Light-Sport Aircraft Yahoo group Question for all Pilots

I had a discussion last week with Rich Stowell, an industry expert on stalls, spins, and unusual attitude recovery. He posed a very simple, fundamental question to myself and a student, and stated that 90% of pilots get the answer wrong. I'm curious how everyone on this group will answer.

What is the primary control surface used to turn and airplane?

I'd love to hear your answers. If you have time, click on this link to answer/discuss further:

Once we get some responses, I'll post a link to his answer.
