How does Gulliver escape from the floating island of Laputa?

Gulliver's escape from the floating island of Laputa is facilitated by his use of knowledge and negotiation skills. Throughout his journey, Gulliver discovers that the inhabitants of Laputa are obsessed with abstract science and mathematics, often to the detriment of practical matters. By demonstrating intelligence and presenting himself as a useful asset, he engages with the Laputans, who often overlook practical solutions in favor of theoretical concepts.

Through shrewd negotiation and understanding of their needs and quirks, Gulliver effectively convinces them to let him go. This reflects the broader themes in Jonathan Swift's work, where intelligence, reason, and negotiation are depicted as powerful tools to influence those in positions of authority.

The other options do not accurately capture the essence of Gulliver's escape. He does not simply steal a ship or find a secret passage, nor does he rely solely on the assistance of the king to leave Laputa, demonstrating a more complex interaction driven by his own wits and knowledge.
