When we say trivia content is allowed, what we mean is that we allow questions that discuss issues that are relatively unimportant to the participation or enjoyment of the sport. For example, here is a recent question about trivia:
Olympic medalist in both the Summer and Winter Olympics
The answer doesn't really affect anyone who wants to enjoy watching or participating in the Olympics, but it is interesting information anyway.
That's not the same as a quiz question. If the question had been asked like this, it should have been voted out of existence:
Which of the following athletes has won a medal in both the Summer and Winter Olympics:
A. Michael Jordan
B. Brett Favre
D. Clara Hughes
We don't play multiple choice games here. As far as I know, this kind of question wouldn't be allowed on any StackExchange site.
