                              @CheckItProblems Do we think it's fair to have nonsense combinations of mathy words/properties in these constructions? I think the point is to be able to discern the structure of the sentence regardless of the specific meaning of the mathematical jargon...

                            So now the prompt is more honest about the silly combinations of jargon.

                      Decided not to make students do full truth tables this semester.

            Please tell me it's perfect; I worked too long on it for it not to be.

        It was fun to think of a lot of naïve set theory theorems for students to prove directly and indirectly.

      Hmm. This is probably three separate quizzes, isn't it? I could use the same randomized set theory lemmas, but each quiz asks for a different style of proof.
