@Almas,

For this question, look at the chain we've made from the rules.

From the rules, we know that

L---P---N

J---O---K---M

and P---O

Because P---O, we know that we can
combine these two chains to tell us that P---O---K---M.

We're trying to figure out how man variables can go in the top 3. We
have 7 variables in total. Looking at our chains, we see that there
are three variables—M, K, and O—all of which have at least 3 variables
ahead of them.

M has L, P, O, K, and J that all have to be ahead of it, so the
earliest it could go is in 6. However, we also know that N cannot go
last, so that means M must be 7th.

K has O, J, P, and L all before it, so the earliest K could go is 5th.

O has J, L, and P all before it, so the earliest it could go is 4th.

All of the other four variables—J, L, P, and N—do not have 3 or more
variables in front of them, which means all of them could potentially
go in one of the top three spots.

Hope this helps. Let us know if you have more questions!
