01 If a cube and a round fruit are placed together in a still life then what mainly expresses the difference in their volumes?
Answer and explanation
Correct answer: C. By different light and shade transitions according to their surfaces
Explanation: The governing concept is form-based shading: a cube has relatively clear planes, so light and dark change more abruptly, while a round fruit has a continuous curved surface and therefore shows gradual tonal transitions. Option C is correct because these surface-specific changes make volume visible. Identical outlines, colour names, or one flat tone cannot adequately describe three-dimensional form.
