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) 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 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.

这道题的逻辑意思是什么呢,我选B,答案是A.
