@kim,

Happy to help. Let's take a look.

On our board, we know M is 7th

_ _ _ _ _ _ M

We also have a big chain

L - P - N

J - O - K

P - O - K

We're looking to make a list of all of the pieces that could go in 1, 2, or 3.

We know M can't go there since it's 7th. Let's look at the other pieces.

Could J? Sure, it's got nothing before it.

Could O? No, as it has J, P, and L leading it. So O needs at least 3
spots before it.

Can K? No, as it's later than O.

What about L? Yes, as it has nothing before it.

P? Yes, as it only has L before it, so it could be in 2 or 3.

N? Yes, N could be in 3, as it only has 2 things before it.

J, L, N, and P could all go in the first three slots, so there are 4
pieces that could go in these slots. Thus, (C) is the correct answer
choice.

Does this make sense? Let us know if you have any more questions!
