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.

正确答案（E）我怎么不觉得是weaken呢？这不正就是Brad结论说的"another explanation"，明明是加强了啊？
求解答~~~

买了碟的人会把碟借给朋友，那很多人就会既不买也不租了

还是不明白。。。既不买也不租，说明rental下降不是新开的店的影响，这明明是在加强，不是削弱嘛。。。

买了碟的人会把碟借给朋友
要注意是，买了碟片的人，不是别的人。。。。

买了Vedio=》减少了rental；
买了Vedio又借给了朋友=》朋友也不去租了=》减少了rental;

削弱了B，加强了J

J： premise： Videoram（ the first and only video rental outlet that rent+ sell vedio) opened in 1994
   conlusion: decline in retal(10000） was due almost entirely to the Videoram
=》翻译成中文就是前提：新开的V出了租碟片，还卖碟片
                           结论:  新开的V 是造成出租总量下降的主要原因

B： counterpremise to J's conclusion: the decline was  10,000 rentals，but Videorama sold only 4,000 videos in 1994
         => B用来反对J的结论的前提：出租总量下降了10000，但是V只卖出了4000
B的intented meaning是，仅仅4000的量，不能说明10000的decline in total rentals 完全是因为新开的V卖出了碟片，还有6000的减少量无法解释，从而反驳J的结论

要削弱B的反驳，就是要说明J的论证是对的，B的论证是错的，要证明另外那个6000减少的量也是因为V的开张

E项，因为人们买了vedio之后会借给朋友，那么整个rental market的总量就减少了，整个减少的6000不是直接转移到购买上了，而是由租赁市场变成了朋友间的相互借。
   简化之后就是：因为买，所以朋友之间相互借，那么Vedio rental total就少了
               逻辑链： V open=> people buy(4000)=> lend to their friends(6000)
                        加强了V open和 decline in rental 的因果关系
