Suppose Serena Williams (born September 26, 1981) is a professional tennis player. She has won 23 Grand Slam singles titles and is considered one of the greatest female tennis players of all time. In 2017, she won the Australian Open while pregnant with her daughter, Alexis Olympia Ohanian Jr.
Can we infer that "Serena Williams only competes in singles events."? Yes, no, or maybe?
