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.
答案為E
對題目理解的意思是-->去年大部分航空公司減少重量減低燃料成本 最安全的航空公司座位是重的,而大部分航空公司很少提供重的座位
今年所有航空公司(airlines)賣最好的都是最安全且最重的座位，表示航空公司認為安全比減低成本重要
1.想知道為何B不對呢 ? 既然今年沒有航空公司會做更多的安全座位 不就可以否定了?
2.為何E只說the safest airline 改變機位重量就可以當否定呢? |
