Resolves YES if someone can find me an example before close, and NO otherwise. It must have resolved before this market was created. 

To count as a "Will this market close at X%?" market, the resolution criteria for the market must be solely based on what probability it closes at, and the range of values which would qualify for a YES resolution must be at most 1% wide. So, for example, "Will this market close at 42%?" or "Will this market close at 0.1%?" would count, regardless of whether they were based on the displayed/rounded or exact percentage, but "Will this market close at a prime number?" or "Will this market close at 40 to 50%?" would not. If the market asked, "Will this market close at <=1%?", then it would not count if it was based on the rounded percentage (since then anything from 0 to 1.05% would cause a YES resolution), but it would count if it was based on the exact percentage (since then the range is 0 to 1%).

Also, the range of values that give a YES resolution must be a single interval, so no funny business like, "Will this market close at a rational percentage?" (which would otherwise work, since the rationals have zero Lebesgue measure).
