Hello everybody, I recently took a drill and noticed that I got one of the answers incorrect because I didn’t know what one of the words meant. I usually don’t have this issue since 98% of the time I’m keeping up with the LSAT’s diction. I don’t want this mistake to happen again so I’m reaching out to anyone who is aware of a list of LSAT vocab that can reduce the odds of this happening again. If anyone could aid me it would be greatly appreciated. Thanks.

I am struggling to figure out as to why A is the correct answer.
