Final answer:
The question presents an ambiguity since the role of a ballerina is not typically associated with singing. The reference to a beautiful voice could metaphorically relate to the expression of artistic talent such as dance. The given texts suggest admiration for the artist's talent while also critiquing the lack of substance or sincerity.
Step-by-step explanation:
The question, "What does the ballerina do regarding her beautiful voice?" is somewhat ambiguous, as ballerinas are primarily known for their dance performances, not their vocal abilities. However, referring to the provided texts, we can discern that the reference to a beautiful voice may relate to a female performer or artist who is admired for her artistic talent, which could include dancing gracefully to music, enchanting others with her performance, or even captivating an audience with her singing.
Despite the artistic abilities of these performers, the last text suggests a criticism of such artists, implying that they have style but lack sincerity and substance. This criticism comments on the nature of some artists who focus solely on their craft and its aesthetics without a deeper emotional connection or practical contribution to others.
It is important to note that in classical performances, dancers and singers often collaborate to bring a cohesive artistic presentation, with each artist contributing their unique skills to the overall experience. While the ballerina might not typically sing, her performance could still evoke a beautiful voice through movement, interpreting the music and expressing emotions without words.
