Final answer:
Abraham Lincoln's use of parallel structure in his Second inaugural address emphasizes the importance of unity.
Step-by-step explanation:
Abraham Lincoln's use of parallel structure in his passage from the Second inaugural address emphasizes the importance of unity.
By repeating the structure 'with...with...with' in the opening sentence, Lincoln highlights the idea of treating others with malice toward none and charity for all. This parallelism reinforces the notion of coming together as a nation, putting aside differences and working towards a just and lasting peace.
Therefore, the correct answer is B. It stresses the importance of unity.
