Which rivers originate from the Valdai Hills?

The rivers that originate from the Valdai Hills are indeed the Dnieper and the Volga. The Valdai Hills, located in northwest Russia, serve as a significant watershed that generates multiple important rivers in the region.

The Volga River, one of the most well-known rivers in Russia and the longest in Europe, flows westward from the Valdai Hills, making it vital for transportation and cultural significance in the country. The Dnieper, which flows southward into the Black Sea, also has its sources in the same geographical area, demonstrating the importance of the Valdai Hills as a starting point for major waterways in Eastern Europe.

In contrast, the Lena and the Yenisei, the Kama and Ural, and the Amur and Don have different origins and do not spring from the Valdai Hills, which is why the other options do not accurately reflect the correct answer.
