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， 但是我选A。
E选项提供了另一种解释rentals下降的可能性，这是支持第二人的说法，但题目要求undermine第二人的观点，求问为什么E是正确选项？
第二人认为，sold的数量只占rentals下降量：10000的一小部分，因此还有其他explanation. 问削弱第二人观点。
我认为，第二人用sold量来解释rentals数量下降，这明显是有问题的；A说V店的rental数量大于sold数量，也就说，有可能rental下降量10000里有大于4000是被V拿走的，这就顺理成章反驳了第二人的观点。

如果问题问的是support, 那选E是对的。

求高手解析，不吝赐教！！！感激不尽！

J：C城影碟出租店在1994年的出租量比1993年的出租量下降了10，000次。下降的主要原因是因为当地唯一一家租碟店V开业时，除了租碟外，它还以更低的价格将碟片便宜出售
B：应该还有其他解释，正如你所说，租碟量减少了10，000次，但是V店1994年仅仅卖出了4，000张碟

E. 拥有碟的人们常常把他们的碟租给他们的朋友 （削弱结论：卖得多，可以从朋友那里借到，所以租量减少了）
