Wallace Houston Terry, II (April 21, 1938 – May 29, 2003) was an African-American journalist and oral historian, best known for his book about black soldiers in Vietnam, "Bloods: An Oral History of the Vietnam War" (1984), which served as a basis for the 1995 crime thriller "Dead Presidents". Using only the above description and what you know about the world, "Wallace Houston Terry wrote several books, such as "Bloods: An Oral History of the Vietnam War" which served as the basis for movies later in his life." is definitely correct, incorrect, or inconclusive?
