A personal story featured on an individual's blog
The anwser is A: That like Polybus, the prophecy is dead and buried.
By saying that the prophetic oracles were worthless, the speaker demonstrates his complete dislike and disregard for them. And to emphasize his opinion, he adds that Polybus has taken them to Hades (in older Greek mhyts this the abode of the dead,where all mortals go when they die), which is a place where he already is.
Answer: It reveals Ahab’s commitment to his mission for revenge.
In this passage, the speaker is describing the impact that Ahab caused when meeting him for the first time. He describes his white, whalebone leg, and how he fashioned it out of a sperm whale's jaw. He also describes how there was an auger hole on the deck, upon which Ahab would steady his leg. He would stand there and look out beyond the prow for hours on end. The speaker also describes his attitude of determination and wilfullness. All of these elements contribute to showing how commited Ahab was to his mission.
