We will respond to the question, which means ‘what is wrong,’ using the ～んです form to express our answer as an explanation.

The ～んです form, like は and が before it, can be somewhat hard to know when to use properly. Naturally, what is an explanation and what is a statement of fact can be subjective. You will very often hear this form used in casual (and formal) speech with sentences that do not obviously seem to be explanations. The better way to think about the ～んです form is to consider that it gives an air of explanation to a statement and less that it turns something into an explanation. In this way, the ～んです form can be combined with other phrases and sentence structures to express anything ranging from apology to explanation to deductions and so on.

As we learned in the textbook, you can use の instead of ん in ～んです constructions. This is more common in written Japanese, and it is more formal to use の than the abbreviated ん.
