David Gregory "Dave" Smith (born 24 July 1955) is a retired male race walker from Australia, who represented his native country at two consecutive Summer Olympics, starting in 1980 (Moscow). His best Olympic result was finishing in tenth place in the men's 20 km race at the 1984 Summer Olympics.
David Gregory " Dave " Smith medaled in the 1980 Summer Olympics.
The statement is definitely incorrect because in order to medal you must place in the top three, the above context says his best finish was tenth in olympic competition. The system does not know olympic rules. I believe the question was poor and doomed to fail. I would have stated that he never medaled in competition and had a best tenth place finish in 1984.
