The global diagram:
Question 8 is a local must be false question. We are supplied the information that L is in 3.
With L being third, we can see on our global diagram that L has two variables that must precede it, so they must occupy those two slots in front of L. It must be in the order of M-S, so M will be 1 and S will be 2.
We now only have three variables left. We can see that there is an order to those three. V and Z must be prior to O. This means O must be last. The order of V and Z is not certain so I placed a flipper above them to indicate that these two variables can flip spots with no problem.
