premise: Peter Murray Kapetan was an American Broadway actor, singer and dancer notable for playing numerous roles during a thirty-year career. He was notable for performing in the musical "The Wedding Singer" as a Ronald Reagan impersonator. He appeared in "Titanic", "Sunset Boulevard", "Joseph and the Amazing Technicolor Dreamcoat", and "Got Tu Go Disco".
hypothesis: Peter Murray Kapetan had a long career, not quite a 40 year career, since he retired ten years before he would be in the show business for the full 40 years
reason: He had a thirty year career, that is ten years less than 40 so my statement was correct, maybe the system gets confused when it comes to counting
