How do the Lilliputians manage to move Gulliver?

The correct choice highlights the ingenuity of the Lilliputians in their efforts to manage Gulliver's enormous size relative to their own. They create special machines that enable them to move large objects, akin to trees, thus demonstrating their technological capabilities despite their small stature. This showcases the theme of practicality and resourcefulness, as the Lilliputians adapt to their circumstances by engineering solutions to their challenges.

The other options, while they may suggest alternative methods of control or manipulation, do not accurately reflect the narrative of how Gulliver is handled. For instance, option A implies deceit, which oversimplifies the interaction between Gulliver and the Lilliputians and undermines their cleverness. Similarly, option B suggests a reliance on magical solutions rather than innovative engineering, which is contrary to the satirical portrayal of human ingenuity in the text. Lastly, option D involves persuasion, but given Gulliver's overwhelming size, it would be impractical for the Lilliputians to use mere words to influence him to move as they would wish. Therefore, the answer focuses on their mechanical prowess instead.
