The option that best describes how Anaya effectively uses rhetoric in the excerpt to convince readers that his conclusion is justified is:
B) Anaya establishes his credibility as a published Chicano author by discussing his career experience.
Explanation:
Rhetoric concerns the use of devices and strategies to convince the audience of your opinion or perspective. A commonly efficient way to do so is by establishing your own credibility concerning the subject. That is what Anaya is doing in this excerpt. He gets to talk about language and culture in American literature, and be taken seriously while doing it, due to his credibility as a published Chicano author. His life and career are devoted and dependent on this subject, which gives him some sort of authority to discuss it.
'Horse of another color' is the opposite expression from Shakespeare's 'a horse of that color' in the Twelfth Night Act 2 Scene 3 where Maria told Sir Toby Belch that her purpose was indeed a horse of that color which meant that Sir Toby Belch got the same idea as hers. So, 'horse of another color' is an idea different from the other.
