I originally planned to use precise measurements for this quiz, but that ended up taking more time than I had, so I eyeballed it instead. If you think you have a *compelling* justification for one of these answers being wrong (something more than just "It looks different to me"), please let me know in the comments.
The quiz skews heavily toward Europe because I wanted to focus on capitals people are more familiar with, so I restricted my options to only ones that were guessed at least a certain percentage of the time on the Capitals of the World quiz. That meant a lot of Europe, and not much Africa or Oceania.
