The Comfocar company manufactures a
sedan that can drive comfortably at 80 miles
per hour. A rival company, Turbocar, recently
introduced a comparably equipped sedan
that can drive comfortably at up to 110 miles
per hour. Turbocar claims that its sedan will
outsell Comfocar's sedan because the
Turbocar sedan can get customers to their
destinations in comfort much faster than can
the Comfocar sedan.
Which of the following, if true, casts the most
doubt on Turbocar's claims?
A. Customers in surveys consistently rank
comfort among the most important
criteria in purchasing a car.
B. Many road surfaces are engineered to
allow comfortable driving at speeds up to
120 miles per hour.
C. Automotive safety experts state that it is
not safe for any car to be driven faster
than 100 miles per hour.
D. Comprehensive research has determined
that while the Turbocar model has faster
acceleration and a higher top speed than
the Comfocar sedan, both cars show
approximately the same fuel efficiency.
E. Nowhere in the main marketing areas for
these two car companies is it legal or
practical to drive faster than 70 miles per
hour.
