why not accept the location for highest temperature? Lots of people would know Death Valley. Nobody is going to remember 56.7 exactly...
similarly, I don't know what the combined NFL score means, but maybe ask for the player or team and not the score? And I would have gotten Marilyn vos Savant but I didn't feel like guessing 228.
Lottery jackpot exact figure and the fall are not things people would remember... you could ask for the person who won and survived in each case but even then it's not anybody famous.
Is the "of the Armies" part of General really necessary? Is that different than "General?" I tried that... 5 star general... admiral.. president... commander in chief... then gave up. ... okay then I looked it up and apparently it's a thing but it's only been conferred twice in history and one of those two times the title was given to a dead guy. Seems almost like it shouldn't be considered.
