Which prolonged conflict lasted from 1954 to 1975 and involved North Vietnam and South Vietnam with United States support?

• A. Gulf War
• B. International Conflict
• C. Cuban Missile Crisis
• D. Vietnam War

Answer: (D)

The key idea is recognizing a specific, long-running armed conflict with clear participants and a defined era. The Vietnam War fits this: it lasted roughly from 1954 to 1975 and pitted North Vietnam against South Vietnam, with the United States providing substantial support and troops for much of the fighting. The war began after Vietnam was divided following the Geneva Accords in 1954, escalated through the 1960s with extensive U.S. involvement, and ended with the fall of Saigon in 1975. This distinguishes it from the Gulf War, which occurred in 1990–1991; the Cuban Missile Crisis in 1962, which was a tense standoff rather than a prolonged war; and a generic term like an “International Conflict,” which does not name a specific historical event.
