premise: Stainer & Bell Limited is a British publisher of classical sheet music and books, based in London. Stainer, founded in 1907, publish the works of a number of significant twentieth-century composers, including Charles Villiers Stanford, Gustav Holst, Ralph Vaughan Williams, and Herbert Howells. They also publish a number of earlier composers, including Henry VIII, William Byrd, and Henry Purcell.
hypothesis: Stainer & Bell Limited was founded after the War of 1812.
reason: The war of 1812 began in 1812 and did not last over 95 years while Stainer & Bell Limited was founded in 1907.  I think this was difficult for the system because I introduced a new year into the statement.
