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.

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.

Straight D ...
just because the automobile industry failed to predict the feasibility of act's standard for emission in past , it does not mean that this time also they are wrong . ...

Simplify the argument -

Automobile Industry
1970
New Standards --> 1. Not necessary 2. Not economically viable.

However,
Catalytic Converters --> Made following standards economically viable.

Now
New Standards --> 1. Not necessary 2. Not economically viable.

Author
Do not heed the automobile industry's claims.

Why does the author say so? He thinks that a new technology (something like catalytic converters in 70s) will be invented that negates the claims of the automobile industry.

Which option closely says so? Option D.

Option A - Incorrect.
they do not lead to a contradiction. Contradiction implies two opposing conclusions. Nothing like that here.

Option B - Incorrect.
Nowhere is it mentioned that automakers' information is false.

Option C - Incorrect.
No flaw is pointed out. The author directly makes a conclusion based on historical evidence. It is not necessary to assume that what happened in the past must repeat now. Hence, no flaw.

Option E - Incorrect.
No such evidence is provided. The author directly gives a conclusion that the automobile industry's claims must not be heeded to.

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. X
No contradiction present.

(B) Facts are mentioned that show that the automakers are relying on false information. X
Did not happen.

(C) A flaw is pointed out in the reasoning used by the automakers to reach their conclusion. X
This is true of the automaker's previous conclusion, not their current one.

(D) A comparison is drawn between the automakers’ current position and a position they held in the past. CORRECT
-so the key focus here is we are trying to counter the automaker's CURRENT position. The author does so by using the past as a precedent and concludes that the automakers are full of blasphemy.

(E) Evidence is provided that the new emissions legislation is both economically feasible and environmentally necessary. X
