考古題Form33第16題
Car radiators have generaly been aluminum, not cooper, since the early 1980's, when many makers of radiators retooled their plants to suit aluminum, then cheaper than cooper. This year aluminum prices rose sharply; yet radiators are unlikely to revert to cooper because carmakers have exploited the much lighter aluminum radiators to design better-performing cars.

Q: Which of the following , if true, best supports the view that the author's prediction about continued use of aluminum in radiators is correct, but correct for the wrong reason?

答案是D
(D)This year's high aluminum prices reflect a temporary shortage , and prices are expected to collapse, stablizing at levels below those of the early 1980's.

我選了E
(E)When makers of radiators switched from copper to cheaper aluminum,radiator prices did not drop, because the manufacturers needed to recover the cost of retooling their plants.

這題我有些不明白題目意思,要我選出能支持繼續使用鋁的但是correct for the wrong reason???

其實我做題時也用刪除法剩下D E....

Car radiators have generaly been aluminum, not copper, since the early 1980's, when many makers of radiators retooled their plants to suit aluminum, then cheaper than copper. This year aluminum prices rose sharply; yet radiators are unlikely to revert to copper because carmakers have exploited the much lighter aluminum radiators to design better-performing cars.

Which of the following , if true, best supports the view that the author's prediction about continued use of aluminum in radiators is correct, but correct for the wrong reason?

(A) For a large segment of the car-buying public, the purchase price is by far the most important criterion in choosing a car.
(B) Leaving aside the cost of the material itself, the cost of making an aluminum radiator exceeds the cost of making a copper radiator.
(C) The great majority of car owners, having once gotten used to better-performing cars, come to value superior performance highly.
(D) This year's high aluminum prices reflect a temporary shortage , and prices are expected to collapse, stablizing at levels below those of the early 1980's.
(E) When makers of radiators switched from copper to cheaper aluminum,radiator prices did not drop, because the manufacturers needed to recover the cost of retooling their plants.



Ans : D

(A) 無關於 car price
(B) 範圍外
(C) 無關於 car owners
(D) Al 貴仍然用 (wrong reason), 因為高價為短期現象,長期價格低 (use of Al is correct)
(E) 無關於 radiator price
