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 tablesdaan

答案C 没看明白，能否帮我解释一下？

我之前也一直在晕这道题，来了CD后看贴发现更晕了，居然还有说这是支持题的。下面是一些我的理解：

前提：餐馆现在都是标准桌，但是很多人都希望能有高的桌子还有凳子，这样可以更方便看明星。并且，那些坐在凳子上吃饭的人要比坐在标准桌吃饭的人呆的时间少，（这样可以提高餐馆流通率），所以应设置一些高桌子和凳子，这样会有更好的效益。

问题：削弱以上前提。

C项：那些选择高桌子的人，并不是普遍认为的会像坐在凳子上吃饭的人一样停留较短。所以餐馆提高流通率的目的未达到，利润也不会上升。

a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering

我理解的是选择高椅子的客人一般迟迟不离去的只是个例外， 所以消弱了
