premise: Keith Martin (1969 or 1970 – December 5, 2014), one of the world heaviest lived people, was famous for being at one point the UK’s heaviest man, weighing approximately 980 lbs at his peak. Keith Martin was given a gastric bypass operation by the NHS, and had lost over 50% of his body weight.
hypothesis: He was 500 pounds in 2002
reason: Its unknown what is weight was in 2002, therefor not being correct or incorrect. I think the model is confused by the fact that i put 500 pounds when the original statement has 980 in it.
