How does Gulliver obtain ropes, sails, and an anchor for his boat?

Gulliver obtains ropes, sails, and an anchor for his boat by making them with help from the Lilliputians. This collaboration showcases the resourcefulness and ingenuity of both Gulliver and the tiny inhabitants of Lilliput. It highlights the theme of cooperation and mutual assistance, where Gulliver utilizes the materials available to him with the assistance of the Lilliputians, who are eager to help him. This process not only emphasizes the bond formed between Gulliver and the Lilliputians but also his adaptability in a foreign environment, reinforcing the narrative's exploration of cultural exchange and teamwork.

The other options do not accurately portray the sequence of events in the story. For instance, Gulliver does not simply purchase these items from merchants, nor does he find them washed up on the shore. Additionally, receiving them as gifts would imply a more passive role for Gulliver, which contrasts with his active involvement in creating these items with the help of the Lilliputians.
