Those odds shrank considerably, however, when the final clue was actually revealed: "These two mayors gave their names to a facility built on the site of an old racetrack owned by Coca-Cola magnate Asa Candler."
To get that one, it helps to be familiar with Atlanta.
The mayors are former Atlanta mayors William Hartsfield and Maynard Jackson, and the "facility built on the site of an old racetrack owned by Coca-Cola magnate Asa Candler" is Hartsfield-Jackson Atlanta International Airport.
For Danielle Maurer, who lives in Peachtree Corners, it was a piece of cake. Not as obvious, however, to the 23-year-old defending champion Mattea Roach - who's from Toronto.
Maurer's correct response, and Roach's incorrect response, leapfrogged Maurer to victory by all of $1.
Roach, meanwhile, saw her winning streak end at 23. She earned $560,983 during her run on the game show and produced one of the five longest winning streaks in “Jeopardy!” history.
The final margin was Maurer's $15,600 to Roach's $15,599.
