The supernatural plays a large role in Macbeth. Had the witches not talked to Macbeth in the beginning of the play & told him of what he could become, none of the events that followed would have taken place. This gives an overall dark mood to the story. The mood relates to the play's central conflicts because after talking to some really dark and evil beings, Macbeth does some dark and evil things.
I would say that all of them are answers to the question
