标题: 求助prep逻辑题一道~ [打印本页] 作者: coffeeqoo 时间: 2012-4-8 10:50 标题: 求助prep逻辑题一道~ 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 答案是C，但不太理解其含义~作者: lijiazhou 时间: 2012-4-8 11:01
尝试这解答一下：
这个题 Conclusion:if the Hollywood replaced some ofits seating with high tables and stools, its profits would increase. Premise: 1 many customers come to watch the celebrities who frequent the Hollywood,and they would prefer tall tables with stools because such seating would afforda better view of the celebrities Premise: 2 diners seated on stools typically do not stay as long as diners seatedat standard-height tables
这里的premise1 and premise 2 之间有个gap， 就是prefer tall tables 的人和 diners seated on stools typically 的人是不是相同的人，如果prefer tall tables 并且seat shorter那么可以make profits，但如果prefer tall tables但是还seat longer的话，是不是就影响了profits啦，而C选项就是表示这个意思
可能楼主会觉得D选项也跟profits有关，但是由于spend less time 可能导致后来的顾客数量增加的话，是不是也可以make profits，所以这个选项不能weaken.作者: alandiyer 时间: 2012-4-24 11:56
同错的人飘过。。。分析D得到的结果，是由于存在翻台率和点菜量的tradeoff，所以不能确定是否削弱。作者: huyuhan7 时间: 2012-5-18 00:10
