GMATPrep里面的一道逻辑题，欢迎讨论

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 the 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.

参考答案是C，我选了D。感觉C是无关项，原文说“人们都喜欢坐在stools上，而且坐在stools上的人在餐馆呆的时间不比坐在standard height上的人长，从而如果餐馆如果把tables都换成stools的话，利润会增大。”我认为利润增大的前提是“在其他条件不变时，来的人数会不变或变大，或者每人的花费都一样”，所以如果像D所说的，如果坐stools的人在餐馆呆的时间短，但其花费也同样少的话，那么利润显然就不一定会增大。

不知道这样的理解是否正确？

D说的和原文说的改凳子没关系. 是无关选项.

原文没说坐S的人呆的短,只说不比Standard的长.不能说就是短.可能一样.
