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?
(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 steel that are not produced by the big American steel mills.
疑问：选项又没有说 Domestic “mini-mills”only produce sth which not produced by big mills. 所以Domestic mini－mills take business from big mills的嫌疑还是潜在啊。

At present the Hollywood Restaurant has only standard-height tables. However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities. Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables. Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that
(A) some celebrities come to the Hollywood to be seen, and so might choose to sit at the tall tables if they were available (B) the price of meals ordered by celebrities dining at the Hollywood compensates for the longer time, if any, they spend lingering over their meals (C) a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering (D) a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer (E) with enough tall tables to accommodate all the Hollywood's customers interested in such seating, there would be no view except of other tall tables
