EXPLANATION:

• Question tag is converts a statement into a question. They are usually used for confirming information which we think we discern is true. Generally, there are two main rules for question tags.
• Rule 1 is if the main clause/statement is positive, the question tag is usually negative for instance It's a been a splendid evening, isn't it, and if the main clause/statement is negative, the question tag is positive for instance, Don’t you like travelling, do you?.
• Rule 2, is the tense of the question tag is ascertained by the tense of the modal/auxiliary verb of the main clause/statement which precedes it. If the statement/main clause does not use a modal/auxiliary or it is in the present/past simple tense) then the auxiliary to do should be used. In the above case, the statement is positive, hence the question tag is negative.
