After reading this except from leo tolstoy’s the death of ivan ilyich I've recognized the sentence which shows that ivan ilyich’s daughter, lisa, does not empathize with her father’s suffering almos in the end of the excerpt. I am pretty sure that this sentence best shows what you need.
"it's as if we were to blame! i am sorry for papa, but why should we be tortured?"
He tells Percy the story about the tree and a girl named Thalia. The story was that Thalia, Annabeth and other half bloods where exploring outside of the half blood camp. But then monsters came out of nowhere and started fighting them. They tried to fight the monsters but they weren’t strong enough. So Thalia protected them and risked her own life to save them. But thalia died and Zeus her father grew a tree in her honor, and the tree provided a barrier for the camp to keep them safe. :-)
The sentence is drawing a parallel between the two parties' reasons for going to war. Each of them is associated with a verb: one with "survive," the other with "perish." They are the two antonyms.
Antonyms are words which have opposite meanings. <em>Survive </em>means to contine living, and <em>perish </em>means to stop living.
What Lincoln meant by using this antonym-based parallelism is that the Confederacy fought to end the exisiting nation (meaning, to secede from the North and create a new nation), while the Union fought to keep the nation alive by preventing it from splitting.
B is the correct answer. The positives will repel one another, and the positive and the negative will attract. Almost said A, but in that case, the two positives would be attracted to the negative.
In cases such as this, remember, opposites attract, and same charges counter-act
