nswerts to Question 3, 5, 6

My global diagram:



Question 3, as you can see, is a local question that tells us that M is third. We now know that G must be fourth since we were told that G was either 3 or 4.

We are asked for the soonest placement of P. With M being third, we can see on our global diagram that two variables must precede M, and in this order: F - L



We have only two variables left to place: P and H. The only rule governing the use of H is that it is to follow M, which it will do in either slot 5 or 6. So in regards to this question, we can place P 5th, which is the soonest we could do so with M third. Answer choice (D).

Question 5 is a global question asking us for a variable that could be placed in any slot. We know for sure that our floater, P, is one of those. Our answer is (E).

Question 6 is a local question that supplies us with a block of LM and asks us what could be true.

In this situation, I would frame what happens with G third and what happens with G fourth.



In the G3 example, the only place I can put LM is 4-5 so I can leave room for H.

In the G4 example, the only place I can put LM is 2-3 so I can leave room for F.



In the G3 example, only two variables are left: F and P. They can trade off in slots 1 and 2.

In the G4 example, only two variables are left: H and P. They can trade off in slots 5 and 6.

(A) is the only one that can be true. H could be 5th in the G4 example.
