The decline in rentals wasprobably due almost entirely to the February 1994 opening ofVideorama, the first and only video rental outlet in the area that, inaddition to renting videos, also sold them cheaply.
[size=14.000000pt]Brad: There must be another explanation: as you yourself said,the decline was on the order of 10,000 rentals. Yet Videorama soldonly 4,000 videos in 1994.
[size=14.000000pt]Which of the following, if true, would most seriously weaken theforce of the objection that Brad presents to Jennifer's explanation?
[size=14.000000pt](A) In 1994 Videorama rented out more videos than it sold.
(B) In 1994 two new outlets that rent but that do not sell videosopened in Centerville.
(C) Most of the video rental outlets in Centerville rent videos at adiscount on certain nights of the week.
(D) People often buy videos of movies that they have previously seenin a theater.
(E) People who own videos frequently loan them to their friends.
答案选E。但我不太理解。请各位大神指教。谢谢拉～[size=14.000000pt]

Jennifer的观点是因为有 video rental outlet 便宜卖video 所以租的人少了，Brad的反驳是卖的只有4，000而租的少了10，000，问题就在于假设看video的需求不变，还有6，000的需求哪里去了？所以Brad反驳的点在于两个数量不一致，他认为Jennifer的观点无法解释还有6，000的decline是因为什么减少了，而E选项解释了这6，000是怎么少的，这6，000原本应该去租video的人因为(E) People who own videos frequently loan them to their friends.从而可以从朋友处得到，也就不需要去video rental outlet 去租了作者: zhou307 时间: 2015-7-21 19:55
