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?
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.
In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
Equipping a radio station with RDS technology does not decrease the station's listening area.
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.
The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.
类比/因果
1994VS1996
因为RDS广播机器的数量在1994与1996相似→V收到特别信息（RDS）（划重点！！！）的人不会特别增加，也就是一样
ASSU，搭桥（取反容易），增强，寻找二者相似性
A、拆掉双重否定，1994年后，所有RDS广播站已经覆盖了所有拥有RDS机器的人，这是1994和1996的相似点，因为已经全覆盖了，所以不会特别增加，CORRECT
B、在1996所有在收听范围中的人都有RDS机器，重复原文
C、装备RDS让广播站的收听范围不会减少（广播站与收听范围，而非机器与收听范围的关系），（且文中需要证明的是不会增加，这里说的是不会减少）
无关
D、在1996，没有RDS机器的人，没办法收到在1994之后装备RDS的广播站放出来的任何信息，本来没有RDS的人就不会收到RDS信息，重复原文，且与题目中ARGUE的人群不一致，无关
E、RDS广播不是统一输出内容，反向，削弱了
