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,为什么A不可以啊?e如果V租出了好多碟,也可能卖的少啊,从而weaken Brad提出的观点???哪位高人帮帮忙啊,感激不尽那~~!!!
