In this argument the author jumps from saying that not voting limits the emotions of donors and then conclude that charitable organizations should let donors vote to raise funding by raising emotional levels. This argument seems to assume (among other possibilities) that having emotional reactions somehow leads to more donating. In any case, there is certainly a gap in the argument as it stands now.
Let’s see if any of the answer choice respond to this potential assumption or point out another one we might have failed to notice.
(A) is out of scope. The argument is not interested in the most effective way to give donors control of organization but rather the most effective way to get more donations.
(B) supports the conclusion, but it’s not an assumption of the argument. What "most" charities have done does not prove that this is fail proof. Moreover, this is reaching too deep as well _ we are looking for a necessary conclusion rather than a sufficient one (where most, though too much information, might factor into an answer nonetheless).
(C) confirms a premise, but not a premise that directly links us any better to the conclusion than it does already. We really need an assumption that links emotion rights or fundraising.
(D) would get us to the conclusion, but it is not what the author has in mind. We can see that because the author is putting forward based on emotions rather than based on what donors want for their money explicitly.
(E) is what we have been looking for the whole time _ a connection between donation money and emotions!
