He makes the novel believable.

Explanation:

Mark Twain's children novel The Adventures of Huckleberry Finn tells the coming-of-age story of the protagonist Huck Finn whose main aim is to go on adventures and not be made to study or obey societal rules. He 'escapes' and went on an adventure, searching for freedom and going to places he had never been on a raft with Jim and some other men he met along the way.

The author of the story uses the dialogue form as well as the narration form for the whole storytelling process. This allows for the story to be more believable, providing a sense of realistic features in the dialogue between the characters while at the same time allowing a sort of storytelling feature though the narration method.
