标题: 求解一道PREP题,答案有点绕

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.

所以 不增加
