then why is Question 4 necessary and not sufficient?

This questions became so much harder for me because of the inclusion of "unlike today," in AC: E. Without that part it would such an easy choice. The correct answer choice trying to trick you into thinking that by being "existent" might mean that it's adequate therefore contradicting the stimulus. I had to make the inference that just because it's "existent" in comparison to 10 years ago it could still be a very small amount.

I eliminated A because the stimulus says nothing about how they sampled the 20 advisors. It could be that they are all from the same financial firm so it wouldn't be representative of all advisors.

Yeah i've been noticing that the mapping is actually making me waste so much time, and after mapping it out it doesn't even get me that much closer to the answer only confuses me further. In this question the first two are easily crossed out, same with E. You're left with C and D, you can cross out C because in never states that George squandering the money is going to harm him. I genuinely think the map would've messed me up, but it's most likely because I'm uncomfortable using it.

yeah that's exactly correct

A has a focus on the number of overall fruits produced while the stimulus is only talking about how many fruit are saved from insects. So it's a answer choice that is basically completely irrelevant in regards to the stimulus.
