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 stationâ€™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.

D.
Assumption is that, Radios not equipped with RDS technology will not be able to access the RDS tech based broadcasting.

It has to be A.

D is wrong because it is already stated in the question stem.

By using negation theory the answer is A.

D seems to be the closest to my original answer before seeing the answer choices.

The assumption is that somebody that doesn't have a radio with RDS technology will not go to their friends house (or to work or any other place) to listen to the broadcast information.

If D is not true, then somebody with a radio without RDS could go next door to hear the broadcasts.

Choice between "B" and "D", and D wins it as the assumption is "nobody can receive the broadcase without RDS". Apply the "negation" test to each of the statement, i.e., negate all the choices mentioned and the one which affects the conclusion is the assumption.

Thanks for explanation. Originally I selected "D" but GMATprep say "A". I don't understand why.

D is the correct assumption because even though # of RDS equipped radio station increased, the user base did not because it was saturated in 1994

Seeing that the OA is A,

The only reason I can think of why D is incorrect could be that D assumes that new radio stations that were added after 1994 cater to the same areas where the existing stations cater to, hence no growth in user base...which may not be correct.

A is saying that few of the new stations catered to users who did not have access to RDS stations - which is the assumption that D assumes!
