Trivia: Which river starts in the Black Forest of Germany?
Rhine
Thames
Danube
Volga
The correct answer is Danube
So why is this answer correct? : Rising in the Black Forest Mountains of Germany and traveling through nine countries — Ukraine, Romania, Bulgaria, Serbia, Croatia, Hungary, Slovakia, Austria, and Germany — the Danube collects water from more than 300 tributaries along the way and empties into the Black Sea. The 1,700-mile Danube flows through more national capitals than any other river, including Belgrade, Vienna, Bratislava, and Budapest.
