Suppose Jaws is a 1975 American thriller film directed by Steven Spielberg, based on Peter Benchley's 1974 novel of the same name. The film follows a police chief, a marine scientist, and a fisherman as they set out to stop a great white shark that is menacing the small island community of Amity.
Can we infer that "Bruce the Shark was a real great white shark trained for the film."?  Yes, no, or maybe?
