A few notes: Lake Vostok is accepted for Australia because it lies in a part of Antarctica claimed by Australia. GDP data is from International Monetary Fund. City population is for urban areas. For the purposes of this quiz, the Caspian Sea is considered a lake, although Lake Baikal is accepted for Asia. Russia is generally considered the largest country in Europe, so it is accepted. Also Denmark (largest European country outside of Russia) and France (largest country fully in Europe) are accepted. |
