LSAT 84, Logic Game 2, Question 9, LSATHacks

This question places x last. We already know H is the architect that goes last, so that means H and x are together:

Next, you should consider the in/out rules. Since H has x, that means H doesn’t have y. I’ve underlined which parts of the diagram that triggers:

Since H doesn’t have y, F has w, and therefore L has z. (Since F doesn’t have z).

We can draw these two new deductions by the diagram:

In the setup, I showed how there were only two possible orderings: FGL, or LFG. That’s because FG have to be a block. Like this:

You can add in the deductions from this question: Hx, Fw, and Lz. G and y are the only ones left, so they must go together too:

This lets us solve the question. B is CORRECT. W can’t go third, because F can’t go third. Every other answer is possible.
