Which event is described as the WW1 Crisis involving Austria blaming Serbia, issuing an ultimatum, Russian involvement, and Germany declaring war on Russia?

• A. Treaty Of Versailles
• B. Cambodia Genocide
• C. Pearl Harbor
• D. WW1 Crisis

Answer: (D)

Understanding how a regional diplomatic crisis can spiral into a global conflict helps here. The situation described matches the July Crisis of 1914, when Austria-Hungary blamed Serbia for the assassination of Archduke Franz Ferdinand, issued an ultimatum, Russia mobilized in defense of Serbia, and Germany declared war on Russia. Those escalating moves—blame, demand for concessions, and mobilization within a web of alliances—pulled the major powers into World War I. The other options don’t describe this sequence: the Treaty of Versailles is the postwar peace treaty; the Cambodian Genocide occurred in a different time and place; Pearl Harbor was a WWII event. So the described event is the WW1 Crisis, the crisis that sparked World War I.
