And why are we assuming that just because cars don't run, they still don't emit pollution?
I just can't understand how the company paying only scrap metal prices (wherever that came from) for "used" cars weakens the argument.
Thanks for posting
levyyun!
First, I'm not entirely sure how a car *could* emit significant air pollution if it wasn't running. The LSAT would consider it common knowledge to have some awareness that the vast majority, if not all, of the air pollution caused by cars comes from them burning fuel. That junker sitting up on blocks in your neighbor's yard isn't emitting any significant air pollution because
it isn't doing anything that would cause it. It's just sitting there.
Even if it were possible that some tiny weird amount of air pollution were wafting off of cars that don't even run, it would certainly be a tiny, tiny fraction of the overwhelming air pollution caused by cars
running. So, if the cars being purchased by the company are those that don't run, even if it somehow managed to reduce air pollution in that teeny, tiny, fractional way, it wouldn't be much at all, and it seems extraordinarily unlikely that this reduction would be
greater than the reduction from redesigning the plants.
We don't actually need to
equate "used" to "old" in order to process this argument.
(C) tells us that the vast majority of the cars sold to the company don't run. On a certain level, I don't really care
why this is true, just that it IS true. Don't get too caught up rationalizing why the scrap metal prices mean that most of the cars bought up don't run, or trying to argue with it. The answer choices TELLS YOU that the result is that most of the cars bought don't run - that's the critical piece of information you have to assess. If that's true, what impact does it have on our argument?
If most of the cars bought don't run, that means we are buying up mostly cars that aren't actually emitting much air pollution, and that means that our plan is not reducing air pollution much at all - this completely undermines our argument that this plan will be
better than redesigning the plants.
It also sounds like you are frustrated that the correct answer brought up a new, seemingly-out-of-nowhere idea (paying only scrap metal prices). But this is often true in correct Strengthen and Weaken answers! It's extremely common for an answer to introduce a new, seemingly out of scope idea that actually
has a significant impact on the likelihood of the conclusion.
Here, the scrap metal thing is mostly just a distractor - that's WHY we end up with only non-running cars being purchased, but the WHY doesn't really matter too much. The important part is just the idea that "most of the cars bought by the company weren't running anyway".
What do you think?
