1. 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 Verlanders 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 Verlanders 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.


My Take:
Premise 1: Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.

Premise 2: Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.

Premise 3: since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994.

Conclusion: the number of Verlanders receiving the special program information probably did not increase significantly

If RDS is implemented on a present non RDS technology radio station (this is possible as the argument simply says "the number of RDS radio stations (not new stations) in Verdland increased from 250 to 600". what if with the installation of RDS the listening area of present stations decreases. Even if the no of number of Verlanders receiving the special program information increased because of the increase in the number of station, decrease in listening area would the number of Verlanders receiving the special program information and the effective increase would come down.


if any assumption that syas the stations’ listening area did not decrease, the reason for "why the number of Verlanders receiving the special program information probably did not increase significantly" would be simply " beacause people did not have radios equipped with RDS tecnology as the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994." This option eliminates any other possibility for the "not significant increase". I took C as a defender assumption but it is not the OA....plz help...
