@meepmeep your comment was posted a while ago, so i'm not sure if this will be much help as of now, but what works for me is identifying the conclusion before looking at the answer choices. if the excerpt in the stimulus is NOT the conclusion, i can immediately eliminate the choices that say it is the conclusion.

it's so frustrating choosing the wrong answer bc when i review it and read the explanations, i go "ohhhh" and realize the question wasn't so hard at all
