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.

(A) does nothing to strengthen the claim. All others do

I vote for none of the above. I think all of them strengthen. However, I chose A as well b/c it was the weakest.

B: saves money OUT
C: accidents, less chance of fatal accidents OUT
D: def OUT saves lives
E: saves money OUT

A: If times are not lengthened considerable then there is less of a chance of an accident so I think this can somewhat strengthen the argument, it is weak though when compared to the others. So its it. Anyway care to elaborate more on this?
