Quiz Answer Key and Fun Facts

2. If all snarks are sneels, and some sneels are bontos, then some snarks are definitely bontos.
3. If you are about to have drinks with someone, and they tell you that they poisoned one of the glasses, but that you can choose which one you want to drink (yours or theirs), you can definitely use logic and your knowledge of the other person to determine which cup is poisoned.
4. You are in a prison with 99 other condemned men (100 total) who are going to be executed the next morning. The warden decides to give all of you a fighting chance though. You are told this:
You will all be put in line, facing forward, so that you can see everyone in front of you, but no one behind you. The warden will put either a white hat or a black hat on all 100 people, and then each person will try to guess the color of the hat he is wearing. If the person can guess the color of his hat, he gets to go free. (You can only say "black" or "white". Saying anything else will lead to everyone being shot.) The warden will start at the back of the line (the person who can see everyone else's hat) and work his way down to the front (the person who can see no one's hat). There is no set number of hats. The warden could put a white hat on everyone, a black hat on everyone, or anything in between.
That night you and the other condemned men try to come up with a plan that will save the most people. You come up with the best plan possible that guarantees that you can save ____ people.
5. There are three logicians having a rational and cogent debate over who is the most logical. A mediator says, "I have 3 white hats and 2 black hats. I will put a hat on each one of your heads, so that you can see what color hat the other two people have on, but you cannot see your own hat. Whoever can tell me what color hat they have on first is the most logical." He puts a white hat on each of their heads.
Is it possible for one of the logicians to logically determine what color hat he has on?
6. You're in a room with two doorways, A and B, each guarded by a guard. One of the rooms leads to fame, fortune, and happiness. The other one leads to a torturous death. You do not know which door is which. You are allowed to ask one of the guards one question. The catch is, one of the guards always tells the truth and the other one always lies, but you don't know who is who.
There is no single question you can ask that will enable you to logically determine which door leads to fame, fortune, and happiness.
7. You are in the land of Logica, where there are three types of elves. Blue elves always tell the truth, green elves sometimes tell the truth, and red elves never tell the truth. The problem is, you are colorblind, and all the elves appear gray. You walk up to an elf and the elf says to you, "I always lie." What color elf are you speaking to?
8. "Even though the bar at which the man the woman likes is is closing, the man badgers Moose resident Cat to let him stay the night."
