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?
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.
In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
Equipping a radio station with RDS technology does not decrease the station's listening area.
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.
The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

RDS电台广播特别节目信息，只有具有RDS特性的收音机可收到。 1994-1996年，B地RDS电台数从250增长到600.然而，由于96年V地RDS收音机数量和94年相同，收到特别节目的V地人数不会增长很多。
选项分析：
(A) 正确答案 -94年后几乎没有RDS电台传播到有RDS收音机而没有在RDS电台到达范围内的人；把双重否定去掉，也就是说有RDS收音机的人在94年前就在RDS电台范围内了，那再增加电台数，不会增加收听人数的可能性变大（相当于能够收听的人本身就在1994那会覆盖区域里面，再增加电台也没有什么效果）
(B) 96年大部分生活在RDS电台范围内的人已有RDS收音机；那应该收听人数会增加，削弱，排
(C) RDS电台没有减少收听范围；那应该收听人数会增加，削弱，排
(D) 96年，没有RDS收音机的人不能收到RDS电台在94年后的任何节目；谈的是没有RDS的人，文本说的是有RDS的人，样本问题，，排
(E) 96年V地的RDS电台不全提供同样类型的节目；谈节目类型 ，但是没有说节目类型跟收听有什么关系，排
