17.

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

D/c

(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

此题思路?为什么不选D

再次指出，食物的贵贱跟profit没直接关系

退一步讲， less expensive 我可以吃大量的，不直接导致profit降低

关于原因二:a restaurant's customers who spend less time at their meals typically order less expensive meals 花费的时间少会使得点更少贵的食物  但是没有说总的收入减少了 存在这样的可能性是虽然点贵的少了 但是点便宜的多了很多并且它们增加的profit能够cover 减少的点贵的菜的profit 所以点更少贵的并不能保证profit降低了

为什么不能这样想：

原因2：吃完就走必定在饭馆花的时间就少，而刚好D说a restaurant's customers who spend less time at their meals typically order less expensive meals （花费的时间少会使得点更少贵的食物），那么这样不正使profit降低了吗？

结论：换高凳增加收入 原因1：能看明星 原因2：吃完就走

反驳：C exception to the generalization about lingering 就是吃完不走

D profits 跟价格无关，只跟差价有关
