Which of the following best describes the purpose of theme in literature?

The purpose of theme in literature is best described by the idea that it allows for judgments on characters and actions. Theme refers to the underlying message or central idea that a literary work conveys, which often leads readers to reflect on moral questions or broader social issues. This thematic exploration can reveal insights into characters’ motivations, the consequences of their choices, and the ethical dilemmas they face, ultimately prompting readers to form judgments about the characters and their actions within the narrative context.

While the other options relate to important aspects of literature, they do not encapsulate the central role that theme plays in shaping our understanding of characters and moral questions. Rhyme schemes pertain more to poetry and sound patterns, while mood relates to the emotional atmosphere of a piece rather than its thematic elements. Additionally, narrative structure concerns the organization of the story rather than the thematic insights derived from it. Thus, the choice encapsulates how themes serve to provide a critical lens through which readers assess characters and their decisions.
