C

Explanation:

A) He uses short sentences to highlight the critical nature of the moment

Explanation: We can automatically rule our B) and C). This is because the text mentions no desire to erase the past, nor does the tone signify that. D) would also not work because Mandela's credibility is not being put in doubt in this article, and his tone does not signify defensiveness of his credibility. That leaves us with A). The repeated sentences all contain contents that point to change, and uprooting a corrupt system, which is urgent.

Hope this helps!

glamis thou art, and cawdor; and shalt be what thou art promis'd; yet do i fear thy nature; it is too full o' the milk of human kindness to catch the nearest way: thou wouldst be great; art not without ambition; but without the illness should attend it. what thou wouldst highly, that wouldst thou holily; wouldst not play false, and yet wouldst wrongly win: thou'dst have, great glamis, that which cries, "thus thou must do, if thou have it: and that which rather thou dost fear to do than wishest should be undone." hie thee hither, that i may pour my spirits in thine ear; and chastise with the valor of my tongue all that impedes thee from the golden round, which fate and metaphysical aid doth seem to have thee crown'd withal.
