Doesn’t trigger the rule. The guidelines in the stimulus only apply to constructing new hotels. So we have no support for reaching any conclusions about what should be done in hotels that aren’t being newly constructed.

It’s a luxury hotel, so we can conclude we should include heating. And it’s somewhere that has high humidity throughout the whole year, meaning there’s high humidity in the summer, so we can conclude we should not include cooling.

Doesn’t trigger the rule. We can conclude a hotel should not have a cooling system if either (1) it doesn’t have a heating system or (2) it’s somewhere with high humidity in the summer. (C) doesn’t satisfy either of those conditions, so we can’t reach this conclusion.

Wrong conclusion. We can only conclude when a hotel should have a heating system—not when it shouldn’t have a heating system. In fact, the conclusion here is anti-supported, because we know luxury hotels should always include a heating system.

Wrong conclusion. We can only conclude when a hotel shouldn’t have a cooling system—not when it should. The absence of high humidity in the summer is necessary, not sufficient, for including a cooling system. So knowing that the hotel is somewhere with low humidity doesn’t tell us whether to include cooling.
