### HideShow timer Statistics

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.

I am totally lost with this one.

How will more Verdlanders recieve specific programs from RDS stations?

Because, more number of Radios means, more users, and more recievers of special program information.

2. More coverage in areas that were not covered before.

There is a possibility that some owners of RDS equipped radios live in remote areas where they dont recieve special programs due to lack of coverage. If the new radio stations can cover them, then there can be more recievers of special program information.

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

For the conclusion to be correct, the number of radios and areas covered should be the same. Option A provides the needed assumption.

A !

RDS radio stations didn't broadcast beyond a limitted area so the number of listeners didn't grow ....
