World War I is sometimes referred to by what nickname?

• A. World War I
• B. World War II
• C. Korean War
• D. Vietnam War

Answer: (A)

The idea being tested is how major conflicts are commonly named or nicknamed. World War I is famously called The Great War, and also The War to End All Wars, reflecting how people once viewed its scale and hoped it would prevent future wars. Those well-known nicknames aren’t among the options, so among the given choices, the one that refers to the same conflict by its widely used label is the designation for World War I itself. The other labels point to different wars entirely (World War II, the Korean War, and the Vietnam War). So, within these options, the term that names the same conflict is the best fit.
