If you ever find yourself on the “Jeopardy” stage in front of Alex Trebek and you’re totally stumped, what’s your best Hail Mary guess?

Well, someone has gone through every Jeopardy episode between 1984 and 2012, He looked at close to 200,000 clues and found that one has been the answer, or question in this case, 216 times.

The answer is, “What is China?”

Based on this analysis: You’d be wise to “focus on science, literature, history, and geography.” And the most common final Jeopardy category, at least recently, is “word origins.”
