Walker, who knew nothing about horses, inherited Aberlone, a thoroughbred colt whose disagreeable behavior made him a pest around the barn. Walker sold the colt for $1,500 to Sherwood, an experienced racehorse-trainer who knew of Walker's ignorance about horses. At the time of sale, Walker said to Sherwood, "I hate to say it, but this horse is said to Sherwood, "I hate to say it, but this horse is bad-tempered and nothing special." Which one of the following scenarios would best support an action by Sherwood, rather than Walker, to rescind the sale? 
In his first race after the sale, Aberlone galloped to a huge lead but dropped dead 100 yards from the finish line because of a rare congenital heart defect that was undiscoverable except by autopsy.  Aberlone won $5 million for Sherwood over a three-year racing career but upon being retired was found to be incurably sterile and useless as a breeder. After Aberlone had won three races for Sherwood, it was discovered that by clerical error, unknown to either party, Aberlone's official birth registration listed an undistinguished racehorse as the sire rather than the famous racehorse that in fact was the sire.  A week after the sale, Aberlone went berserk and inflicted injuries upon Sherwood that required his hospitalization for six months and a full hospitalization for six months and a full year for his recovery.
