Tansen did not seem to understand his teacher. Did he?

In the given statement, the auxiliary verb 'did' in the main clause is used to frame the question tag.

Question Tag:

• The function of a question tag is to change a statement into a question.
• A negative statement or clause gets a positive question tag; while, a positive statement or clause gets a  negative question tag.
• A question tag is formed using the same auxiliary verb in the main clause or statement.
• A question tag is mostly used at the end of a statement to make the reader or listener agree to the statement.

Answer 2

Tansen did not seem to understand his teacher, did he? -This is the answer.

About question tags:

• Question tags are words that are added at the end of a sentence to change the statement into an interrogative statement.
• They form 'yes/ no' questions.
• If the sentence is in positive, the tag must be in negative ('not' must be added).
• If the sentence is in negative (if 'not' is used) , the tag must be in positive.
• Here the verb is in negative 'did not'.
• Thus the verb must be the same as used in the sentence, but in its positive form (did) in the tag.
• The person followed by the verb must be the subject used in the sentence. So it finishes with 'he'.
• Comma must be used before the question tag.
• Question mark must be added at the end compulsorily.
• Therefore the answer is: Tansen did not seem to understand his teacher, did he?
