Hi, for this question, we need to see the implications of the two Ls. We always know that the P committee is full, so we have the following setup for this question

P: f g h
Q L _ _
S: K L _

We know that every committee must have an officer, so the final spot in sales must be either f or h. This means that the only spot for M is in q, and since m must appear at least once, it must be in q.
