Rumored declines in automobile-industry revenues
are exaggerated. It is true that automobile
manufacturers' share of the industry's revenues fell
from 65 percent two years ago to 50 percent today,
but over the same period suppliers of automobile
parts had their share increase from 15 percent to 20
percent and service companies (for example,
distributors, dealers, and repairers) had their share
increase from 20 percent to 30 percent.
Which one of the following best indicates why the
statistics given above provide by themselves no
evidence for the conclusion they are intended to
support?
(A) The possibility is left open that the statistics
for manufacturers' share of revenues come
from a different source than the other
statistics.
(B) No matter what changes the automobile
industry's overall revenues undergo, the
total of all shares of these revenues must be
100 percent.
(C) No explanation is given for why the revenue
shares of different sectors of the industry
changed.
(D) Manufacturers and parts companies depend for
their revenue on dealers' success in selling
cars.
(E) Revenues are an important factor but are not
the only factor in determining profits.
