Answer 2

We can add question tag like this-

They live in London, don't they?

Explanation:

Question tag -

It is a question which is added by the speaker to give emphasis on the important points.

Question tag is added at the end of the statement with the help of auxiliary verbs.

If sentence is positive then we have to add negative question tag and if the sentence is negative we should add positive question tag.

If helping verb is not available in the given sentence we should use 'do, does, did.'

The given sentence is in simple present tense so we should use 'do' to add question tag.

We should write the sentence as it is and then give comma.

After comma we should use don't and then proper pronoun.

Use question mark at the end.
