Are you sure it was a Final Jeopardy question? During the commercial break before Final Jeopardy, the contestants are told, and allowed to write on their screens, the correct interrogative word (Who, What, Where, When, etc.) that will begin the Final Jeopardy question.
It was absolutely FJ. She had written down the two states, but forgot to put “What are” in front of it.
This was several years ago, so maybe the reminder is a recent addition?
Only if the Argentinians had won.
They’ve done since at least late 1994, which was the first time I was on. I suppose it’s possible that she was distracted during the commercial break and forgot to write down the “What” part when the contestant coordinators came around.
