3 The children are watching TV at the moment, ......?

The correct question tag is: ... aren't they? **Explanation:** The main clause is "The children are watching TV at the moment." Since the verb is in the affirmative form ("are watching"), the question tag needs to be in the negative form. The subject is "the children," which is a plural noun. Therefore, the corresponding pronoun is "they." So, the correct question tag is "aren't they?" Complete sentence: The children are watching TV at the moment, aren't they?
