 "Field Trip" questions, introduced in the third season, feature a video clip of a National Geographic Channel correspondent asking the question from an appropriate location somewhere in the world.In the 2015 revival, the $10,000 question also rewarded $10,000 to a grade school (connected to the studio via Skype) towards refurbishments and improvements if the contestant answered correctly.Upon reaching the final question, several rules changed slightly for the final question.
