    1. Burning Ropes

      You are given two ropes and a lighter. Each of the two ropes has the following property: if you light one end of the rope, it will take exactly one hour to burn to the other end. It doesn't necessarily burn at a uniform rate. How can you measure a period of 45 minutes?

    1. Brown Eyes and Red Eyes

      There is an island of monks where everyone has either brown eyes or red eyes. Monks who have red eyes are cursed, and are supposed to commit suicide at midnight. However, no one ever talks about what color eyes they have, because the monks have a vow of silence. Thus, no one knows their own eye color; they can only see the eye colors of other people, and not mention them. Every day, the monks enjoy a silent brunch together at a round table. One day, a tourist visits the island monastery, and, unaware that he's not supposed to talk about eyes, says "At least one of you has red eyes." Having acquired this new information, something dramatic happens among the monks. What happens?

      Correct! 
      Wrong! 

      Okay, seriously?!? At this point, you should've figured out that I'm not giving away answers.

      Correct!
