Picked B over A because it would provide more support for resolving the disparity if true over A. (Most AC use is from businesses vs. Not the only significant factor [conceding it's still significant])

Arg, got it right in the timed but wrong in the blind 🥲

Felt like cheating when answering this question because one of my profs works for the CDC, and we've talked about lead poisoning, and how it is caused by more than just lead paint.

whoopsie

I eliminated B because of the "build the bridge" approach we've learning (I thought since the AC started off with the conclusion it was wrong, so I immediately eliminated it 😔)

But I definitely see how B is clearly the best answer; just need to take a step back sometimes and not wholly rely on test-taking techniques.

Finally didn't make the backwards bridge mistake 🥲 i feel like a logic adolescent instead of a logic baby now 😎

Not sure if this is 100% good practice, but I have found myself eliminating answer choices that say "Whether or not" because it's grammatically incorrect (you just need to say "whether"), and so far, it has worked every time.

Has anyone else done this or can attest/deny this method?
