Final answer:
Nye crafts her voice by relating a personal encounter that underscores the importance of heritage. Meanwhile, Anaya's voice emerges through his discussion on the consequences of stripping cultural elements from creative works. Both authors use narrative structures to convey powerful messages about individual and cultural identity.
Step-by-step explanation:
In the excerpt from "Speaking Arabic," Nye utilizes narrative to encapsulate and deliver her perspective on heritage. She achieves this through the artful structure of juxtaposing mundane elements of a fair, such as food booths, with a profound moment of personal longing for heritage overheard at the event. This method heightens her voice by providing a slice of life that resonates with the theme of heritage and its significance. Consequently, the option that best explains Nye's text structure helping to establish her voice in the excerpt is that Nye relates a story about something she heard to emphasize the point she wants to make about heritage.
Regarding Anaya's excerpt from "Take the Tortillas out of Your Poetry," the text structure is pivotal in establishing his voice as it conveys a personal anecdote that reflects cultural sacrifice and authenticity. Anaya uses his friend's experience of removing his own cultural markers from his poetry to illustrate the broader issue of cultural identity and integrity within the artistic process. Thus, the option that best explains how Anaya’s text structure establishes his voice in the excerpt is that he employs a narrative style to underscore the dilution of cultural identity and the adverse impact this has on the soulfulness of art.
