understanding the stimulus

Hi LSAT Max, I think my brain just shut down midway through my reading of the stimulus. I don't know if it's because I wasn't grasping what the last two sentences were saying or maybe I misread the whole thing, but do you have any advice to tackle a stimulus where nothing gets absorbed and you don't know how to go about it? Thank you in advance!

@Julie-V,

If you've read it once and don't understand what's going on, I
recommend re-reading it.

In general, though, it's best to make sure that you're understanding
what's going on after each sentence you read. If you read the first
sentence and don't get it, re-read it. Answering the question
correctly will be extremely difficult if you don't know what's going
on in the stimulus.

Also, perhaps try slowing down a bit while you're reading so that you
can absorb what's in the stimulus more easily. Give yourself some time
to internalize and process what you're reading, and that should help.

Does this make sense?

Now, let's look at this question.

We're told that the Scorpio Miser costs more than the standard Scorpio
car, but it is more fuel-efficient. Right now, you would need to drive
the Miser 60,000 more miles to break even at that cost difference.
However, if fuel prices went down, you'd have to drive it fewer miles
to get to the break-even point.

Do you see the problem here?

If the fuel prices go down, then you aren't saving as much money as
compared to the less efficient standard Scorpio car. Thus, the
argument actually has things backward. If fuel prices were to go down,
you would actually have to drive more miles before getting to the
break-even point.

(C) says, "With the Roadmaker, a crew can repave a mile of decayed
road in less time than with the competing model, which is, however,
much less expensive. Reduced staffing levels made possible by the
Roadmaker eventually compensate for its higher price. Therefore, the
Roadmaker is especially advantageous where average wages are low"

If you do not have to pay workers as much, then it makes less sense to
buy the Roadmaker, since you will be saving less. However, the
argument in (C) actually states the opposite, which means it has the
same type of flaw as the one we found in the stimulus. Thus, (C) is
the correct answer choice.

Hope this helps. Let us know if you have any other questions!
