This isn't a bad quiz at all, though it does have some problems.
first of all, you phrased some of the questions very oddly... but based on the Author Comments, I see that English is most likely not your first language.
Also, once you finish the quiz, you should give the option to restart it without having to refresh the page. the coding for a button to bring you back to frame one is incredibly simple, so there's no excuse for that. Also, at the end, it would be nice if you, as the quiz-maker were to give us the percentage of the answers we got right.
if you were to do all of that, you'd significantly improve your game.
