Biggest City by Geographic Location

Thank you - it's a good quiz. If I may make a few comments/suggestions. Firstly, I think it could do with an extra minute - I certainly didn't get to the end, though admittedly I was eating an orange at the time. Isn't Istanbul bigger than Moscow (Europe Qn)? The India answer should be Delhi, rather than New Delhi. The Mediterranean is in the wrong place - should be with Seas, not Rivers. Lilongwe is not on the shore of Lake Malawi - I suspect that the answer to that question is Karonga or perhaps Nkhotakota. The Mountain Ranges and Deserts questions are difficult as their boundaries are unclear. For example, I don't think that Wien is in the Alps. Finally isn't Sao Paulo bigger than St Petersburg? If you meant the city had to be strictly "saint" in English, you should have said so.

This is a really cool quiz only thing is I think you should use urban areas and not city proper for american cities (such as Jacksonville being the largest city in Florida)

Cool quiz.

I disagree with your answer for three words, though, as officially that place has a name that is only two words (the third word is a colloquial add-on).

You forgot Lake Ontario and Toronto.

Awesome quiz! 5⭐ and nominated!

One minor quibble/question: I'm a bit confused about the answer of Bengaluru for the Deccan Peninsula. I will agree that it's unquestionably the biggest city on the Deccan Plateau. However the Deccan Peninsula (which I would argue is a far less common term) really encompasses pretty much all of southern India. For example, the Encyclopedia Britannica defines it as "the entire southern peninsula of India south of the Narmada River."

Per that definition, I would submit that Mumbai would be included and should qualify as the largest city?

Karachi is not directly on the Indus river but is instead located on a mouth of a river right next to the Indus

Great quiz! I had much fun, even if I could not finish it within the given time.

One point though: Istanbul as far as I know does not touch the Black Sea. It's actually located on the Marmara Sea side of the Bosporus strait. Unless you are considering the Bosporus strait itself as Black Sea, but that would be even more debatable.

All in all, I think this answer should be changed to (probably) Odessa in Ukraine.
