Yes, the person that wrote the question (not necessarily the OP) Is either brilliant, or a total idiot.

I still interpret it to scenario #2. Wherein movement means movement relative to an outside observer of the equation, i.e. someone standing on the ground off the treadmill and not in the plane.

Was that what the question asked? Hard to say. We all (or at least 99% of us) know that a plane will not take off if it does not move through the air. The jets or prop do not provide the lift, they only provide the forward momentum.
