Excerpt from the gettysburg address
abraham lincoln

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 this earth.
the rhetorical strategy that lincoln used when he wrote the phrase "of the people by the people for the people shall not perish from this earth" is known as
a) simile.
b) metaphor.
c) parallel structure.
d) subject-verb agreement.
