The correct answer to the Solos, Duets, & Trios quiz is False (the USASF Dance Rules do not govern solos, duets, and trios). The Dance Age Grid states that a dance team must have 4-14 dancers to compete in the Small Division and 15 or more dancers to compete in the Large Division. Therefore, the USASF does not govern solos, duets, and trios. While there is no limit to the maximum number of dancers that may compete in the Large Division there is a minimum in both the Small and Large Divisions.
The explanation is based on the 2017-18 version of the dance rules dated August 30, 2017.
