About Self-Referential Quiz

These kind of puzzle was created by Jim Propp (professor of mathematics at the University of Massachusetts Lowell). The first test he created was named "Self-referential Aptitude Test" (SRAT) and it was created as some kind of joke because there is only 1 question of 20 that can be solved directly. The others questions make self-references to their own answers.
