How does dictation affect theme in a story

Which line in this excerpt from the great gatsby by f. scott fitzgerald contains a simile? about half way between west egg and new york the motor-road hastily joins the railroad and runs beside it for a quarter of a mile, so as to shrink away from a certain desolate area of land. this is a valley of ashes—a fantastic farm where ashes grow like wheat into ridges and hills and grotesque gardens where ashes take the forms of houses and chimneys and rising smoke and finally, with a transcendent effort, of men who move dimly and already crumbling through the powdery air. occasionally a line of grey cars crawls along an invisible track, gives out a ghastly creak and comes to rest, and immediately the ash-grey men swarm up with leaden spades and stir up an impenetrable cloud which screens their obscure operations from your sight.

In which part of this excerpt from the gettysburg address does president abraham lincoln argue that the outcome of the war will depend on the determination and loyalty of northern citizens? four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal. now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. we are met on a great battle-field of that war. we have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. it is altogether fitting and proper that we should do this. but, in a larger sense, we can not dedicate—we can not consecrate—we can not hallow— this ground. the brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. the world will little note, nor long remember what we say here, but it can never forget what they did here. it is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. it is rather for us to be here dedicated to the great task remaining before us— that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under god, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.
