I was shocked about the Lidia Pereprygina question, so I looked it up. It seems that it's not confirmed, only rumored. And she was apparently 14 when the relationship started, not 13, not that it makes things better.
I completely agree with Quizmaster's first comment. Maybe a better move to limit the quiz to 10 questions in a similar style to the City Multiple Choice quizzes.
