**Formal part in Tag Questions:** 1. They are busy, **aren't they**? - Explanation: In the formal context of tag questions, when the main clause is affirmative, the tag is usually the opposite. Here, the main clause "They are busy" is affirmative, so the tag should be negative, making it "aren't they?" 2. You aren't ill, **are you**? - Explanation: In this case, the main clause "You aren't ill" is negative, so the tag should be positive. Therefore, the correct completion would be "are you?" 3. There is a cake on the table, **isn't there**? - Explanation: Since the main clause "There is a cake on the table" is affirmative, the tag should be negative. Thus, the correct tag question is "isn't there?" 4. She can't swim, **can she**? - Explanation: The main clause "She can't swim" is negative, so the tag should be positive, making it "can she?" 5. Your grandparents have got a nice garden, **haven't they**? - Explanation: Since the main clause is affirmative, the tag should be negative in this tag question. Therefore, "haven't they?" is the correct completion. 6. Your sister hasn't got a guinea pig, **has she**? - Explanation: The main clause here is negative, so the tag question should be positive. Hence, the correct ending is "has she?" 7. You don't wear jeans, **do you**? - Explanation: Since the main clause "You don't wear jeans" is negative, the tag question tag should be positive, resulting in "do you?" 8. They often write dictation, **don't they**? - Explanation: In the case of an affirmative main clause, the tag should be negative. Therefore, the suitable completion here is "don't they?" 9. Mike doesn't play tennis, **does he**? - Explanation: The main clause being negative, the tag question tag should be positive. Hence, the correct way to finish the sentence is "does he?" 10.
