Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.
(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.
(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.
(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

答案:B...我選C
我想說C支持採用新方法,因為它比較不易損傷,採用新方法具有長期經濟效益
不懂為何選B
謝謝回答

[hey]

你翻錯(C)選項了...
(C)選項是說, 新的coating對於侵蝕比起原來的primer提供較少的保護.... 那麼如果這樣說的話, 反而不是支持而是反對囉....

(B)選項是說, primer的重量比新的coating要重, 而這種多出的重量會影響飛機的載運量, 因此如果用新的coating的話, 飛機的載運量便會比原本的多, 因而對於飛機的長期經濟效益有利, 因為可以載更多的人而賺更多的錢嘛

所以(B)會是較好的答案

哈哈 對耶!我瞎了!謝謝喔
