Explanation: Inverted third conditional. When omitting "if," the auxiliary verb "had" moves to the front of the sentence ( Had I known = If I had known ).
Explanation: "Unless" means "if not." The phrase already implies a negative meaning ( if we don't take ), so a positive verb in the Present Simple is required.
