Asking questions is actually not described as part of the play loop in either 5e PHB. Both say the DM describes the scenario and the players describe what they want to do.That is NOT the 5E play loop. The 5E play loop is that the GM describes the scene, the players ask questions, the GM responds, and this continues until there is a point of uncertainty, at which time the GM decides how to resolve that uncertainty (usually calling for an ability check of some kind). The entire point is resolving the uncertainty. If a task cannot succeed or fail, there is no uncertainty and a roll is not called for.
If the GM calls for a roll in the situation, that means, by definition, that the roll must resolve some uncertainty either way. If the roll is a success -- based on the DC the GM set -- then the uncertainty should be resolved positively.
Granted, asking questions to clarify aspects of the description of the environment that might not have been clear is, I think, taken for granted by these descriptions of the gameplay loop. But I like that it isn’t explicitly stated to be part of the play loop, because asking questions doesn’t really move the gameplay forward. It actually stalls gameplay, because time spent asking and answering questions is time that no action is occurring in the fiction. This is why I try to encourage my players to declare actions with intent to reveal the information they want instead of asking questions. “I look for an exit” is better than “do I see any exits.”
