The best response to the question about how the analogy in the excerpt from Shakespeare’s "Romeo and Juliet" 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 interpretation aligns with Juliet's sentiment that Romeo's identity, marked by his family name, should not define the essence of who he is or the love they share. It highlights the idea that love transcends social labels and familial affiliations.
