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
我选了D，虽然顾客待的时间短，但他们点餐一般价格要低，说明饭店的利润也可能下降啊，不是正好驳斥了文章吗？为什么D不对呢？

如果原本换了10批客人，每台点的很贵100元，而现在换了30批客人，每台点了30元，那么利润也可能下降，意思是利润可能增加也可能减少咯？
所以C正确是因为他驳斥了such seating would afford a better view of the celebrities这点吗？

但是D没有考虑到换台率啊~~如果原本换了10批客人，每台点的很贵100元，而现在换了30批客人，每台点了50元。符合题意吧，但这样算来，利润是上升的~~
