Which global conflict lasted from 1914 to 1918 and involved widespread casualties and upheaval?

• A. American Civil War
• B. World War I
• C. Korean War
• D. Vietnam War

Answer: (B)

Understanding how to recognize a major global conflict by its time frame and impact. The period from 1914 to 1918 is the defining window of World War I, a total war that drew in countries from around the world and caused widespread casualties and upheaval both on the battlefront and at home. The war began with a cascade of alliance mobilizations after the assassination of Archduke Franz Ferdinand, leading to trench warfare, rapid technological change in weapons, and sweeping social and political changes across many nations. It ended with an armistice in November 1918 and reshaped borders, governments, and international relations in the years that followed. The other conflicts listed occurred at different times and places and do not match this global scale and the specific 1914–1918 timeframe.
