Final answer:
The information provided does not indicate that Lucy claims anyone runs the Christmas racket; the excerpt mentions a personal anecdote about Santa Claus and Nora's concerns during Christmas, but no mention of Lucy or a racket.
Step-by-step explanation:
In the context of the information provided, it does not appear that Lucy claims anyone in particular runs the Christmas racket. The excerpt from LibreTexts discusses a personal anecdote about believing in Santa Claus during Christmas and does not mention Lucy making a claim about who runs the Christmas racket. The reference to Nora, who is concerned about a potential problem during the Christmas holidays and is relieved that no one has come to her door and that there are no letters in her letterbox, does not include any statements about Lucy or a so-called Christmas racket. It appears there may be a mix-up with the text references or the question itself.
