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?

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.、
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). 这个是这样断句的 极少电台(有rds系统的)(94年之后的) 播放对 听众(有rds的)(住在一些地区《以前不能收到rds的》)
验证假设可以用取非削弱 取非后, 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). 有的在1994年之后成立的r电台向有r设备但是以前收不到电波的地方的人们播放。 其实这个前提是数量上:电台变,收音机不变,结论收到的不变。由收音机不变到接收的人不变,就隐含着,有收音机就有收听这个假设。比如有的地方收不到信号,有收音机也没用啊,这个选项就是架这么个桥。
