求教prep上的一个问题啊，关于radio的

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?

Station数量多了接收器不变à接受info的人数量不变



(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.含有not,加上很长，优先选择，意思是few（理解为没有）S在94年后开始为原来有radio，但是原来的S不能达到的人播放对于这个解释不能理解

(B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS. 但是RDS数量没有增加，没比较

(C) Equipping a radio station with RDS technology does not decrease the station's listening area.没影响，没比较

(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.重复文章的premises错选

(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.没有对比

看了这么久，终于把这道题看懂了！
(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.（懂啦！很犀利哦。广播电台的范围扩大，同时安装有该设备的收音机数量不变，所以说听到该节目的人数不变。有没有跳跃呢？有的，如果之前有人有安装设备，但是也听不到呢？所以，假设是A：几乎没有新增的广播电台覆盖到以前有设备但是接收不到的人中去。取非：有广播电台覆盖到以前有设备但是接受不到的人中去，那么现在接收到节目的人就会增加了，削弱原文。）
(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.（要注意D这样的陷阱！D只是重复说了一遍原文第一句，不能算作假设条件！）
(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Necessary assumption. Use negation.

If you negate A), you have:

Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 DID NOT broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.

This is a double negative statement. If that is true, then almost all these stations broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations. In other words, stations reached out to NEW listeners! If so, the conclusion “the number of Verdlanders receiving the special program information probably did not increase significantly” is wrong. Thus, A) is the necessary assumption.

Thanks a lot!

SdcarNN能不能解释一下A的句子的成分，都看不懂他的主谓宾了~Thx in advance~

Few if anyof 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).

Thx~~SdcarNN~~

问下为什么C不对？如果说增加了RDS后范围变小了，即使问题变多，但是每个的listening area小了，所以对应的受众并没有increase.

few if any of如何理解？是此题的关键。

意思就是“几乎没有”，可以直接理解为“few of”。
