Which statement best reflects the causes of World War I as described in the material?

• A. Diplomatic failures only
• B. A single assassination
• C. Divisions created by European alliances, nationalism, diplomatic failures, imperialism, competition over colonies, and militarism
• D. Economic depression alone

Answer: (D)

A web of long‑term, interlocking tensions across Europe created the conditions for a large-scale war. Alliances divided the continent into competing blocs, so a conflict with one country could quickly involve others. Nationalism fueled ambitions and rivalries, while imperialism and competition for colonies intensified rivalries among the great powers. Militarism made the buildup of armed forces and the belief in war as a tool of national policy feel normal, and diplomatic failures—miscommunication, brittle alliances, and rigid mobilization plans—turned a regional crisis into a continental one. The assassination of Archduke Franz Ferdinand was the immediate spark, but the broader pattern of rivalries and tensions is what really explains why a single incident escalated into a world war. That's why the statement that combines these factors best captures the causes. Other options fall short because they single out just one element or reduce the causes to a single event or condition, which ignores the complex, interconnected nature of the tensions that built up over time.
