请教：prep里的一道题

17.   (26864-!-item-!-188;#058&003368)

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

这道题为什么选C啊？

文章说，要换高stools，因为diners 不会坐太久，所以换的结果会盈利。

C 将要选择sit at a tall table的人是个例外，不会到处走动，说明坐的久，那么结论就不成立了～～

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

明星们点餐的价格 在一个更长的时间内 弥补了他们花费在用餐之间闲逛（翻译不好尽量理解哈）

盈利的增加是因为dinner到处逛，和celebrity有什么关系？

B无关选项

我觉得此题目是flaw题型，The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that， 是要指出argument中有问题的部分，所以使得该结论易受到攻击。题干中说 Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables

意思是做高椅子的在饭馆停留的时间短，这样的话就可以很快腾出位置招待其他客人，这样的话就增加了客流量增加了收入。在指出该论断的flaw时，C) a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering 说明做椅子并且很快消费完毕的人是例外，大部分人都会停留很长时间，所以达不到预期的目的来增加利润。

本人开始也选错了选择了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，后来仔细想想是否应该这样理解，期待大家讨论
