You are walking down a road and you encounter a fork in the road and you do not know the correct way to go. There are two men standing at the junction and both know the correct road. One man always lies, and the other man always tells the truth, but you do not know who is the liar and who is the one who tells the truth. You can only ask each man one question, but it must be the same question for both. What is the question that would allow you to get the information necessary to choose the correct path?
Answer: You ask, "Which way would your companion say is the correct path?". The liar would lie tell you that the truthful man would say to go down the wrong path. The truthful man would tell the truth and say that the liar would tell you to go down the wrong path. They both point to the wrong path, so then the alternate is the proper path.

Answer: Step 1: Select any 6 marbles. Place 3 marbles on each side of the scale. If one side goes down, go to Step 3. If they balance go to Step 2.
Step 2: Place the two remaining marbles on the scale. The marble that goes down is the heavy marble.
Step 3: Using the 3 marbles that went down in Step 1, select any 2 marbles. Place one marble on each side. If one side goes down, that is the heavy marble. If they balance the other marble is the heavy marble.

In the basement there are 3 light switches in the off position. Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches, but you may only go up stairs one time. How can you determine which switch controls each light?
Answer: Turn any one switch to the "on" position for 5 minutes, then turn that switch "off". Quickly turn any other switch to the "on" position and run up stairs. Feel the two lights that are "off". One of them will be "hot" because is was "on" for 5 minutes. Obviously the "hot" bulb is controlled by the first switch you turned "on". The light that is currently "on" is controlled by the switch you last turn "on". The "cold" bulb that is "off" is controlled by the only switch left. When solving problems we often need to use all our senses.
