I added the geographical clue, because the earlier version of the quiz seemed too hard. The average number of correct answers there was 3 out of 20. I added an extra minute to the time. I hope it'll be easier now.
ONE MORE UPDATE - You don't have to put the answer in the corresponding box anymore. I realize this would help to get more results with simply guessing, but this doesn't bother me since the current average is 5.
The position of the continents is taken from the "Countries of the world" quiz.
Thank you for the feedback! :) I changed the quiz a bit. Now you don't have to put the answers in the corresponding box. I hope that this will help a bit. :)
