Question

read the excerpt from abraham lincolns gettysburg address. but, in a larger sense, we cannot dedicate—we cannot consecrate—we cannot 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. lincoln uses parallelism in this excerpt to
acknowledge the limitations of the memorial ceremony.
criticize the audience for its disinterest in the war.
encourage soldiers to continue the fight for national unity.
emphasize the need for improved military strategy.

Explanation:

Parallelism is a rhetorical device. In this excerpt, Lincoln uses "we cannot dedicate—we cannot consecrate—we cannot hallow" to emphasize the significance of the soldiers' sacrifice. The world may not remember the words spoken at the ceremony, but it will remember the soldiers' actions. This is to encourage soldiers to keep fighting for national unity.

Answer:

encourage soldiers to continue the fight for national unity.
