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.

答案是E，但是为什么A不对？

J的观点是开新店导致旧店业绩差，那A选项是支持J的观点的，也就weaken了B的观点。

是不是因为整个centerville的vedio rentals少了10000，而这个统计的10000是把新开张的这家店的vedio rentals也加上之后算出来的。

J: 相比来言少了10,000 rentals的业务，原因是： 开了一家新店，不仅租，还便宜地卖。

B： 这家新店就卖了4000张碟子，远小于你10，000的量，所以另有他因。

B在反驳时做了一个假设：这4000的sold不可能导致10,000的rental丢失。

E则攻击了这一假设：很多人买了碟子互相传阅，那很可能就是因为这4000张sold引起的
