premise: A ribbon dancer wearing a neon pink and green outfit with only one left white sleeve leaps high into the air- throwing her ribbon out before her in a "c" shape. hypothesis: A musician is practicing singing in front of the mirror naked.
contradiction: Is it a dancer or a musician? They aren't the same thing.   The person can't be leaping and practicing singing at the same time.   The person can't be naked and wearing a pick and green outfit at the same time.
