Three thousand blank papers for undergraduate research can prove to be false. Undergraduate research requires four years of college to get a certificate, and cheating is not allowed. Moreover, every graduate's diploma, degree certificate and other important documents will be filed in the education department, and there are very strict procedures for issuing them, which are essentially different from the certificates that can be obtained by 3,000 blank papers, and can only be a piece of waste paper. Therefore, 3000 blank papers can prove that the certificate is false.
