While researching a topic, a student has taken the following notes:
·Body positions are a fundamental aspect of dance.
·In Vaganova method ballet, there is a position for the dancer's arms called first position.
·In the position, both arms are rounded to roughly align the fingers with the navel.
·In Royal Academy of Dance ballet, there is a position for the dancer's arms called demi-seconde position.
·In this position, both arms are out to the sides but angled downward.
The student wants to emphasize a similarity between the two positions. Which choice most effectively uses relevant information from the notes to accomplish this goal?
