[MC] WHAT TO THE SLAVE IS THE FOURTH OF JULY?By Frederick DоuglаssExtrаct frоm аn Oratiоn, at Rochester, July 5, 1852 Fellow-Citizens—Pardon me, and allow me to ask, why am I called upon to speak here to-day? What have I, or those I represent, to do with your national independence? Are the great principles of political freedom and of natural justice, embodied in that Declaration of Independence, extended to us? and am I, therefore, called upon to bring our humble offering to the national altar, and to confess the benefits, and express devout gratitude for the blessings, resulting from your independence to us? But, such is not the state of the case. I say it with a sad sense of the disparity between us. I am not included within the pale of this glorious anniversary! Your high independence only reveals the immeasurable distance between us. The blessings in which you this day rejoice, are not enjoyed in common. The rich inheritance of justice, liberty, prosperity, and independence, bequeathed by your fathers, is shared by you, not by me. The sunlight that brought life and healing to you, has brought stripes and death to me. This Fourth of July is yours, not mine. You may rejoice, I must mourn. To drag a man in fetters into the grand illuminated temple of liberty, and call upon him to join you in joyous anthems, were inhuman mockery and sacrilegious irony. Do you mean, citizens, to mock me, by asking me to speak to-day? . . . Fellow-citizens, above your national, tumultuous joy, I hear the mournful wail of millions, whose chains, heavy and grievous yesterday, are to-day rendered more intolerable by the jubilant shouts that reach them. If I do forget, if I do not faithfully remember those bleeding children of sorrow this day, "may my right hand forget her cunning, and may my tongue cleave to the roof of my mouth!" To forget them, to pass lightly over their wrongs, and to chime in with the popular theme, would be treason most scandalous and shocking, and would make me a reproach before God and the world. My subject, then, fellow-citizens, is AMERICAN SLAVERY. I shall see this day and its popular characteristics from the slave's point of view. Standing there, identified with the American bondman, making his wrongs mine, I do not hesitate to declare, with all my soul, that the character and conduct of this nation never looked blacker to me than on this Fourth of July. Whether we turn to the declarations of the past, or to the professions of the present, the conduct of the nation seems equally hideous and revolting. What does Douglass hold the nation accountable for? (5 points)

[MC] Fаll оf the Hоuse оf Usher, excerptBy Edgаr Allаn Poe Upon my entrance, Usher rose from a sofa on which he had been lying at full length, and greeted me with a vivacious warmth which had much in it, I at first thought, of an overdone cordiality—of the constrained effort of the ennuyé1 man of the world. A glance, however, at his countenance convinced me of his perfect sincerity. We sat down; and for some moments, while he spoke not, I gazed upon him with a feeling half of pity, half of awe. Surely, man had never before so terribly altered, in so brief a period, as had Roderick Usher! It was with difficulty that I could bring myself to admit the identity of the wan being before me with the companion of my early boyhood. Yet the character of his face had been at all times remarkable. A cadaverousness of complexion; an eye large, liquid, and luminous beyond comparison; lips somewhat thin and very pallid, but of a surpassingly beautiful curve; a nose of a delicate Hebrew model, but with a breadth of nostril unusual in similar formations; a finely moulded chin, speaking, in its want of prominence, of a want of moral energy; hair of a more than web-like softness and tenuity;—these features, with an inordinate expansion above the regions of the temple, made up altogether a countenance not easily to be forgotten. And now in the mere exaggeration of the prevailing character of these features, and of the expression they were wont to convey, lay so much of change that I doubted to whom I spoke. The now ghastly pallor of the skin, and the now miraculous lustre of the eye, above all things startled and even awed me. The silken hair, too, had been suffered to grow all unheeded, and as, in its wild gossamer texture, it floated rather than fell about the face, I could not, even with effort, connect its Arabesque expression with any idea of simple humanity. In the manner of my friend I was at once struck with an incoherence—an inconsistency; and I soon found this to arise from a series of feeble and futile struggles to overcome an habitual trepidancy—an excessive nervous agitation. For something of this nature I had indeed been prepared, no less by his letter, than by reminiscences of certain boyish traits, and by conclusions deduced from his peculiar physical conformation and temperament. His action was alternately vivacious and sullen. His voice varied rapidly from a tremulous indecision to that species of energetic concision—that abrupt, weighty, unhurried, and hollow-sounding enunciation—that leaden, self-balanced and perfectly modulated guttural utterance.1Bored Which portion of this passage indicates that the narrator observed Roderick Usher trying to appear cheerful and friendly, in contrast to his "terribly altered" appearance?

[MC] Lаdy Mаcbeth (Act 1; Scene V): Glаmis thоu art, and Cawdоr; and shalt beWhat thоu art promised: yet do I fear thy nature;It is too full o' the milk of human kindnessTo catch the nearest way: thou wouldst be great;Art not without ambition, but withoutThe illness should attend it: what thou wouldst highly,That wouldst thou holily; wouldst not play false,And yet wouldst wrongly win:thou'ldst have, great Glamis,That which cries 'Thus thou must do, if thou have it;And that which rather thou dost fear to doThan wishest should be undone.' Hie thee hither,That I may pour my spirits in thine ear;And chastise with the valour of my tongueAll that impedes thee from the golden round,Which fate and metaphysical aid doth seemTo have thee crown'd withal. Macbeth (Act 1; Scene VII): He's here in double trust;First, as I am his kinsman and his subject,Strong both against the deed; then, as his host,Who should against his murderer shut the door,Not bear the knife myself. Besides, this DuncanHath borne his faculties so meek, hath beenSo clear in his great office, that his virtuesWill plead like angels, trumpet-tongued, againstThe deep damnation of his taking-off;And pity, like a naked new-born babe,Striding the blast, or heaven's cherubim, horsedUpon the sightless couriers of the air,Shall blow the horrid deed in every eye,That tears shall drown the wind. I have no spurTo prick the sides of my intent, but onlyVaulting ambition, which o'erleaps itselfAnd falls on the other. Use the excerpts from Macbeth to complete the following task: Write an essay of at least three paragraphs, supporting the assertion that Lady Macbeth does not trust Macbeth to live up to his ambition. Be sure to include evidence from the text to support your answer. Remember to clearly state your main point and use correct citation in your response. (100 points)
