Explanation:

President Abraham Lincoln should only say a few words after the keynote speaker addressed the public at the Gettysburg Military Cemetery dedication ceremony. Here, a few months ago, there had been one of the bloodiest and most crucial battles between the United States and the Confederacy. In less than two minutes the statesman honored the dead and gave purpose to American democracy with one of the most important speeches, the Gettysburg speech.

In this speech, Lincoln emphasized the importance of unity, honored the dead who will fight in battle, and issued the Emancipation Proclamation to free enslaved states in Confederate states.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
