Air travel is becoming increasingly more
dangerous. In the last year there have been
seven major collisions resulting in over 700
deaths, more deaths than in any previous year.
Which statement, if true, would most weaken
the argument above?
(A) Since the volume of air traffic has been
increasing all the time, an increase in the
number of deaths due to collisions does
not necessarily mean greater danger.
(B) The increase in collisions can be explained
by statistical coincidence, hijackings, and
(C) Mortality per passenger mile is lower for
air travel than for any kind of surface
(D) The increase in deaths due to collision in
air travel has proceeded at a rate identical
to that for deaths in all other major forms
(E) Last year the average number of
passengers per flown plane was
significantly lower than that of previous
