Macbeth is both excited and fearful after hearing the witches predictions about his future because the witches told Macbeth that he would be king, and he is worried about his role in making the prediction come true.
The correct option is: by using short, punchy phrases.
Explanation
In this case, the writer (Lewis Carroll), uses a sentence structure that is short with punchy phrases to speed up the pace of the writing, instead of using long sentences.
As a result, while you read the passage, it gives you a sensation of speed and produces more impact on the reader.
The central idea of the paragraph in this exceprt the author adopts is that her parents barely dealt with the circumstances of living under a dictatorship despite the humiliating tributes done by Trujillo they unwillingly made part of, so the best idea is the last option "<em>The author’s parents tried to get by in the dictatorship, but felt humiliated by the tributes they were forced to participate in."</em> As expressed in the passage, the author's parents tried to keep a low profile to avoid detection from police, but having a handful of daughters made it difficult, and they could not take any risks but to accede to stand the dictatorship.
