Step-by-step explanation:
The student has inquired about how Kalypso reacts to Zeus' orders in Book 5 of 'The Odyssey'. To answer this, Kalypso receives Zeus' orders via Hermes, who tells her that she must let Odysseus go. Initially, Kalypso is heartbroken and reluctant as she is deeply in love with Odysseus and had hoped to keep him on her island forever. Despite her own desires, she ultimately submits to Zeus' command, showing both her deference to the king of the gods and the inevitable nature of divine will over mortal and lesser divine desires. Kalypso aids Odysseus in building a raft and provides him with supplies for his journey, though her heart aches at his departure.
