An "End Rhyme" is what you are referring to, I believe. Hope this helps!
Answer:
B. to lend impact to the sonnet's conclusion.
Explanation:
The lines present in the question were taken from Shakespeare's Sonnet 130. <u>The two lines at the end, or the final couplet, are structured in a different way from the others because their purpose is to lend impact to the sonnet's conclusion. Throughout the poem, the speaker is "criticizing" the woman he loves. </u>While Petrarchan sonnets were usually used to elevate women to an impossible status, comparing them to natural elements and concluding that they were always more beautiful, Shakespeare's Sonnet 130 does the opposite. The woman is a normal one, not more beautiful, sweeter, nor better smelling than anything else. <u>Still, at the final couplet, after all that criticism, the speaker says he loves her. Not only does he love her, but he won't lie about her. He loves her for who she really is.</u>
I find all of the answers pretty neutral (that is, giving only facts, no judgements) except on sentence 3: this is because of the word "sharply".
It seems that the author of this sentence makes a judgement about the split: that they're very split, that their argument was very intense. It seems like a judgement to me more than the other sentences.
I do it is possible,if you believe something but the other side of the argument has more evidence or logically make more sense, you would still argue because it is your opinion and your belief, therefor you would want to explain it.
