大家帮忙看看这道题。

Gas station owner: Increased fuel efficiency reduces air pollution and dependence on imported oil, which has led some people to suggest that automobile manufactured should make cars smaller to increase their fuel efficiency. but smaller cars are more likely to be seriously damaged in collisions and provide less protection for their occupants. Greater fuel efficiency is not worth the added risk to human lives; Therefore, manufacturers should not seek to increase fuel efficiency.

the reasoing is flawed because the argument

A) presumes, without providing justification, that it would be impossible to reduce the likelihood of dangerous accidents for small cars，

B) concludes, on the basis of the claim that one means to an end is unacceptable, that the end should not pursued.

答案是B。可为什么A不对呢。作者的假设不就是降低小车的安全性是impossible的才得出的这样的结论么？而这个假设有可能是错的啊。所有flaw在这里。不对么？

哪位朋友能指点一下迷津啊，多谢了！

It does not talk anything about whether it is possible or not to reduce car accidents, its issue is how to increace fuel efficence. One means which is making small car is unacceptable(less protection to occupants), but it does not mean that fuel efficency should not be pursued.

there is no assumption that it is impossiable to reduce the likelyhood of dangerous accidents for small car, it just says that smaller car are more likely to be seriously damaged, so it is not worth the risk.
