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
some celebrities come to the Hollywood to be seen, and so might choose to sit at the tall tables if they were available
the price of meals ordered by celebrities dining at the Hollywood compensates for the longer time, if any, they spend lingering over their meals
a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering
a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer
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
错选了D，我觉得对d最好的解释就是：D选项的逻辑是：高椅子呆的时间少—待的时间少的人一般点的也越便宜—换成高椅子会使单点得更便宜，所以换高椅子虽然接的客多了，但点的也会便宜。但是，这种逻辑关系很可能是反的。也许是因为这些本来打算不待多久的人才会去高椅子，如果你店里的所有椅子都换成高椅子，难道大家都会因此点得更少更便宜吗？正确的理解应该是只有用餐时间少的人才会去坐高椅子，而不是高椅子会使人用餐时间少单少。
