The correct answer is: "The world would probably not remember what happened at Gettysburg."
Everett's speech had 13,609 words and lasted two hours. In contrast, Lincoln's brief words summed up the war in two or three minutes, in ten sentences, and in less than 300 words.
Lincoln's few selected words resonated throughout the nation and throughout history, challenging Lincoln's own prediction that "the world will notice little, not much time will remember what we say here."
