I thought Tucson, AZ, was bigger than Turin, so after I hit Turin I typed Tucson over 5 times. Checked the source and found that I was monumentally wrong.
That was insanely difficult for me - I only got 9. I thought of a bunch that didn't work, like Kunming, Denver, Tulsa, Calcutta, and Hohhot. I feel some dumb seeing the answers, but trying to think of cities based on their letters was much harder than I would have thought.
Usually, the picture shown in the thumbnail is of the first answer on the page. But this picture of not of Tokyo, it is of Osaka. Not a mistake by any means, as they both appear on the list, but I just didn't want anyone thinking that the top picture was Tokyo. The world needs to know!
Before you critique the quiz, please look at the source. If he just took arbitrary numbers from random sources, there would be so many more complaints.
Not necessarily the biggest problem, but you might consider adding a city from Latin America, given thar there is not a single Latin American city on this quiz.
I think you misunderstood kalbahamut's comment. They meant include Rio de Janeiro, which is in Latin America, which would be under RI. Riyadh would then be the next most populous city starting with RI.
The Chicago area came oh-so-close to the 10 million person cutoff for "megacity" status but is now losing population.
Keep them coming!
i admit i tried more than twice chongqing and chengdu, but i got Turin!
