Why does graphite become shiny when heavy pressure is repeatedly applied to dark values?

Answer and explanation

Correct answer: Graphite and paper grain become compressed and smooth

The governing concept is burnishing. Repeated heavy pressure pushes graphite into the paper fibres and compresses the paper tooth, producing a smooth, reflective surface that can look shiny. This is a surface change caused by pressure, not by a change in the light source or an eraser. The pencil does not turn white. Building darkness with several light layers preserves texture and reduces unwanted shine, so option C is correct.
