premise: "The Orange and the Green" or "The Biggest Mix-Up" is a humorous Irish folk song about a man whose father was a Protestant ("Orange") and whose mother was a Catholic ("Green"). It describes the man's trials as the product of religious intermarriage and how "mixed up" he became as a result of such an upbringing.
hypothesis: The Orange and Green is another name for the song titled A Big Mix-Up
reason: The system is wrong because it isn't picking up the subtleties of the name. "The Biggest Mix-Up" is not the same as "A Big Mix-Up" so saying this is another name for the song is wrong.
