What mainly causes shiny slick patches in a dark pencil area?

Answer and explanation

Correct answer: Excessive pressure burnishing the graphite

The governing concept is burnishing, in which strong pressure presses graphite particles into the paper and smooths the surface. The compressed graphite reflects light, creating a shiny slick patch even when the area is dark. Option A is correct because excessive pressure causes this effect. Very light pressure usually builds a lighter tone, while viewing distance and not using an eraser do not by themselves create graphite shine.
