Why can repeated erasing damage the paper surface?

Answer and explanation

Correct answer: Paper fibres may lift or wear away

The governing concept is the physical effect of friction. Repeated or forceful rubbing can abrade the paper fibres, roughen the surface, and remove sizing or surface particles. Later graphite may collect unevenly, producing patchy shading or shiny rubbed areas. Option A is correct. Graphite does not turn into metal, the sheet does not expand because of erasing, and the pencil’s hardness does not change in this way.
