The tiebreaker was impossible, though. It was basically "how much gold has been produced in the world in history," and "given that a troy ounce of gold is $1600, what is the current value of all that gold." I just checked wikipedia, and the question was taken from one paragraph in that.
-WikipediaAt the end of 2009, it was estimated that all the gold ever mined totaled 165,000 tonnes. This can be represented by a cube with an edge length of about 20.28 meters. At $1,600 per ounce, 165,000 tons of gold would have a value of $8.8 trillion.
