Choose all possible answers for this disjunctive question. All rules have been learned, haven't they?

The question is a tag question: 'All rules have been learned, haven't they?'

A tag question is a statement followed by a mini-question at the end. We use tag questions to confirm information or ask for agreement.

Since the statement is positive ('All rules have been learned'), we expect a negative tag ('haven't they?'). So, the positive answers would be best here.

• Yes, they have.
• Yes, they have been learned today.
