premise: Ailes Gilmour (January 27, 1912 - April 16, 1993) was a Japanese American dancer who was one of the young pioneers of the American Modern Dance movement of the 1930s. She was one of the first members of Martha Graham's dance company. Ailes' older brother was sculptor Isamu Noguchi.
hypothesis: Ailes Gilmour's older brother was a sculptor and a dancer.
reason: Ailes Gilmour's brother was definitely a sculptor, but it doesn't say whether or not he was a dancer too, so it may or may not be correct. The system probably just saw the most key phrases and assumed it was correct.
