_____ and _____ are in Brooklyn

What does this mean. It asked what borough we live in and I said Brooklyn and I don't get what the 2nd question is

In the statement "_____ and _____ are in Brooklyn," the phrase "What borough do you live in?" is not a question being asked in the statement itself. It seems like someone is asking you a separate question about what borough you live in, with Brooklyn being one possible answer.

To properly respond to the question about what borough you live in, you can simply state "Brooklyn."
