Supply the missing premise that makes the conclusion follow logically: P: D–most–BP: ?C:B–some–C

Daily Drill

Hello, I am curious on how a MOST and SOME statement became an ALL statement. I thought the answer would be D- (sometimes) - C not D is C?

Hi JazaneElaine,

We are asked here to add in a missing premise- which will make the conclusion valid. So what is actually happening here is that a most and an all are becoming a some, rather than a most and a some becoming an all.

Hello can anyone explain what "most" and "some" even mean in the problem?

Hi, these are shorthands for statements like "most rainy days are cold" which we could diagram as

RD -most- cold.

I'm still not clear on how most becomes all since most lsat prep states you're only supposed to assume common knowledge and nothing else. Why are we asked to add a missing premise, and how do we know we were asked that?

This is specifically meant to mirror strengthen with sufficient premise questions (aka sufficient assumption) questions, and honestly, I think these drills really only make sense in the context of those questions
