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.

答案为E，我选A。我怎么觉得两个选项都起削弱作用。

A中Videorama不仅有卖出Video，也有出租Video啊，如果出租的比卖的多，就不能只拿卖出400个来说明问题。应该拿“出租数量”+“出售数量”来说明问题，削弱原文

E也是对的，也起削弱。说Videorama卖出的Video后，Video被消费者继续转租给朋友，那就拿“出售数量”+“转租数量”来说明问题。而非只拿出售400来说明问题。削弱原文
