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?
