The answer to this question is B.
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.
Answer:
Postponing the plot in order to focus on Theseus.
Explanation:
Suspense is a feeling of intensity a reader experiences while anticipating an intrigue's outcome. Authors have different ways of creating suspense whose objective is to <em>awake interest</em> and <em>encourage further lecture</em>.
In this particular excerpt, the delay in events is produced by a sudden <em>episode</em> on Theseus, an important character whose story <em>slows down the denouement of the main story.</em>
