Read the passage from Shakespeare's Macbeth and answer the question that follows: "Will all great Neptune's ocean wash this blood Clean from my hand? No, this my hand will rather The multitudinous seas in incarnadine, Making the green one red." Why does the speaker mention Neptune, the Roman god of the sea? To contrast the power of a god with the blood on his hand
To contrast the power of Neptune with that of the Christian god
To invoke Neptune to save him from his guilt
To praise Neptune for his mercy on a murderer
