Answer: B) Anaya structures his text as an explanation, which gives it an authoritative tone, while Nye structures her text as an impression, which gives it a soothing tone.
Step-by-step explanation: The tone of a text or sentence is the author's or speaker's attitude towards the audience, the subject or even the characters of the text. There are many different kinds of tones, like: positive, negative, objective, sad, angry, etc. In the first excerpt we can see an example of an authoritative tone produced by the structure of the text (Anaya explains why her friend took his language and culture out of his poetry). The second excerpt has a soothing tone produced by Nye's narration of her impression.
