Read the following passage
 Four score and seven years ago our fathers brought forth, upon 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 haliow - this ground. The
 brave men living and dead, who struggled here, have consecrated it for 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 here 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
