I need some help with this question on Shakespeare's "Macbeth." Just a basic answer would be best, I can elaborate. Choose an event from the play. Focus on the purpose it serves in the story. Consider how the story would change if that event was altered. Form your ideas into a paragraph of at least five sentences. Make sure to include supporting evidence from the play.

Some events to consider:

The weird sisters' predictions for Macbeth and Banquo
Macbeth's murder of Banquo
The appearance of Banquo's ghost at Macbeth's coronation dinner

Your answer must cite directly from the lines of Macbeth that you read in the lesson.
