Read the excerpt from act 4, scene 1, of The Tragedy of Julius Caesar.

[BRUTUS.] He is not doubted—A word, Lucillius.
How he received you let me be resolved.

LUCILLIUS. With courtesy and with respect enough,
But not with such familiar instances,
Nor with such free and friendly conference,
As he hath used of old.

BRUTUS. Thou hast described
A hot friend cooling. Ever note, Lucillius:
When love begins to sicken and decay
It useth an enforcèd ceremony.
There are no tricks in plain and simple faith;
But hollow men, like horses hot at hand,
Make gallant show and promise of their mettle;
But when they should endure the bloody spur,
They fall their crests and, like deceitful jades,
Sink in the trial.

Which central idea is reflected in this passage?

the impact of fate
the extent of loyalty
the ruthlessness of power
the importance of compromise

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.
