Final answer:
Stephanie Crawford says that Mr. Ewell saw Tom Robinson's death as an opportunity for revenge, particularly against those he saw as his enemies.

Mr. Ewell viewed Tom's death as an opportunity to seek revenge on other people he considered his enemies, indicating option 3, Tom's death made Ewell seek revenge on two or more people, as the correct answer to the student's question. Bob Ewell felt empowered by the acquittal and Tom's subsequent death, and he made threats against others, most notably those involved in the trial who had opposed him.
