The correct answer is:
The voice affects consistency of tone and the amount of bias revealed.
Explanation:
Voice, in literature, is what we hear when we read the work of a specific author, it is created by the format of the author's writing, while in a spoken language it would be the sound of the voice.
Tone, on the other hand, is the attitude and feelings of the author towards the writing, and it is reflected in the choice of words of the writer to express those feelings to the audience, in a spoken language it would be the actual tone of the voice when someone speaks. Voice affects consistency in tone and the amount of bias revealed because the format used to write a suspense novel, or an ironic comedy would change to express the actual purpose of the writing.
Answer:
The correct answer would be option b:"The author once felt pride and optimism about the war".
Explanation:
In the excerpt, the author says that "he was proud of the young American pilots sitting at the controls in the cockpit" and that "he was grateful for the opportunity to witness this adventure and report it".
It just says that he was excited to get on a U.S Army helicopter, it does not say nor infer that is was his first flying experience, therefore, option a is incorrect.
It doesn't say and it cannot be inferred that the U.S soldiers are trained in hand to hand combat, so option c is also incorrect.
The author barely mentions the Vietcong guerillas, and he does not seem to have any respect for them since he was excited about war, so option d is also incorrect.
