Final answer:
Scrooge's preference for sleep over the spirit's help exemplifies indirect characterization.
Step-by-step explanation:
The type of characterization that Scrooge's preference for sleep over the spirit's help exemplifies is indirect characterization. Indirect characterization is when the author reveals a character's traits through their thoughts, actions, and dialogue, rather than directly stating them. In this case, Scrooge's choice to prioritize sleep over the spirit's assistance shows his stubbornness, selfishness, and resistance to change. Through this action, the reader can infer and understand Scrooge's character.
