premise: Foreign folk dancers are dressed in outfits of bright lime green, red and white tops, lime green headbands and red, blousy trousers and open-toed specialty shoes while dancing in a city street, while spectators enjoy the show. hypothesis: A pop girl band is dancing in sync.
contradiction: The people should either be dancing as part of a pop girl band or foreign folk dancer, but not both, since they are different styles of dancing.
