LSAT-2-4-24再次请教，非常谢谢

every time you see " however" pay close attention to the immediately following content.

However, the catalytic converter, invented in 1967, enabled automakers to meet the 1970 standards efficiently.

Since the former grounds of being both economically infeasible and enviornmentally unneccesary have been denied by new tenchique invention in 1967, the current similar argument fails to contain any legitimacy.

NO! (sorry : ), the answer is (D). (E) is not the answer b/c there is an unwarranted assumption that similar technology will be making breakthrough in the future. There IS an evidence offered to deny the automakers' past claim, but absolutely no single evidence is provided here to prove wrong their current one, just a comparsion is made, which is why (D) is the official answer.

Which one of the following most accurately expresses the method used to counter the automakers’ current position?

Trapped by E? probably because you already forgot the question when you went a long way to E

呵呵， 恳请楼主发贴的时候最好把正确答案贴出来，1，本人长时间没做LSAT了， 所以对很多题已经比较生疏了。 2， 时间的原因再加上本人比较懒， 所以会经常照着你给的答案解释。

LSAT的答案其实就是这个特点， 如果你想证明它是对的， 怎么找你都有理由。 所以， 一个习惯的做法是想答案是如何错的， 而不是如何对的。

翻了一下自己以前的作题记录， 发现我的最初选择是D.
