Definition: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Input: Which of the following is not a character in the novel: Christopher Metress, Boo Radley or Tom Robinson?, Context: Tom Robinson is the chief example among several innocents destroyed carelessly or deliberately throughout the novel. However, scholar Christopher Metress connects the mockingbird to Boo Radley: "Instead of wanting to exploit Boo for her own fun (as she does in the beginning of the novel by putting on gothic plays about his history), Scout comes to see him as a 'mockingbird'—that is, as someone with an inner goodness that must be cherished." The last pages of the book illustrate this as Scout relates the moral of a story Atticus has been reading to her, and in allusions to both Boo Radley and Tom Robinson states about a character who was misunderstood, "when they finally saw him, why he hadn't done any of those things ... Atticus, he was real nice," to which he responds, "Most people are, Scout, when you finally see them."
Output:
Christopher Metress
