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.

上面这句话是什么意思阿？有谁可以翻译一下？A是正确答案

1994年之后在V地新增的RDS电台当中，几乎不存在向从前没有被RDS电台覆盖到的地区中拥有RDS接收装置的人群播音的。

因为题目中给出了信息，说接收装置的数量没有增加，但是如果覆盖地区和人群范围扩大，比如1台接收装置从前一个人用，现在一家人用，甚至一村人用，自然会削弱题干中的结论，所以需要选项A的假设来支撑。
