Thank you for your comment. For this quiz, I had to choose 50 notorious rivers and this choice was obviously subjective. But if you want more, try my "100 rivers" version, you will find Sao Francisco River there ;)
Maybe Madeira River is indeed not so famous, but it is a verry important river, the first tributary of the Amazon in terms of length and discharge. (Twice the discharge of Mississippi!) It's why I wanted to put it here.
For the Sao Fransisco, I hesitate with 3 or 4 other rivers, but finally decided not to keep it, even if I know it's necessarily an arbitrary choice. I hope you still enjoyed it!
Great quiz, nominated. I have been trying to get all 100 on your harder version, but this was a nice smaller test. A random version (50 of the 100) would be amazing if you were up for the challenge!
