标题: ｐｒｅｐ逻辑请教 [打印本页] 作者: gmatziyu 时间: 2010-2-25 14:13 标题: ｐｒｅｐ逻辑请教 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 请问这题为什么选择ｃ呢？感觉ｅ好像也是对的。。。 谢谢 作者: shiningsmile 时间: 2012-3-28 21:00
同问啊，选E为什么不行呢？高桌子把视线都挡了，还怎么看明星呢？作者: yussy 时间: 2012-3-28 22:45
这道题不是weaken...而是argument中的flaw
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that 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
把E代到问题中去就完全反了
premise：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.
conclusion：Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.
顾客为了看明星喜欢高桌子&在高桌子上吃饭顾客呆的时间更短（这里面就有flaw：顾客坐高桌子的主要目的不是吃饭而是看明星，那么在桌子上呆的时间不是更长么？）所以应该是C it gives reason to believe that it is likely that a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering
