premise: Sam (November 7, 1990 – November 18, 2005) was a blind pure-bred Chinese Crested hairless and toothless dog, and three time champion of the annual Sonoma-Marin Fair World's Ugliest Dog Contest in Northern California in 2003–2005. His ugliness gained him international fame and celebrity – his death was a top headline on major news websites.
hypothesis: Sam the three time ugliest dog winner lived for a little over 15 years.
reason: Sam was the ugliest dog winner in Northern California and he did live for 15 years and 11 days. I think this was difficult for the system due to the complexity of what I wrote.
