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.

为什么答案是A？谁能翻译一下A选项的意思？
Many thanks!

这题是说，那种特殊节目增多了，可是装特殊接收器的数量并没有增多，可以得出结论收听这种特殊节目的人数没有增多。基于什么assumption？
A的意思是说，节目没有reach到新的区域。
因为如果以前有些人是装了仪器的，但是因为节目传播不到他们那个区域所以没听，现在的新节目能传播给他们了，那他们就能收听。这种情况下即时接收器数量没有增加（因为他们以前就装了），听节目的人也在增多。
然后A选项排除了这个可能。

后来自己看了几遍就明白了~这题关键是在A中的few，以至于我先没有读懂A的选项~
谢谢啦！

关于选答案的我自己理解是，文中说因为持有R的人没变 所以接收到information的人不会有大的增加。注意最后一句的最后一个单词significantly
我之前选D，看到论坛上的解释是说D重复了文中的话
今天再看的时候突然发现那个few 和significantly的关系
文中只是说不会有大的增加而不是完全没有增加
所以D不对
