When you blow some air above the upper face of a paper strip, the paper rises. This occurs because

A) the air above the upper face of the paper moves faster, which makes the pressure lower than at the lower face. B) the air above the upper face of the paper moves faster, which makes the pressure higher than at the lower face. C) the air above the upper face of the paper moves slower, which makes the pressure lower than at the lower face. D) the air above the upper face of the paper moves faster but the pressure remains constant. E) the air above the upper face of the paper moves slower, which makes the pressure higher than at the lower face.
