11.(24915-!-item-!-188;#058&001837)

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.

此类assumption题目，取非是个好方法吧
A说，即便有，也是很少量的RDS广播站在94年以后开始对已经有收音机但是之前没信号的地方播音。
对这个假设取非，就是有大量的94年以后开始播音的电台呢，实际上这些电台是对已经有了收音机，但是之前没有信号的地方播音。则推出，V国听众数量其实是增加的，跟原文结论相反不是么？！

D，我不太明白D想要表达什么。我理解D就是说：96年，没有能收RDS信号的收音机的v国人就不能从94年以后兴建的广播站那里收听到节目了。
但我不太明白D想表达什么，也不知楼主如何理解这个选项是原文的假设的。欢迎解释一下你的想法，我们在讨论？？

LS is right. A is the answer.

What it says is that all the newly added station after 1994 still broadcast to the old listeners instead of reaching more NEW listeners. This is the assumption required for the argument.

D is repeating partially the first sentence of the arugment, which is just a fact. Anything mentioned in an arugment is not an assumption. Assumption is an untold premise.

不好意思扒一下帖子，我理解的是题干说，94年以后没有什么人买了新设备，所以没有新的人收到special radio，那这个逻辑很完整，不需要选项A的假设来depend呀，因为没有人有新设备，所以能不能覆盖到没有关系呀
