An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today, compared to no more than a third for any other manufacturer.

Which of the following, if true, most strongly supports the advertisement’s argument?

(A) After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.

(B) The number of automobiles built by Deluxe each year has not increased sharply since 1970.

(C) Owners of Deluxe automobiles typically keep their cars well maintained.

(D) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.（B）

(E) Deluxe automobiles have been selling at relatively stable prices in recent years.

请问B是怎样支持的呢？

B的支持在于:由于自70年代以来,Deluxe所制造的汽车由于过于老旧而被淘汰的只有一半(原文说在路上跑的还有一半,反过来说就是淘汰的也是一半)既然只有一半的淘汰了嘛,如果按照经济学里supply和demand的思路;淘汰了一半,那demand就只有这一般的,自然supply就不会高咯,这也就是为什么自1979年以来,它所生产的汽车量每年不会有很高增站的原因.

这个答案和原文的主题趋势是成一个趋势,不矛盾的.所以是支持的.

你可能把support ad和support原文意义混淆了, 答案只要和原文意思一致就可以了.并不在乎实际的逻辑意义是否正确.当然这样的广告创议不好.
