两道PREP求解

之前有搜过前人成果，发现自己的PREP题目的编号和大家的不一样，唯有post出来请高人解答。

Q3.  p2-cr       11.   (24915-!-item-!-188;#058&001837)

 

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.

 

Which of the following is an assumption on which the argument depends?

 

(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

(B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.

(C) Equipping a radio station with RDS technology does not decrease the station's listening area.

(D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.

(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Q19.       p2-rc      17.   (26864-!-item-!-188;#058&003368)

 

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

1，

V这个城市，RDS格式广播节目多了，但是RDS接收机没变化，因此收到节目的人没变化。

A说，没有RDS格式广播节目是播给（之前收不到信号的地区的）（且有RDS接收机的）人们的。

也就是说有可能之前有些地区的人有RDS接收机，但是住在收不到信号的地区，但是现在能收到信号了。

2，

群众要坐高桌子，想要看明星，坐高桌子的人用餐时间还短（这样饭桌率就快嘛），因此餐厅要准备一些高桌子。

文章中提了两个作者认为应该换高桌子的理由，I 群众喜爱高桌子，看明星用。II 高桌子的待得时间短吃饭快。（可能是因为不舒服吧）

但是！作者没有想到的是，这两条是有可能冲突的。I 中的那些群众有可能为了多看明星，而不会很快走，即使不舒服我也不走。（即 “待得时间短吃饭快”就是“generalization about lingering ”，而群众不会这么做，他们可能就对一直坐在那里看明星看很长时间，因为文章中说了，群众是为了看明星来好莱坞的啊）
