Practice quiz with answers and explanations

**Practice Quiz: The Causes of World War I** (High school, medium difficulty) 1. (Multiple choice) Which event directly triggered the July Crisis of 1914? A) The sinking of the Lusitania B) The assassination of Archduke Franz Ferdinand in Sarajevo C) Germany's invasion of Belgium D) The Russian Revolution 2. (True/false) The alliance system helped keep conflicts local because each power only fought its own enemies. Justify your answer. 3. (Multiple choice) Which best describes "militarism" as a cause of the war? A) A belief that diplomacy should always replace force B) A build-up of armed forces and the idea that military strength should shape policy C) A treaty limiting the size of national armies D) A shared European army under joint command 4. (Short answer) Explain how imperial rivalry outside Europe added to tension between the great powers. 5. (True/false) Nationalism in the Balkans made Austria-Hungary's position more fragile. Justify your answer. 6. (Short answer) Why did the "blank cheque" Germany gave Austria-Hungary make a compromise less likely? 7. (Application) A mobilization plan depends on moving millions of troops quickly. Why might that make diplomacy harder in a crisis? 8. (Application) Historians disagree on whether the war was caused mainly by long-term structures or by short-term decisions. Which evidence from this topic would you use for each side? --- **Answer key** 1. B. Franz Ferdinand, heir to the Austro-Hungarian throne, was killed in June 1914, and Austria-Hungary's response set the crisis in motion. A is tempting but the Lusitania sinking happened in 1915, after the war began. 2. False. Treaties linked Austria-Hungary and Germany against Russia, France and Britain, so a Balkan dispute could pull in many powers. The tempting "True" ignores how obligations chained the powers together. 3. B. Militarism meant large armies, arms races and military leaders with real influence. C is tempting but it describes arms limitation, the opposite idea. 4. Competition over colonies and trade, for example in Africa and Asia, fed distrust and naval rivalry, especially between Britain and Germany. 5. True. Slavic nationalist movements, backed by Serbia, threatened the multi-ethnic empire, so Austria-Hungary treated Serbia as an existential danger. 6. Germany's promise of support removed pressure on Vienna to negotiate, so a harsh ultimatum to Serbia looked safe and compromise lost its appeal. 7. Fixed timetables leave little room to pause, so leaders feel they must mobilize first, and mobilizing can look like an act of war to rivals. 8. Structural: alliances, arms races, imperial rivalry. Short-term: the assassination, the blank cheque, the ultimatum and the mobilizations. A strong answer links the two. **Scoring guide** - 7-8 correct: solid grasp; try a source-analysis exercise next. - 4-6 correct: review the alliance system and the July Crisis timeline. - 0-3 correct: re-read a short overview of the war's origins, then retake the quiz.
