If a value scale has no middle values what effect will it have on shading?

Correct answer: The transition from light to shadow will appear harsh and abrupt

The correct answer is A. A value scale arranges tones from light to dark. Middle values are the intermediate steps between a highlight or light area and a deep shadow. When these steps are missing, the eye moves directly from light to dark, producing a sharp, abrupt transition. This may be useful for a deliberately graphic or strongly contrasted style, but it will not produce a smooth rounded appearance. A is correct because gradual shading needs intermediate tones. B is wrong because softness requires more middle values, not fewer. C is wrong because value describes lightness and darkness, not hue or colour family. D is wrong because realistic texture depends on marks, surface cues, and light response, not simply on removing middle values. Memory cue: no middle tones means no smooth bridge.
