I don't think we should do students' homework for them. Queries in the form of, "My professor assigned me to answer this question; please give me the answer" are an invitation to help a student cheat. I choose to decline such invitations.

If the information required isn't in the Wikipedia, then by all means let's respond to the query by adding that information. I'd love to know more about ocean currents, myself.

There's been discussion (last year, was it?) about how Wikipedia is like a library, or perhaps not like one. The reference librarian is happy to help you FIND YOUR OWN ANSWERS, thus facilitating your homework -- not doing it for you.

The point is to help you learn, to let you know.
