Today's Geo Quiz begins in Germany's Black Forest. The river we want you to name picks up speed in Germany and flows east for 1771 miles, making it the second longest river in Europe, just behind the Volga River. The river flows through 10 countries before it empties into the Black Sea. Along the way it passes through several Central and Eastern European capitals. Budapest, for example, straddles this river.

The city's many bridges offer a panoramic view. You can hear more about a plan Budapest has to rid those bridges of graffiti...so you won't be distracted while you're enjoying the view of the river.
The name of that river is a click away, just up around the bend.
