Answer:
any nation so conceived and so dedicated
we cannot dedicate . . . we cannot consecrate . . . we cannot hallow this ground
of the people . . . by the people . . . for the people
Step-by-step explanation:
In the first example, Lincoln modifies the word nation with the adjectival phrases "so conceived" and "so dedicated." The adjectival phrases have the same form.
In the second example, he repeats the phrase “we cannot” followed by different verbs to give an added element of parallelism.
In the third example, he repeats “the people” to emphasize the government represents everyone after the war.
