Answer:
"Outraged" and "satisfied" are the adjectives that can be used to describe the tone of the text.
Explanation:
The text presents a change of tone in the course of its narration that justifies the use of two adjectives to describe it. the words "outraged" and "satisfied", reflect well the tone created by the author and the change in tone that can be observed.
At the beginning of the text we can see that the author used an indignant tone to present his ideas. This is because he shows and criticizes the way in which the history of blacks was erased, his contributions to America were disregarded and how it served to dehumanize blacks and affirm concepts that devalue them and make them expendable to society.
However, the author presents a tone of satisfaction, when he shows that after struggles, the history of blacks is being rescued and built in a strong and efficient way. In addition, he presents how blacks are managing not only to show, but to prove their importance, even in the midst of so much prejudice that still exists.
