premise: A group of people in white sports outfits are gathered together while one of them performs a dance.
hypothesis: The group is gathered to take turns performing a ritual dance.
explanation_1: Just because only one person is currently dancing does not imply that the others will take turns dancing as well.  Not all groups of people dancing are performing ritual dances.
explanation_2: Just because a group of people are gathered together and one of them performs a dance it does not mean they are taking turns in a ritual dance.
explanation_3: The dance is not necessarily a ritual dance.
