Answer:
**(a) Compare and Contrast:**
In Scene II of Macbeth, both Macbeth's and Banquo's reactions to the witches' prophesies share similarities and differences. Similarities may include initial astonishment and curiosity about the supernatural revelations. However, differences emerge in their emotional responses and subsequent actions.
**(b) Make Inferences:**
Macbeth's reaction implies a deep-seated ambition and susceptibility to the allure of power. His immediate consideration of the witches' prophecies reveals an internal conflict and foreshadows his descent into corruption. On the other hand, Banquo's more cautious response suggests a skepticism or moral restraint, hinting at his nobler character and resistance to the temptations that lead Macbeth astray.
