Read the excerpt from “take the tortillas out of your poetry.” my friend had concluded that if he took his language and culture out of his poetry, he stood a better chance of receiving a fellowship. he took out his native language, the poetic patois of our reality, the rich mixture of spanish, english, pachuco and street talk which we know so well. in other words, he took the tortillas out of his poetry, which is to say he took the soul out of his poetry. which best explains how anaya’s tone establishes his voice in the excerpt?

anaya’s tone is humorous, which reflects his desire to highlight the topic.
anaya’s tone is easy-going, which reflects his lack of concern about the topic. anaya’s tone is passionate, which reflects his strong feelings about the topic. anaya’s tone is joyful, which reflects his determination to celebrate the topic.

The right answer is Anaya’s tone is passionate, which reflects his strong feelings about the topic. Author Rudolfo Anaya embraces multiculturalism and bilingualism, and he is proud of his Mexican American heritage. So when a fellow writer told him that he thought that his chances of receiving a fellowship would increase if he deprived his poetry of his native language (its dialect, its idioms) and his cultural references (to traditions, festivities, ways of thinking, and so on), he, using a simile, and with the goal of stressing the extent of such a "desecration," compared that to removing the tortillas out of his friend's poetry, that is, its very essence, its soul, since a tortilla is a staple foodstuff in Mexican cuisine, one of the, if not the, most distinguishing ones. It is clear, from Anaya's words, that he feels strongly and vehemently about the topic.
