1 收听RDS广播的人数没有大量增长是因为96和94年装有RDS的radios数量一样.问假设.下面是原题
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.
(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.
答案A . 看不懂A选项, 我觉得D 对呀, 96年V地区的居民没有RDS的就不可能收听94年后开始播音的RDS电台播出的任何节目, 那么RDS的radios数量一样, 收听RDS广播的人数没有大量增长
2.司机3%安有RD, 被开罚单超速的司机33%安有RD. so安有RD比没安的更可能超速,问假设
A recent report determined that although only three percent of drivers on
The conclusion drawn above depends on which of the following assumptions?
(B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
答案B, 我不理解, “被开罚单超速的司机比没开罚单的更可能超速”->是想说明没开罚单的司机超速的可能性小吗?不能说明问题呀!

我觉得D就是把已知的条件重复说了一遍。已知里已经有"RDS的广播只能由有RDS接收器的收音机接受。" ‘Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive’所以D是已知，不是假设。
A 假设：很少（甚至是没有）RDS电台在1994后，在1994以前没有被RDS电台覆盖过的V城的区域里广播。说白了就是：1994年以后，RDS的广播覆盖的人口没有更大。
因为在1994年前，有RDS收音机的人可能因为他们所在区域没有RDS电台而无法接收RDS信号。

这道题是OG10-171的原题。 关键在选项里的regularly 。 你可以自己去看OG的解释。
