How do you use question tags to seek information?

To use question tags to seek information, you add a short question at the end of a statement to confirm or clarify what you have said. The question tag should have the opposite form of the statement, with a positive statement followed by a negative question tag, or vice versa. For example, if the statement is "You like coffee, don't you?", the question tag seeks confirmation or clarification by asking "don't you?"
