Quiz Answer Key and Fun Facts
1. There is a barber in a small town in Italy. He shaves all and only those persons who do not shave themselves. Who shaves the barber?
2. Melissa's baby goes missing. Melissa finds that an alligator has taken the child. Melissa asks the alligator to give the child back. The alligator tells her that he will return the child if she answers a question correctly, but he will eat the child if she answers incorrectly. His question is thus: Will I eat your baby? Melissa replies, "Yes." What will the alligator do?
3. A teacher tells his students that there will be an exam sometime the following week, but the day on which it occurs will be a surprise. A student reasons that the exam cannot be Friday and be considered a surprise because the class will know that if it had not happened Monday-Thursday that it would indeed occur on Friday. He then rationalizes that it cannot be held on Thursday because he already reasoned it cannot be on Friday, and likewise if it had not occurred Monday-Wednesday, it would have to have been on Thursday. Consequently, he reasons the same for Wednesday, Tuesday, and Monday, thus coming to the conclusions that the exam will not occur because it cannot be a surprise. Can a surprise exam occur the following week?
4. This statement is false. Is this statement true?
5. I have in my hand a white handkerchief. I have in my other hand a black raven. I propose that I can prove that all ravens are black using my white handkerchief. Ravens are part of the category "Black items" Therefore all non-ravens are in a category "Non-black." My white handkerchief is a non-black item. Therefore this supports that all ravens are black. Does this logic support the idea that all ravens are black?
