Watson keeps on rollin', rollin', rollin'

 The final scores have Watson leading with $35,734, followed by Rutter with $10,400 and Jennings in third with $4,800. While Watson has a vast database of trivia knowledge, it isn’t flawless. Today’s “Final Jeopardy!” category was U.S. Cities. Both Rutter and Jennings correctly identified Chicago as the city with the largest airport named for a World War II hero and its second largest for a World War II battle. Watson responded with Toronto. In tomorrow’s final match, Rutter and Jennings will compete against Watson in a full game of “Jeopardy!” The player with the highest combined two-day total will be crowned champion and take home the $1 million grand prize.
