The questions typically have no straight forward answer, but require a level of reasoning or logic behind them that reflects the wisdom of the hopeful entrant to the tower. The knocker often compliments successful entrants for their skilful logic, but tends to go quiet if the answer is wrong. The question will remain the same until it is answered. The knocker will not let anyone in who does not know the answer to its question, though if someone else answers the question, one may enter with the help of another who answers correctly.
