That is the most horribly awkward question I have ever read. I hope you weren't graded for that. If you were, any teacher should give that to you if you argued your point [i.e. there have to be TWO forces, one to push and one to push back. Also, I don't understand why it can't be the friction answer]. If they don't, you can take satisfaction that he/she is a small person in a stupid world. In real college this kind of thing comes up sometimes, but there are always people that march down to the front of the room, shove it in the professor's face and say "what the fuck is this asking me?", and make him explain it to the class.
