The purpose of the quote is to emphasize Scrooge's desire to keep people out of his life, highlighting his reclusive nature and aversion to social interaction. Option C is correct.
The quoted passage from paragraph 87 serves to underscore Ebenezer Scrooge's reclusive and solitary nature. Charles Dickens, in "A Christmas Carol," employs this description to illuminate Scrooge's intense desire for isolation and his aversion to social interaction. The act of closing and double-locking his door symbolizes not just a physical barrier but a psychological one, reflecting Scrooge's commitment to maintaining distance from the world outside.
The repetition of the phrase "which was not his custom" heightens the significance of this action. It suggests a departure from ordinary behavior, emphasizing that Scrooge's isolation goes beyond mere personal preference—it is an ingrained aspect of his character. This deliberate choice to isolate himself provides insight into Scrooge's mindset, hinting at deeper issues that may contribute to his miserly and cold-hearted demeanor.
While the option to convey fear and dread may be relevant in other contexts, the primary purpose in this instance is to convey Scrooge's inclination to keep people at bay, reflecting his detachment from the warmth of human connection. This emphasis sets the stage for the transformative journey that Scrooge is about to embark on, ultimately highlighting the contrast between his initial isolation and the eventual opening of his heart to others.
