Help with A

Hi LSAT Max! I chose answer choice A because I thought it undermined the part of the stimulus that mentions smaller cars built after 1977 had a higher incident of car-accident related fatalities. Did I set myself up for failure by misreading that part of the stimulus and not focusing my attention to the conclusion talking about the opposition of recent guidelines to produce cars with higher fuel efficiency? Thank you in advance for the help!

@Julie-V,

Happy to help. Let's look at (A) and (C).

(A) says, "Even after 1977, large automobiles were frequently involved
in accidents that caused death or serious injury."

One of the argument's premises has already given us information that
small cars were involved in accidents at a greater frequency than
smaller cars, so having knowledge that large cars were frequently
involved in accidents doesn't give us any additional relevant
information. Thus, we can get rid of (A).

(C) says, "New computerized fuel systems can enable large cars to meet
fuel efficiency standards established by the recent guidelines."

If even large cars can be produced to be more efficient, then the
executive's conclusion does not make sense and is called into
question. Thus, (C) is the correct answer choice.

Does this make sense? Let us know if you have any other questions!
