GMAT Critical Reasoning (CR) | Re: Recently, the tuition at most elite private colleges has been rising f

Why E is the correct answer in this question

I f there are grants and scholarships for
lower-incomestudents, then perhaps they can
afford to attend the EPCs — this hurts the
argument's conclusion. I f there are not grants
and scholarships for thesestudents, then the
argument's conclusion is more likely to be
true: these students won't be able to afford
these colleges .The “two paths" on this answer
do lead to strengthening the conclusion on one
hand and weakening it on the other.
