I answered C on this as well, and when I did it, I had reservations. The explanations are great, but here is what happened when I was reviewing it, and it cleared the way.
The question asked for which would help resolve the discrepancy EXCEPT.
A- Can be construed and seen as a valid reason to explain the paradox of why, if antilock brakes where safer, why are there more accidents. Because this answer is much like the answer discovered in real life when the seat belt laws came in to effect. Because people felt safer, they drove faster, and created a greater risk for themselves and others than the protection of the seat belt provided, so the increased speed was an unintended side effect of the seat belt. So something that was suppose to help, was going to help IF EVERYTHING ELSE STAYED THE SAME. Here, people drive MORE CARELESS.
B- The brakes DON'T WORK, whether it is real or imagined in irrelevant here. We take the statements at face value. They break down more often, that is a valid reason...Right or wrong in real life does not matter.
C- This is an UNSPOKEN two step ASSUMPTION if you will, or implied ...IT DOES NOT MAKE IT RIGHT OR WRONG IN REALITY....remember...the question ONLY asked for WOULD HELP..explain an APPARENT .... WOULD HELP...HELP HELP. Even if the contribution is TINY TINY TINY.... If the breaks are hard to repair, then ....assumed they would not be done as often or could be done wrong...etc. etc. etc. ... frail at best....but it can HELP... This is like SPOTTING someone at the gym...THEY push up 300 lbs....and you spot them with 2 fingers....technically..... you are helping.
D- Again....2 steps...they don't know how to use it...so they use it wrong....that creates a problem...and accidents occur that would not have happened, if they had had the regular breaks. They swoop when they should have sweared.....
E- I got here, and MISTAKEN repeated my original MISTAKE and was looking for something to close the gap...and could not get this to fit....and in a burst of rage and frustration....cursed the LSAT authors asking...."WHAT THE BLEEEEEP...DOES .....WORSE accidents have to do with MORE ACCIDENTS.......that is IRRELEVANT... and then I realized...in embarrassed silence.......ops. That was the purpose.
It not hurt the case, and it does not HELP the case....remember this questions that ask about HELP ...EXCEPT... can be any number of things..... Remember if it's worth TWO FINGERS it helps. Even standing next to someone shouting words helps...no contact at all but in some way we can't SEE it helps. Same here. It did not have to fill the gap....just two fingers, a kind word
