Uncertainity in the question (lookup lab)


In the lab, the question is vague, should air_routes be specified as a collection or not? IMO, yes.

Which lesson/quiz exactly?

We do not have access to the link you supplied as it points to your own personal instance of the course.

It asks for which alliance (which are documents in the air_alliances collection) flies the most routes (which are in air_routes collection). Also the lab is about Using $lookup, so you need 2 collections. Both are named in the question, air_alliances and air_routes.
