01 What is the main reason for keeping the light family and shadow family distinct in pencil drawing?
Answer and explanation
Correct answer: D. To clarify solidity of form and direction of light
Explanation: The governing concept is grouping values into a light family and a shadow family. Keeping these groups distinct gives the viewer a clear reading of the object’s planes, volume, and light direction. Reflected light may appear inside the shadow family but should not usually become brighter than the light family. Therefore option D is correct. Paper texture, straight lines, and removal of local colour are not the main purposes of this grouping.
