According to the material, what years encompass the Vietnam War?

• A. 1950–1970
• B. 1960–1975
• C. 1955–1975
• D. 1963–1975

Answer: (C)

The material frames the Vietnam War as a conflict that spans from 1955 to 1975. The starting point is tied to the moment when the United States began substantial involvement in South Vietnam beyond advisory aid, as the South Vietnamese government stabilized under Ngo Dinh Diem and U.S. support escalated. The ending point is the fall of Saigon in 1975, when North Vietnamese forces captured the city and Vietnam was reunified under communist rule, marking the end of large-scale U.S. military involvement. Other date ranges don’t fit the material’s timeline: starting earlier, like 1950, would include phases before clear U.S. involvement; starting later, like 1960, ignores the early advisory and support efforts beginning around 1955; ending earlier, like 1970, would omit the final years of fighting that culminated in 1975.
