A) Mandela's use of the word "must" indicates his conviction that renewal is necessary.
Explanation:
In this sentence from "Mandela's Inaugural Address", Mandela alludes to times of Apartheid by calling it an experience of extraordinary disaster. In the next part he demands for society of which all humanity should be proud (a society in which all human beings all races have equal rights).
His use of "must" shows his conviction that such a society has now become necessary.
Option B is incorrect because that experience was disastrous and there is no value or good things about such an experience.
Option C is incorrect as the phrase "human disaster that lasted too long" shows no such future plans, it just alludes to a grim past experience.
Option D is incorrect because "extraordinary" is used with an experience no one likes to have, and "proud" is used when talking about future plans. So, it shows nothing about his satisfaction with his country.
B because the word very is showing how well he is smart and helping to explain.
