premise: Like the Roman: The Life of Enoch Powell is a 1998 book by the English writer Simon Heffer. It is a biography of the politician Enoch Powell. The title is taken from Powell's 1968 Rivers of Blood speech when Powell quoted Virgil's "Aeneid": "As I look ahead, I am filled with foreboding; like the Roman, I seem to see the River Tiber foaming with much blood".
hypothesis: Like the Roman: The Life of Enoch Powell is based on real events.
reason: The book is a biography, so based on someone's real life. The system probably doesn't know the meaning of the word biography.
