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.
Brad推論的意思是: 減少的6,000片出租量並非Videorama出售Vedio造成
重點在於出售Vedio
Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?
要weaken Brad推論, 答案要找減少的6,000片出租量是Videorama出售Vedio造成
(A) In 1994 Videorama rented out more videos than it sold.
題幹論點著重在討論出售量, 拿出租量和出售量兩個相互獨立議題是 無關vs有關比較
(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.
這裡用do not sell跳脫議題焦點無法weaken, 要weaken除非兩個outlets也在賣vedio影響出售量, 注意整個重點在出售量
(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.
這句說明減少的6,000片出租量是Videorama出售Vedio造成
