Questions 85-86

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, automakers 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.

85. 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.

86. Which one of the following, if true, lends the most support to the automakers’ current position?

A.        The more stringent the legislation restricting emission becomes, the more difficult it becomes for automakers to provide the required technology economically.

B.        Emissions-restriction technology can often be engineered so as to avoid reducing the efficiency with which an automobile uses fuel.

C.        Not every new piece of legislation restricting emission requires new automotive technology in order for automakers to comply with it.

D.       The more automobiles there are on the road, the more stringent emission restrictions must be to prevent increased overall air pollution.

E.        Unless forced to do so by the government, automakers rarely make changes in automotive technology that is not related to profitability.

这两道题完全不懂， 请大侠解释！多谢！

本家小刚，答案是什么啊？我选d a

首先，说上一次制造商阻挠法案，就是无中生有，没有的事，所以这次肯定也是， 所以是类比。

第二， 证明车商这次是真的，表明环保要求越高，在经济上月难以实现，这也是常识嘛。
