Final answer:
Macbeth's response to the prophecy shows his hidden ambition and consideration of fate's role in his advancement, suggesting a possible desire for power. Banquo, on the other hand, responds with caution and skepticism, questioning the reality of the witches' words and highlighting his rational approach.
Step-by-step explanation:
Macbeth's and Banquo's responses to the prophecy reveal significant differences in their characters. Macbeth's reaction shows a hidden desire for power and advancement. In the excerpt, Macbeth's aside, "If chance will have me, king, why, chance may crown me, Without my stir," indicates he is intrigued by the idea of becoming king and is considering the role that fate may play in achieving this position. This contemplation suggests ambition and a willingness to entertain the prophecy's potential.
In contrast, Banquo is more cautious and skeptical about the prophecy. His lines, "Were such things here as we do speak about? Or have we eaten on the insane root," highlight his skepticism and inclination to question the reality of the witches' words, as opposed to blindly accepting them. Banquo's concerns imply a level-headedness and a more rational approach to the supernatural event.
Overall, Macbeth's reaction to the prophecy is one of curiosity and latent ambition, while Banquo's is characterized by wariness and skepticism. These differing responses foreshadow the paths each character will take as the story unfolds, with Macbeth becoming ensnared by his ambition and Banquo remaining wary of the witches' predictions.
