How many of the commercials are there any one of which could be aired last?

Why only 2

Why don’t the rules say that fs or sf come before P?

Hi @dalilapando, I think the final rule is giving us a relationship between F and S, and the only rule we have about P is that it is before G, which is the only rule about G. Sometimes there will be deductions that are not apparent from the rules immediately.
