SELF-REFERENTIAL APTITUDE TEST, by James Propp (jamespropp at gmaildotcom) The solution to the following puzzle is unique; in some cases the knowledge that the solution is unique may actually give you a short-cut to finding the answer to a particular question. (Thanks to Andy Latto for bringing this subtlety to my attention.) I should mention that if you don't agree with me about the answer to #20, you will get a different solution to the puzzle than the one I had in mind. But I should also mention that if you don't agree with me about the answer to #20, you are just plain wrong. :-) You may now begin work. 1.
