Final answer:
In 'To Kill a Mockingbird,' Mr. Ewell uses racial prejudices to convince the jury to convict Tom Robinson, relying on stereotypes rather than evidence.
Step-by-step explanation:
In Harper Lee's To Kill a Mockingbird, Mr. Ewell relies on the racial prejudices and stereotypes of the time to sway the jury to convict Tom Robinson. These "facts about Negroes" are not actual facts but rather deeply ingrained racist beliefs that African Americans were somehow inferior and untrustworthy. Such distorted views were intended to make the jury distrust Tom's testimony and see him as guilty despite the lack of concrete evidence against him. The novel clearly showcases how race and racism can influence the outcome of legal proceedings, highlighting the injustices that can occur within a biased judicial system.
