Historically, these kinds of questions were kept relatively simple, like how many bases are there, how many strikes, how many balls, how many innings, what's the name of the referee (answer: umpire), etc. They're also a product of a different time when baseball was much more popular in the US among US youth, with a much stronger youth monoculture, where the only way you didn't play baseball as a kid would be if you were a loner or in a wheelchair, neither of which were consistent with becoming an officer 80-90 years ago.
