premise: The J.J. Deal and Son Carriage Factory was the largest factory built in Jonesville, Michigan. It is the only 19th century factory remaining in the City. It is located at 117 West Street. On August 1, 2012, the building was added to the National Register of Historic Places.
hypothesis: The J.J. Deal and Son Carriage Factory is the only building from the 1700s that stands to this day in Jonesville, Michigan.
reason: The J.J. Deal and Son Carriage Factory was built in the 19th century, so there is no way that it can be a building from the 1700s.
