Suppose Serena Williams, an American professional tennis player, has won 23 Grand Slam singles titles, the most by any man or woman in the Open Era. She has been ranked world No. 1 in singles by the Women's Tennis Association on eight separate occasions. Serena has also won four Olympic gold medals, one in women's singles and three in women's doubles.
Can we infer that "Serena Williams has never won an Olympic gold medal."? Yes, no, or maybe?
