Answer 1

A few students wrote the answer, didn't they ?

Answer 2

A few students wrote the answer, Didn't they?

Explanation:

• Question tags are words or phrases that are asked as a confirmation of the statement that is made.
• Question tags usually contain two words, one is the participle, questioning the verb mentioned in the sentence and the other is a pronoun used to address the subject.
• One of the basic rules of question tags is if the sentence given is positive the question tag is supposed to be negative and vice-versa.
• As the statement here is an affirmatory sentence, the question tag used has to be a negative one Didn't they?
• They in this tag refers to the students who wrote the answer.
