In opposing the 1970 Clean Air Act, the United States automobile industry argued that meeting the act’s standards for automobile emissions was neither economically feasible nor environmentally necessary. However, the catalytic converter, invented in 1967, enabled automakers to meet the 1970 standards efficiently. Currently, automaker are lobbying against the government’s attempt to pass legislation that would tighten restrictions on automobile emissions. The automakers contend that these new restrictions would be overly expensive and unnecessary to efforts to curb air pollution. Clearly, the automobile industry’s position should not be heeded.

Which one of the following most accurately expresses the method used to counter the automakers' current position?
(A) The automakers’ premises are shown to lead to a contradiction.
(B) Facts are mentioned that show that the automakers are relying on false information.
(C) A flaw is pointed out in the reasoning used by the automakers to reach their conclusion.
(D) A comparison is drawn between the automakers’ current position and a position they held in the past.
(E) Evidence is provided that the new emissions legislation is both economically feasible and environmentally necessary.

正确答案为D.

我选了E, 原因是当时认为"automaker's position never changed", 所以D的
"comparison"不能推断出"automobile industry’s position should not be heeded"的结论. 唯一能推出此结论的是"Evidence with catalytic converter".

我最近刚开始准备考G,OG的语法和逻辑刚看完第一遍,LSAT做完了6个session, 每24题大概错4道,40分钟完成.自己感觉逻辑的思路还没有形成,尤其是Boldface题和这种"what's the method used"题.请前辈们指教!

在文中并没有你的假设，而且“把过去和现在等价，把现在和将来等价”是一个常见错误，原因就在于随着时间推移，变化是可能发生的。这个错误还经常出现在AWA的Argument中。另外，你可以从网上下载新东方的GMAT网络课堂。个人感觉，Argument对削弱题有帮助。
