[求助]请教一道prep逻辑题

Jennifer:Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.The decline in retals 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，想不通。。。请高人指教！

转化为中文你就明白了：

Jennifer:今年影碟租赁市场比去年较少很多，主要原因就是，那个新开的店，不仅租，还便宜卖！

Brad:但是它只卖了4000张影碟，可是租赁市场却下降了10000啊！

Jennifer：买的人是不多，但他们不仅自己看，还借给朋友看。他的朋友不就不用再租了么？（答案E）

你的字号太小，下次请调大些。这次我已经替你改了。
