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.
我这月考，马上了，跪求大牛解答，题干看明白了，就问a的意思。。。

有点绕 意思就是说 有一些人原来是在电台覆盖不了的地方即使有radio但是也接受不了因为不属于电台的覆盖范围 而在1994年以后 这些电台也几乎没有向这些地方广播。我的理解
取非一下：就是说 他们会像以前覆盖不了但是有接受装备的人发送广播==> 那么收听群众就应该是扩大了 因为他们本来的设备是可以接受的 只是地域范围不行。结论不成立 所以此为答案
