Jennifer: Video rental outlets in Centerville together
handled 10,000 fewer video rentals in 1994 than in 1993. The decline in rentals was probably due
almost entirely to the February 1994 opening of Videorama, the first and only
video rental outlet in the area that, in addition to renting videos, also sold
them cheaply.
Brad: There must be another explanation: as you yourself said, the decline was on the
order of 10,000 rentals. Yet Videorama
sold only 4,000 videos in 1994.
Which of the
following, if true, would most seriously weaken the force of the objection that
Brad presents to Jennifer's explanation?
(A)
In 1994 Videorama rented out more videos than it sold.
(B) In 1994
two new outlets that rent but that do not sell videos opened in Centerville.
(C) Most of
the video rental outlets in Centerville rent videos at a discount on certain
nights of the week.
(D) People
often buy videos of movies that they have previously seen in a theater.
(E)
People who own videos frequently loan them to their friends.
