premise: Vinaròs Club de Fútbol is a football team based in Vinaròs, in Castellón province, autonomous community of Valencian Community, Spain. Founded in 1965, it plays in Regional Preferente – Group 1. Its stadium is "El Cervol", which has a capacity of 9,600 seats.
hypothesis: The football stadium "El Cervol" was built in 1965 B.C.
reason: I added B.C. to the year.  Instead of 1965 A.D., I called it 1965 B.C..  Maybe the system hasn't been taught to recognize that way of labeling years.
