Question

Which of the following is a clue that something has been erased on a document?

Answer 1

The fibers of the paper are disturbed when looked at under a microscope

Answer 2

I suppose this should have choices. Usually, a black felt pen would be used to cover some words and sentences. If an erasure has been used, a white ink has been used to cover some words. If a rubber erasure has been used, one will find bits of rubber around the paper and on the floor of the place where the paper was stored
