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?

请教一道JJ里面的题目(也是prep 2 - 11)

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!!!

前提: 94-96年,RDS radio Station(信号发出端)增加了,RDS feature(信号接收端)并没有增加,

结论: 能收听the special program的观众没有明显增加。

如果94年以前由于RDS radio Station(信号发出端)数量不够,覆盖面不广,导致很多RDS feature(信号接收端)不能受到信号,那么如果在94-96年扩充RDS radio Station(信号发出端)数量,使得大部分RDS feature可以接受到信号,尽管RDS feature数量没有增加,观众也会增加。这是原文中存在的逻辑gap。

正是将A去非的内容。

感觉D应该是一个Support 说没有RDS ferture的人都不能收到RDS radio Station发出的节目,正好支持了RDS feature没有增加,the special program听众就没有增加这个推理逻辑。

还有一些回答,请参考。

这是PREP2的第11题,请楼主改一下标题  PREP2-11,便于以后其他战友的查询。

非常非常感谢:)

谢谢版主的答复,我理解的了为什么A是一个assumption。可是还是没有解决为什么D不是assumption,如果我们把D取非,那么得到的结果是,没有radio的人,也能收听到节目,那不就是weaken了原文的结论了吗?因为收听人数不一定和radio的数量一致。说不定94年一个radio cover 3个audience,96年cover 6个audience? 请指教

另外,我看过了,这道题目确实是07年五月份的JJ,好奇怪啊,什么时候考试的时候也会有prep的题目了?不过我会改一下题目的,两个题号并列,呵呵。

考试的时候有可能会出现GWD和PREP:)

我自己感觉其实D 就是在重复原文的第一句话:) 大家一起帮忙讨论一下吧。
