What is the likely reason if soft-pencil marks do not adhere over shiny graphite?

Answer and explanation

Correct answer: The surface has become overly smooth from compression

The governing concept is loss of surface tooth through compression or burnishing. Heavy earlier pressure can polish the graphite and flatten the paper texture, leaving few irregularities for a fresh soft-pencil layer to grip. Thus option D gives the material reason for poor adhesion. Pencil length, paper colour, and a change in light direction do not normally prevent graphite from adhering to the surface. Darken gradually before the surface becomes glossy.
