Answer:
I think that the tone of this passage is regretful. The correct option in the last one.
Step-by-step explanation:
In these lines, the author tells how he/she perceives the reality of the white South Africans, he/she says that they are afraid of losing privileges, and that they "would rather die” than give up those privileges. These words are filled with sorrow, with sadness and without hope. The author tells this as a hard truth, but truth at last. The author is not violent in this description, he/she is just pointing out the reality and that is why I chose regretful as the correct tone for describing the excerpt. The author is not directly judging the white South Africans acts, he/she is just giving information with a connotation of sorrow and regret.
