Arnold Rampersad (born 13 November 1941) is a biographer and literary critic, who was born in Trinidad and Tobago and moved to the US in 1965. The first volume (1986) of his "Life of Langston Hughes" was a finalist for the Pulitzer Prize and his "Ralph Ellison: A Biography" was a finalist for the 2007 National Book Award. Using only the above description and what you know about the world, "Arnold Rampersad was was 29 years old when he moved to the United States." is definitely correct, incorrect, or inconclusive?
