premise: The 1997 Porsche Tennis Grand Prix was a women's tennis tournament played on indoor hard courts at the Filderstadt Tennis Club in Filderstadt in Germany that was part of Tier II of the 1997 WTA Tour. It was the 20th edition of the tournament and was held from 6 October through 12 October 1997. First-seeded Martina Hingis won the singles title, her second consecutive at the event.
hypothesis: The 1997 Porsche Tennis Grand Prix was a women's tennis tournament played on indoor hard courts, that continued for more than a week.
reason: Based on the provided information, the 1997 Porsche Tennis Grand Prix was held from 6 October through 12 October 1997, so it lasted only 6 days, therefore the statement that it continued for more than a week is definitely incorrect. I thought that the system would get confused by the main part of the statement, which is correct, and only the end makes the statement incorrect.
