premise: The white-helmeted driver of the red, white and blue car, with a passenger riding shotgun, whipped up dust and rocks in the wooded taped-off area, the debris creating an eerie, ghostlike view of the face of the person behind him. hypothesis: There is a white-helmeted driver stopped at a stop sign.
contradiction: The driver cannot be in a car that whipped up dust while moving, and in a car that is stopped.
