今天第一天看JJ,还有6天考试。碰到一道题目,不是很理解,请大家指教,谢谢拉 Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly. Which of the following is an assumption on which the argument depends? (A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations. (B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS. (C) Equipping a radio station with RDS technology does not decrease the station's listening area. (D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994. (E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming. 答案是A,我选了D。 题目说电台增加了但是radio没有增加,所以听众没有增加。问assumption。 我的思路是这里如果要weaken的话,可以说没有radio的人如果可以从有radio的人那里收听到RDS,比如在餐厅里听啊,电车里听啊,那结论就不存在了。所以作为assumption,只要把这个可能被weaken的点补上就可以了。所以我选C。对于A,我怎么觉得是无关选项呢? 请指教,谢谢拉!!!
