Final answer:
Atticus appears confident in his method of cross-examining Mayella, showing patience and compassion while questioning her in a calm and polite manner.
Step-by-step explanation:
Atticus appears to feel confident about his method of cross-examining Mayella in the novel To Kill a Mockingbird by Harper Lee. He believes that there is only one way of proving one's faith in a just cause, which is through thorough and intense questioning. Atticus shows compassion and patience during the cross-examination, aiming to reveal the truth rather than attacking Mayella personally.
Atticus's approach can be seen in his questioning style, where he calmly and politely asks Mayella to clarify her statements. For example, when she accuses Tom Robinson of beating her, Atticus asks her to demonstrate how he could have done so with his crippled arm.
Overall, Atticus's demeanor during the cross-examination suggests that he is confident in his method and believes in the importance of fairness and justice.
