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  我不太懂这道题问题的意思

A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the maximum possible price for such a product.  But large profits on the new product will give competitors a strong incentive to quickly match the new product's capabilities.  Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

In the argument above, the two portions in boldface play which of the following roles?

(A) The first is a consideration that has been raised to argue that a certain strategy is counterproductive; the second presents that strategy.
(B) The first is a consideration raised to support the strategy that the argument recommends; the second presents that strategy.
(C) The first is a consideration raised to explain the appeal of a certain strategy; the second presents that strategy.
(D) The first is an assumption, rejected by the argument, that has been used to justify a course of action; the second presents that course of action.
(E) The first is a consideration that has been used to justify pursuing a goal that the argument rejects; the second presents a course of action that has been adopted in pursuit of that goal.

答案是C

Transnational cooperation among corporations is experiencing a modest renaissance among United States firms, even though projects undertaken by two or more corporations under a collaborative agreement are less profitable than projects undertaken by a single corporation.  The advantage of transnational cooperation is that such joint international projects may allow United States firms to win foreign contracts that they would not otherwise be able to win.

Which of the following is information provided by the passage?

(A) Transnational cooperation involves projects too big for a single corporation to handle.
(B) Transnational cooperation results in a pooling of resources leading to high-quality performance.
(C) Transnational cooperation has in the past been both more common and less common than it is now among United States firms.
(D) Joint projects between United States and foreign corporations are not profitable enough to be worth undertaking.
(E) Joint projects between United States and foreign corporations benefit only those who commission the projects.
答案是C  我不太懂C选项是什么意思呢

你可以看看PREP的CR的详解啊
第一题是说，大家来H看名人，喜欢做高台子，但是一般做高台子的人吃饭时间比标准台子少，所以说这家饭店用了高台子就利润减少。问错误
A\B都是说名人的，显然无关
C这个说来这里看名人的吃饭的做高台子的人是那些generation的例外，正好和原文那个typically对应，我是这么觉得啊...
D加强了原文
E无关
