[CR. ] OV 47
In the past most airline companies minimized aircraft weight to
minimize fuel costs.
The safest airline seats were heavy,
and airlines equipped their planes with few of these seats.
This year the seat that has sold best to airlines
has been the safest one—
a clear indication that airlines are assigning a higher priority
to safe seating than to minimizing fuel costs.
Which of the following, if true, most seriously weakens the argument above?
(A) Last year’s best-selling airline seat was not the safest airline seat
on the market.
(B) No airline company has announced that it would be making safe seating
a higher priority this year.
(C) The price of fuel was higher this year than it had been
in most of the years when the safest airline seats sold poorly.
(D) Because of increases in the cost of materials,
all airline seats were more expensive to manufacture
this year than in any previous year.
(E) Because of technological innovations,
the safest airline seat on the market this year weighed less than
most other airline seats on the market.
OA:E
Ｅ不會有違背前提的問題嗎？
我選Ｂ，這樣不是直接反駁結論嗎？
