What is the main benefit of starting with a hard pencil and progressing to a softer pencil?

Correct answer: Controlled dark values develop from a light base

Hard pencils generally make lighter, more controlled marks, so they are useful for establishing a pale base and early value structure. Softer pencils can then be introduced gradually to deepen selected areas and create stronger darks. This sequence gives better control over the tonal range and reduces the risk of filling or burnishing the paper too soon. It does not erase texture, thicken contours automatically, or lengthen only the shadow. Option A is correct.
