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.
