请问这题到底是选择A还是D? 解析里面选择的是D,但是PREP资料里面显示的答案是A
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. |
