premise: The 2012 PGA Championship was the 94th PGA Championship, played August 9–12 at the Ocean Course of the Kiawah Island Golf Resort in Kiawah Island, South Carolina, southwest of Charleston. Rory McIlroy shot a bogey-free 66 (−6) in the final round to win his second major title by eight strokes over runner-up David Lynn.
hypothesis: The 2012 PGA Championship lasted seven days 
reason: The context states that the 2012 PGA Championship was played from August 9-12, so it did not last seven days. The system was likely confused by the dates of the Championship being given as August 9-12 rather than stating explicitly how many days it lasted.
