问题 The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotas will help "mini-mills" flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas. Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?

选项 A、Quality rather than price is a major factor in determining the type of steel to be used for a particular application.
B、Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills.
C、American quotas on imported goods have often induced other countries to impose similar quotas on American goods.
D、Domestic "mini-mills" consistently produce better grades of steel than do the big American mills.
E、Domestic "mini-mills" produce low-volume, specialized types of steels that are not produced by the big American steel mills.

答案 E

解析 如果,像选项(E)指出的一样,大型和小型厂生产不同类型的钢材,小型厂销量的增加不一定导致大型厂销量的减少,因此,选项(E)对于该宣称提出了最严重的质疑,是正确答案。选项(A)没有提供足够的关于外国和国内钢厂生产的钢铁的相对质量的信息来质疑该宣称,相似地,选项(B)没有提供关于美国小型厂的足够信息。选项(C)没有提供关于外国施加配额的可能后果的足够信息来质疑该宣称。选项(D)倾向于支持该宣称,因为更好的钢应该比差质量的钢销量大。
