Question Tags Questions
The rules for using question tags in superlative sentences are as follows:
1. If the superlative sentence is positive, the question tag is usually negative. For example: "She is the smartest in the class, isn't she?"
2. If the superlative sentence is negative, the question tag is usually positive. For example: "He is not the tallest person here, is he?"
3. The question tag should match the subject of the sentence. For example: "You are the fastest runner, aren't you?"
4. If the superlative sentence includes "the only," the question tag is usually positive. For example: "She is the only one who knows the answer, isn't she?"
5. If the superlative sentence includes "the first," the question tag is usually negative. For example: "He is the first to arrive, isn't he?"
