Read this excerpt from Infinite Jest.I cannot make myself understood. ‘I am not just a jock,’ I say slowly. Distinctly. ‘My transcript for the last year might have been dickied a bit, maybe, but that was to get me over a rough spot. The grades prior to that are de moi.’ My eyes are closed; the room is silent.How does the narration affect the narrator’s credibility in this excerpt?

The narrator quickly qualifies his academic record, admitting that his transcript may have been altered but insisting that his earlier grades were genuinely his. That defensive explanation makes him seem concerned with justifying himself, which can weaken his credibility. The best choice is “His explanations depict him as a bit defensive.”
