The best response to how the analogy in this excerpt helps develop meaning in the text is:
It expresses that Romeo’s good qualities are an inherent part of him and more important than his name.
This choice highlights Juliet's realization that Romeo's identity and worth are not defined by his family name (Montague) but by his character. This reflection on the insignificance of names in contrast to the essence of love underscores one of the central themes of the play—the conflict between personal identity and societal expectations.
