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.
E. People who own videos frequently loan them to their friends.

我不明白的一点是：B反驳J时强调yet V sold only 4000 videos. 这与rental有关系吗？Rental下降10000与sold多少没关吧！ 不明白反驳的点在哪！ 有可能卖的少租用的多呢？这样就

题目B反驳我觉得不可思议 没有反驳的效果。

Only a reduction of 10 percent in the number of scheduled flights using Greentown's airport will allow the delays that are so common there to be avoided. Hevelia airstrip, 40 miles away, would, if upgraded and expanded, be an attractive alternative for fully 20 percent of the passengers using Greentown airport. Nevertheless, experts reject the claim that turning Hevelia into a full-service airport would end the chronic delays at Greentown.

Economist:  On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000.  A new therapeutic program can significantly reduce an elderly person's chances

of falling.  Though obviously desirable for many reasons, this treatment program will cost $12,500 and thus cannot be justified.  fall这里是什么意思   连贯不上

我发现逻辑读懂了就对，读不懂就真的靠运气了，希望知道的朋友可以帮忙解释下~~~  感激不尽

For Brad, his opinion is the same as yours-有可能卖的少租用的多呢？. His line of reasoning is the new shop sold less amount of videos than that of video rentals reduced from 1993 to 1994.  Thus, the opening of Videorama could not be the reason for the decrease of Video rentals.

fall means "跌倒“。
