What does the title of a significant chapter refer to?

The choice indicating that the title of a significant chapter refers to a song that Henry used to sing is correct because music plays a notable role in Bryan Stevenson's narrative about the lives of those he represents. In "Just Mercy," Stevenson often uses personal anecdotes and stories to illustrate the human experiences behind the legal cases. The song sung by Henry reflects themes of hope and resilience, resonating with the struggles and injustices faced by individuals within the prison system. This connection to music serves to deepen the emotional impact of the chapter, highlighting the importance of personal narratives and cultural expressions in understanding the broader issues of justice and mercy.

The other options do not align as closely with the overarching themes and personal touch that Stevenson infuses into his work. While Henry may have told a story or inspired Bryan with a poem, the specific choice of a song captures the essence of the emotional and cultural landscape that Stevenson aims to portray. Similarly, while legal cases are central to the narrative, the song emphasizes the personal and human elements that Stevenson seeks to highlight throughout his discussions of justice.
