What is the fate of Gulliver at the end of "Gulliver's Travels"?

At the end of "Gulliver's Travels," Gulliver's choice of solitude reflects his disillusionment with humanity after his experiences in various fantastical societies. Having encountered different cultures, from the tiny Lilliputians to the noble Houyhnhnms and the uncivilized Yahoos, he becomes increasingly alienated from the ways of his own society. This alienation leads him to feel that he cannot connect with or relate to the people of his homeland, prompting him to seek isolation rather than to engage with others.

The other options highlight alternatives that Gulliver does not pursue. He does not find a new society that meets his ideals; instead, he becomes critical of all human societies. While he does return to his homeland after his travels, it is not accompanied by a sense of belonging or contentment, thus, it does not define his ultimate fate. Additionally, he does not attain a position of power or leadership, as he becomes more of a recluse than a ruler.
