01 What is the most appropriate reason for using light preliminary lines?
Answer and explanation
Correct answer: D. They make corrections and proportion changes easier
Explanation: The governing concept is flexible construction in sketching. Light preliminary lines are drawn with low pencil pressure, so they can be erased, shifted, or redrawn while the artist checks proportion, placement, and alignment. Therefore option D is correct. Glossiness, permanent shading, and automatic texture do not result from faint construction marks; those depend on paper, value control, and surface observation.
