Final answer:
Jem's refusal to brag about his father symbolizes his pride and confidence in his father's intrinsic worth over superficial accomplishments.
Step-by-step explanation:
When Jem says he does not have to brag about his father, it shows a sense of pride and confidence in his father's moral character and abilities. This sentiment may also reflect a broader understanding of the themes present in the text, such as dignity, integrity, and the subtleties of social standing. The characters in these various excerpts often grapple with their identity, whether through wealth, status, or virtue, and Jem's statement may echo these broader narrative concerns where deep respect for intrinsic values takes precedence over external achievements.
