Final answer:
Atticus' stomachache likely symbolizes his internal conflict or moral dilemma during questioning Mayella, reflecting his commitment to justice and truth.
Step-by-step explanation:
The character Atticus in literature often portrays a figure of moral integrity and stoic calmness, particularly in the context of a courtroom drama. When Atticus appears to have a stomachache or discomfort after questioning Mayella, it may suggest internal conflict or a moral dilemma. In literature, physical symptoms can symbolize emotional or psychological stress. Atticus, being a character committed to justice and truth, might be distressed by the revelations or the resistance during the questioning, which can manifest as physical discomfort. Authors often use descriptions of a character's physical state to hint at their deeper feelings, so Atticus' apparent stomach pain could be an indication of his unease with the situation or his empathy for the witness who is under pressure.
