Explanation: The alliances that led to World War I were the Triple Entente (Great Britain, France, and Russia) and the Triple Alliance (Germany, Austria-Hungary, and Italy). Serbia was supported by Russia, which needed access to (winter) warm-water ports. As part of the Triple Entente, France supported Russia (B). World War I may well be known as a “politicians’ war,” but the cartoon does not show this (A). World War I is aptly named, as it involved non-European countries (D).
