Since the 55-mile-per-hour speed limit was mandated on our highways

Question

Since the 55-mile-per-hour speed limit was mandated on our highways, both money and human lives have been saved.

All of the following, if true, would strengthen the claim above EXCEPT:

(A) Most highway users find that travel times are not appreciably lengthened by the 55-mile-per-hour speed limit.
(B) Highway driving at 55 miles per hour or less is more fuel-efficient than high-speed driving.
(C) Nearly all highway safety experts agree that more accidents occur at speeds over 55 miles per hour than at lower speeds.
(D) The percentage of fatalities occurring in highway accidents at speeds greater than 55 miles per hour is higher than that for low-speed accidents.
(E) Automobiles last longer and require fewer repairs when driven at consistently lower speeds.

My guess is (A), since all other options back up the claim that the new speed limit saves money and human lives, whereas (A) speaks about time-saving.

Although the time saved could be an additional advantage, it isn’t pertinent to the conclusion.

Here the conclusion that we have to strengthen talks about saving money and human lives, so any option which does not support either of these is our answer. 
A -  CORRECT ; it talks about time-saving which is not mentioned as part of the conclusion
B -  STRENGTHENS ; fuel-saving, hence money being saved
C -  STRENGTHENS ; human lives are being saved
D -  STRENGTHENS ; percentage of fatalities are high
E -  STRENGTHENS ; money-saving

only option A is not supporting the statement

Atharva_7 · Answer

All of them strengthen, Except.. which means 4 options will strengthen and 1 might weaken or be irrelevant. Option A is irrelevant, hence the answer.

Dbrunik · Answer

Got this question right, but i feel as though you could make a case that A would strengthen the claim since, well, time is money!

rebuke please?

As per my experience, this question is not aligned with GMAC format. However, the answer is A because only this option is talking time, which is not a strengthener and neither supports the argument well.

Abhiswarup · Answer

Statement A weakens the argument as all other statements either save money or increase safety

SKaur3 · Answer

Hi  Abhiswarup  
I don't think A is weakener.
It says

i.e. Highway users are comfortable and okay about this speed mandate.

But it doesn't directly support the conclusion that either money or human lives are saved that's why it is the relevant Answer choice.
