Jennifer:  Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.  The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.

 

Brad:  There must be another explanation:  as you yourself said, the decline was on the order of 10,000 rentals.  Yet Videorama sold only 4,000 videos in 1994.

Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?

 

(A) In 1994 Videorama rented out more videos than it sold.

(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.

(C) Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.

(D) People often buy videos of movies that they have previously seen in a theater.

(E) People who own videos frequently loan them to their friends.

这个题目是问哪个是削弱B的结论吧？

我选择A，可是答案是E。B认为有其他原因解释RENTAL的减少而不是F的进入，因为F只买了4000张。那E不真好是他因支持了B么？请大家帮忙

E的意思是人们买了碟以后经常借给朋友，间接导致租碟的人更少了。这题关键点是碟可以卖所带来的间接变化

所以选E
