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.
A句我的翻译：很少装有RDS的从1994年后开始在V地广播的电台会广播给有装有RDS系统收音机的住在以前RDS系统到不了的地方的人。
中等难度的逻辑思维题目。题目信息：Verdland的RDS radio stations 的数量从1994年的250增加到1996年的600，而Verdland的RDS-equipped radios的数量保持不变。因而接收special program information的Verdlander的人数没有增加很多。问结论是基于哪项假设。
station数量增加，说明RDS的覆盖范围增加了，而RDS-equipped radios的数量不变，则有两种可能性，一是receive special information的人数不变，因为所有具有rds radio的人在之前处于覆盖范围内，增加范围对他们无影响；二是receive special information的人数增加，因为之前不再station覆盖范围内的rds radio现在处于station的覆盖范围。由此可知，正确选项是A。
做题思维要严谨，自我劝诫！

If any是插入语，可以忽略。意思是94年后，几乎没有电台广播到［那些之前收不到电台但有设备的人］.类比推理
1994，装备RDS的radio数量，收到特殊信息的V人数量
1996，装备RDS的radio数量同上，收到特殊信息的V人数量同上
选项里找出现1994和1996，且有一个共同点的。A选项就是电台广播的接收点数量一样(因为之前有设备收不到的人现在还收不到）
D只是重复说了一遍原文第一句，不能算作假设条件
错了，看了A一眼就飘过去了，没有读懂A的含义
Few（if any插入语）of the RDS radio stations（定语从句that began broadcasting in Verdland after 1994）broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations
大意是：94年后，几乎没有电台广播到［那些之前收不到电台但有设备的人］
取非：94年后，有一些电台广播到了原来收不到电台但有设备的人。
所以接受到这些电台节目的人增多，对文章结论起削弱作用。A正确。
