Can you name something in the geographical category that begins with each of the given letters?
Deserts must be over 50,000 km, Religions over 1 million followers, Cities over 1 million people, Islands over 25,000 sq km, Lakes over 3,000 sq km, Rivers over 1,000 km,
The quiz description says cities of over 1 million people only are counted. I know, I was frustrated too when Hakodate for Japanese H cities and Annapolis for American A cities weren't being accepted until I saw that.
