Ques 6:
6. 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
unusual weather.
(C) Mortality per passenger mile is lower for
air travel than for any kind of surface
transportation.
(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
of transportation.
(E) Last year the average number of
passengers per flown plane was
significantly lower than that of previous
years.
Ques 8:
8. Although most people know that exercise is good
for the body, few realize the extent to which it is
valuable to the mind. The blood circulates more
rapidly after physical exertion, thus allowing all
of the body’s organs to operate more efficiently.
This increased activity enables the brain to
receive more oxygen, thereby creating a higher
capacity for concentration.
The main point in the argument above is that
(A) the greater the amount of oxygen the brain
receives, the better the brain
functions.
(B) exercise is a mental, as well as physical,
activity.
(C) exercise helps the brain more than it does
the rest of the body.
(D) people can greatly improve their powers of
concentration by exercising more often.
(E) exercise serves more than one purpose.
I feel the answers to 6 & 8 must be D & B respectively whereas the answer key says they are A & E. Can someone elaborate on this?
