premise: Leila Meskhi (Georgian: ლეილა მესხი ; born 5 January 1968) is a retired Georgian professional female tennis player. She was ranked World No. 12 on 5 August 1991. Her best performance at a Grand Slam came when she got to the quarter finals of the 1990 US Open, defeating Akiko Kijimuta, Natasha Zvereva, Katia Piccolini and Linda Ferrando before losing to eventual champion Gabriela Sabatini.
hypothesis: Leila was 22 during the 1990 US Open.
reason: it is correct because 1990 minus 1968 is 22 but the AI thought new information was added so marked it as neither.
