What happens if the hand moves closer to and farther from the eye during pencil measurement?

Answer and explanation

Correct answer: The measurement scale will become inconsistent

The governing concept is consistent visual measurement. A pencil measure is meaningful only when the eye, hand and pencil remain at a fixed relative position. If the hand moves nearer to or farther from the eye, the pencil’s apparent length changes because of perspective, so repeated comparisons use different scales and the object’s proportions become unreliable. Therefore option C is correct; colour, texture and light direction are properties of the scene, not effects of hand distance.
