premise: The Granada Theater is a theatre located in Lower Greenville, in Dallas, TX. The theatre was built in 1946 as a movie house. In 1977, it was converted to a concert hall, only to revert to a movie theater soon after. In 2004 it was again opened as a concert hall.
hypothesis: The Granada Theater started out as a concert hall.
reason: While the Granada Theater has been a concert hall, the example states that it originally opened as a movie theater. I don't know why this answer fooled the AI.
