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?

a)In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
b)Equipping a radio station with RDS technology does not decrease the station's listening area.
c)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.
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.
e)The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

Answer is C. Here is why?

A -- This statement only talks about the year 1996 and there is no comparison with the year 1994 (the time when the number of RDS stations increased). Hence this is ruled out.

B -- Not in scope.

C -- Strong candidate since this options rules out/significantly reduces the possibility of the newly added RDS radio stations having greater reach.

D -- Irrelevant. (Also is very confusing)

E -- Again only one of the year is noted without any clear comparative analysis being brought forth between 1994 and 1996.

Hence answer is C. Hope my reasoning is sound.

C it is.

It rules out the possibility that the new stations are build on previously inaccessable RDS owner and thus could bring in more people to listen to the program.

Think about what's being said.

RDS Stations: Increase
RDS Radios: Same
This means: Number of people receiving special programs didn't increase.

If the stations increased but the radios stayed the same, then the stations must be broadcasting to the same people who had the radios before. So the RDS broadcasts in new places is comparatively low.

a)In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS. Not given. This is not a NECESSARY condition.
b)Equipping a radio station with RDS technology does not decrease the station's listening area. We know nothing about this. Out-of-scope.
c)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. This is directly in line with what we expect.
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. Out-of-Scope again.
e)The RDS radio stations in Verdland in 1996 did not all offer the same type of programming. Irrelevant.

This is a very tough one, thanks for attempting. For D, isn't that stated in the stimulus? I chose C, but I am having a tough time explaining this one.

TS: What is the source of this question?
