premise: Brazilian mime is playing the racket as a guitar for his solo performance on the streets of Brazil in this picture. hypothesis: A Brazilian entertainer is in the middle of a festival, entertaining the photographer.
neutral: Just because someone is performing on the streets, it does not mean that he is in the middle of a festival. People can perform on the street without there being a festival. It also does not follow that he is doing so for the purpose of entertaining the photographer. A street performer might be performing to entertain a crowd.
