LSAT 82, Logic Game 4, Question 21, LSATHacks

This question asks what happens if W presents on two subjects. Now, you could sit here staring at the question and “think” about what can happen.

This tends to be unproductive though. On logic games, thinking happens by drawing, not in your head. For this game, there are only three presentations. So, if W does two presentations, that means she is in two out of three groups.

There are only two ways to place W twice and two scenarios are easy to work with. So, draw them and see what happens:

(If W is in M, they’re also in S. That’s why there’s no third scenario with W only in J and M)

I drew that R can’t go in M or S. Why? Because rule 3 says everything in M must go in S. And rule 2 says R and W can’t go together in S. So, if we did place R in M, we’d also have to place R in S, with W.

So, R can’t go in M or S. But, we have to place R somewhere. So, J is the only place they can go:

When you make a major deduction like that, you should check if it solves the question. It does in this case: D is CORRECT. R has to present on jitsuaku.
