In paragraph 4, which rhetorical device does lincoln use to emphasize that everyone has a stake in the war?

This was the missing excerpt:
Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible, and pray to the same God; and each invokes his aid against the other. It may seem strange that any men should dare to ask a just God’s assistance in wringing their bread from the sweat of other men’s faces; but let us judge not, that we be not judged. The prayers of both could not be answered—that of neither has been answered fully.

This was the missing choices:
A)logical fallacy
B)extended metaphor
C)parallel structure
D)rhetorical question

The rhetorical device Lincoln used to emphasize that everyone has a stake in the war is C. PARALLEL STRUCTURE.

He compared the expectations and desires of both parties using the parallel structure to show that the concerns were of the same level of importance.
