Step-by-step explanation:
The subject of this question is English.
In English grammar, question tags are often used to confirm information. When making question tags, the main verb or an auxiliary verb is used. If there is no auxiliary verb, the question tag uses the main verb or 'do', 'does', or 'did'. If the question is positive, the question tag is negative, and if the question is negative, the question tag is positive.
For example, in the sentence 'You are a singer, aren't you?', the main verb 'are' is used in the question tag 'aren't you?'. In the sentence 'You lived in Lima, didn't you?', the main verb 'lived' is used in the question tag 'didn't you?'
