premise: Judy Tegart Dalton (née Tegart; born 12 December 1937) is a retired professional tennis player from Australia who won nine Grand Slam doubles titles. She won at least one women's doubles title at each Grand Slam tournament, a "career Grand Slam". Five of her doubles titles were with Margaret Court. Tegart was the runner-up in 10 Grand Slam doubles tournaments.
hypothesis: Judy and player Margaret Court played on the same doubles team in tournaments.
reason: Five of her doubles titles were with Margaret Court, so we know Judy played on the same team with Margaret at least some of the time. The system might think the question is asking about ALL tournaments, but the question doesn't ask that.
