How do you answer a question someone asks you, when the question isn't true? The question takes for granted an answer that you haven't responded to and is really asking you a follow up question.
The famous complex question fallacy is "Have you stopped beating your wife, yet?" It is taken for granted that it is a known fact that you beat your wife.
Lawyer's trick. It's an unjustified presumption. It's a trick question.
Don't answer these types of questions. They are trying to incriminate you.
