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.
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）
