I understand why Q can be the only one, but I cannot understand why S cannot. I am not seeing any sufficient conditions that must pair S with other representatives. Any help?

That's because of this rule, rwitt09:

"If Quijada does not present, then Pesek does."

I discussed the impact of this rule in the thread that explains the overall setup for this game, which is here:

viewtopic.php?f=1438&t=35543

Rules like this that have a negative sufficient condition and a positive necessary condition mean that every solution to the game requires at least one of those two variables. If S was the only variable in the game, then Q would not be present. But this rule means that if Q is not present, P is present, and thus S would not be alone! P could be alone, or Q could be alone, but nothing else could be thanks to that one rule.
