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.

答案A是排除出来了。想知道A到底说了什么意思啊？？？

A说的就是虽然新建的基站很多，但是1994年时候，基本上已经全覆盖了，后来再加的基站，并不能带来更多的听众。

我认为A是说：

1994年后，几乎没有radio station覆盖到那些人，也就是以前虽然有radio with RDS但不在服务区的人

也就是说：增加了那么多station像跟没增加一样！于是听radio的人没怎么增加

D选项提到who did not own radios with RDS和本文无关，本文只关心有这种radio的人
