Context: The commercial and geopolitical importance of rivers is not ranked here. As a transportation artery, a river may unite a region commercially and economically, but major rivers, as barriers to travel, may also form political boundaries between states. The Danube, the second longest river in Europe, is notable for flowing through or past ten countries; the Rhine through or past six. The Volga, the longest river in Europe, unites a huge region of European Russia; eleven of the twenty largest cities in Russia lie on its banks. The Loire and the Po unite important regions within France and Italy respectively. The most important rivers in Europe include Rhone, Elbe, Oder, Tagus, Thames, Don and Dnieper, among others.


Question: Given this paragraph about rivers in Europe, tell me what are the two longest rivers in Europe.
