Why may erasing become difficult after graphite has become shiny?

Answer and explanation

Correct answer: Excess pressure compresses the graphite and smooths the paper surface

Heavy pressure compresses graphite into the paper fibres and smooths the paper tooth. This burnished surface holds the graphite more firmly and leaves fewer irregular fibres for an eraser to grip, so lifting the mark becomes difficult. The problem is not excessive roughness, colourlessness, or a change in shadow direction. To preserve correction control, build dark values with several light layers instead of pressing hard at the beginning. Therefore, option D is correct.
