What does Gulliver do after leaving Lilliput?

After leaving Lilliput, Gulliver continues his adventures as a voyager, ultimately seeking new experiences and discoveries in unexplored lands. This aligns with his character as an adventurous and curious individual dedicated to exploring the world. The narrative portrays Gulliver's longing for exploration and knowledge, suggesting that he is more compelled by the spirit of adventure than by settling down in any one place, such as Lilliput. His experiences in Lilliput serve as a catalyst for further journeys rather than a conclusion to his travels.

The other options suggest alternatives to Gulliver's exploratory nature. Settling permanently in Lilliput would contradict his desire for adventure, while returning to England to become a politician limits his character's narrative focus on exploration. Additionally, becoming a mentor implies a long-term commitment to the Lilliputians, which does not align with Gulliver's trajectory as he seeks to move on to new adventures. Thus, his decision to become a successful voyager again is the most fitting continuation of his character's journey.
