The first rays of sun illuminated the frost on the inside of the window. Jack knew then that the temperature had dipped below zero overnight. The tiny cabin on Mount Rainier was little more than a shack. It had smelled musty when he and Armando first entered it last night, but the strong odor of smoke from the fire filled his nostrils now. Jack was glad to see that Armando was sleeping on the tattered cot. His friend had fallen more than 30 feet onto a rocky ledge. Jack was certain that Armando’s leg was shattered.
Jack began to think of the treacherous route back to the nearest town. He would have to cross rugged terrain and frozen streams. But Jack knew that he would have to make it there today to find a doctor. Jack drew in a deep breath and began to pack. As his resolve grew, his shaking hands began to steady. He would not let his friend down.

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.
