The Vietnam War began in 1954 and concluded with the unification of Vietnam in 1975. Step 1: Identify the start year of the Vietnam War from the passage. The passage states, "The war began in 1954". Step 2: Identify the end year of the Vietnam War from the passage. The passage states, "the country was unified as the Socialist Republic of Vietnam the following year [after 1973]", which means 1974 or 1975. Given the context of the war ending with unification, 1975 is the generally accepted end year for the conflict. Step 3: Calculate the duration of the war. Duration = End Year - Start Year Duration = 1975 - 1954 = 21 years. Step 4: Compare the calculated duration with the given options. The calculated duration of 21 years matches one of the options. The correct option is 21 years.
