-나요 is a question that opens the door only a crack. Open it at a shop front and you get 문 열었나요; open it with your notebook out and you get 해야 하나요; open it across from a patient and you get 열이 나나요. Open it with your hand resting on a document and it asks permission; open it through a restaurant doorway and it asks for a seat. Either way, it clears a space for the answer before the answer arrives.
