At Google's headquarters in Mountain View, Calif., yesterday, three national teams competed in the finals of the National Geographic World Championship, the culmination of an international geography competition pitting countries against each other in world knowledge.
Legendary Jeopardy host Alex Trebek moderated the hour-long quiz show event that challenged students to identify world locations, languages, animals, and cultural artifacts.

Trebek was using crutches at the event because, as he explained in typical Jeopardy question-and-answer form, he had fallen down while chasing a burglar who'd stolen things from his hotel room in San Francisco.

Chinese Taipei had the lead going into round 5, but missteps late in the game quickly dropped them from the top spot.
