如何理解OG-141飞机安全和成本题

141. 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.

141.

If the safest airline seats are now among the lightest, as choice E says, then buying them could be part of a strategy of minimizing fuel costs, rather than indicating a shift away from that goal. Choice E, therefore, is the best choice.

如何理解此题呢？

airlines are assigning a higher priority to safe seating than to minimizing fuel costs.

这个是结论. 找个选项反对这个结论就好了。要么说

This year the seat that has sold best to airlines has been the safest one这个EVIDENCE说明不了航空公司注重安全，要么说这个EVIDENCE还是间接支持航空公司要省油.

minimize fuel costs的前提是aircraft weight ,找个变轻的就可以了。
