Which excerpts from "The Caged Bird" can be interpreted as part of the extended metaphor that represents freedom?

Explanation:

A metaphor is a figure of speech that allows the author of a text to present an implicit comparison between two elements. In a poem, this metaphor will be used in one or a few lines, but it will not be extended throughout the text, unless this is an extended metaphor. The extended metaphor expands the comparison to a long piece of text, or to the full text. In this case, the concept presented by the comparison is repeated throughout the text at different times, always pointing to the same subject. In the poem "The Caged Bird" written by Maya Angelou, we can see examples of the metaphor extended in the lines "downstream floats," "the trade winds soft" and "dawn-bright lawn," all of which reinforce the sense of freedom.
