Explanation:

• Nationalism: A major cause of World War I, as intense national pride and rivalries (e.g., in Europe) fueled tensions. Not a direct cause of U.S. entry. So "Cause of World War I".
• Militarism: Build - up of military forces and glorification of war was a WWI cause (European powers). Not a direct U.S. entry cause. So "Cause of World War I".
• Unrestricted submarine warfare (Germany): Germany’s unrestricted submarine attacks on ships (including U.S. vessels) led to U.S. entry. Not a WWI - starting cause. So "Cause of U.S. entry into war".
• Imperialism: Competition for colonies/resources among European powers was a WWI cause. Not a U.S. entry cause. So "Cause of World War I".
• Zimmermann Telegram (intercepted): The telegram (Germany's proposal to Mexico against U.S.) was a key cause of U.S. entry. Not a WWI cause. So "Cause of U.S. entry into war".
