Final answer:
Scout overhears Miss Gates expressing racist sentiments, saying that black people were 'gettin' way above themselves' and suggesting it's time they were taught a lesson.
Step-by-step explanation:
Scout overhears Miss Gates speaking to Stephanie Crawford on the night of Tom Robinson's trial. Scout recounts hearing Miss Gates's words which reflect a racist attitude and hypocrisy. Scout is puzzled by the contradiction between Miss Gates's condemnation of Hitler's actions against the Jews and her racist comments towards the black community in her own town. The specific phrases Scout hears Miss Gates say are: 'It's time somebody taught 'em a lesson, they were gettin' way above themselves' and 'The next thing they think they can do is marry us'. These remarks highlight the ingrained racial prejudices of the time, and they disturb Scout, who reports this instance to her brother, Jem.
