• ask questions, use the answers: usually this means you simply are asking to the players "what do you do?" and react with your moves to their answers, but it also comes in play when you ask something like "how's the architecture of the southern realms?" and here it's just the player that replies to you, the character has nothing to do about it.
That's not strictly the case - the GM is meant to address the character, not the player. So, really you're asking "what's the architecture of the Southron Realm?" of the character. The player can decide what the character knows and answers accordingly.
