Mr. Dunnington tells us that this quiz was taken from the Readers Digest for July 1988. In the form that he sent it, the questions and answers were quoted verbatim; with true editorial timidity, I changed the wording rather drastically, in order to minimize the danger of copyright violations. The principle remains intact.
The quiz itself goes in a pretty straightforward manner: you get the question, and choose an answer. The computer then tells you whether you have the right answer, to the accompaniment of some rather clever SOUND (Line 2010) for a wrong answer, or a happy series of BEEPs (Line 2030) for the correct one.
