OK, it's a bit underspecified 😄

Say the opponent/challenger also gives a full list of answers to both sets of 1000 questions - but only for 2 or 3 minutes, after which you lose access.

Given that, what protocol could you devise that would convince him that you basically already knew all 1000 answers for 1 of the 2? But not revealing which?
