Answer:
I think Equiano uses very descriptive language to keep the reader entertained and hooked. Equiano makes use of describing words and metaphors to paint a picture in the reader's head so they can visualize what's happening in the text. We see this throughout the text where he says, "clouds appeared to me to be land" and when how he describes the fishes as " flying." Time and time again Equiano describes what he sees and where he's at so that the readers have a clear understanding. Equiano compels the reader to keep reading through his vivid descriptions and curiosity of scenarios in the text.
It also reminds us that Equiano was still a child at the time of his capture and transport, making all of the other incidents described in the text seem that much more horrifying.
