to benefit constituents, legislators need to think about the consequences.

currently, legislatures do NOT benefit constituents. Valid inference: therefore, they must not think about the consequences.

Task: WHY do they not?

I chose D at first and A in blind review bc I gaslit myself, but A doesn't actually explain anything about not considering the consequences--it just restates that legislation doesn't benefit people. D actually gives a cause and effect, even though the wording is a bit imprecise, which tripped me up.

I feel like for #5 part of the sufficient condition should be being in the US. First, it is specified; second, common sense supports that some countries have different ages. I did 21 & US -> A, which basically worked, but I was still surprised to see the explanation say "or older" was the conjunction.
