but I didn’t do so well. The essay question was the worst part for me. How about youM: I did all right on everything except the essay question, too. I wasn’t really prepared to write about the tribes in the rainforests of Brazil. We studied the rainforests for only a few days. I didn’t think it would be on the test.W: Me either. I thought for sure that he would ask us something about the Incas in Peru or maybe the mountain peoples in Chile. I studied most of the material on these groups and didn’t spend much time on the people of the rainforest. Do you know how much theexam counts towards our final gradeM: I think it’s 30 percent.W: Thirty percent! Oh no, I’m in deep trouble this time! That means I’ll have to get A’s on everything else to get a decent grade.M: That may not be too hard. We’ve already gone through most of the readings that the class is supposed to cover. After next week it will just be review. But then there is the final paper, of course.W: Yes. I was hoping to do well on this test so I could relax when writing my paper, but now it looks like I’ll have to spend more time preparing to write that paper.M: Well, I will too. Hey, I’m kind of hungry. I think I’ll go to get some lunch. Do you feel like joining meW: I’d love to, but I have to go home and study. I’ll call you later. Where is the man going after they finish talking()
