01 Where is the shadow side of a sphere?
Answer and explanation
Correct answer: B. Away from the light
Explanation: The governing concept is light-and-shade modelling of a three-dimensional form. When light falls on a sphere from one direction, the surface facing away from that source receives less direct illumination and becomes the shadow side. Therefore, option B is correct. The light-facing area is normally brighter and may contain a highlight, while the opposite turning surface contains darker values. A cast shadow may also fall onto the ground, but it is different from the shadow side on the sphere itself. The title and the area outside the paper have no relation to the object’s lighting. Always establish the light direction before placing highlights and shadows.
