再问prep1-10，新观点，请指教

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，我选A。理由：E说买的人会将录影带再租给别人，但我觉得租来租去，录影带的内容也仅限于那4000盘，而如果有人想看第4001盘的内容，则还是要去租才能看到。也就是说，如果那10000盘的内容每盘都不一样，则卖出的4000盘，以及再转租给别人，都不会影响其他6000盘的出租量。除非1993年出租的10000盘内容是一模一样的。而A，则无论那10000盘内容是否一样，都会削弱。不知我的想法对不对，请高人指教。

而A，则无论那10000盘内容是否一样，都会削弱。

一语中的，谢谢。版主辛苦，凌晨还上来答题，赞

文章问的是削弱Brad的论据。。。。

我怎么觉得A是个无关选项呢

本题的问题

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

那么就是weaken B 然后找B的意思: rentals少了10000 而我只卖了4000 结论是:这个减少与我卖4000无关

A做了一个无关的比较 也就是说这个比较与"减少10000是因为卖4000"这个逻辑过程无关

而E说 不是的 与你卖4000是有关的 customers就是买了以后借给朋友们导致他们都不来店里rent了 这样就让我的rentals损失了10000
