Which of the following strategies is unique to reading narrative texts?

Understanding character motivations is a strategy that specifically enhances the reading of narrative texts. Narratives, by their nature, involve characters, plots, and emotional arcs. Recognizing and analyzing the motivations behind a character's actions helps readers to engage more deeply with the story and to understand the underlying themes and emotional context. This understanding can influence how readers interpret events within the plot, perceive the development of characters, and appreciate the author’s intent.

While summarizing key facts and identifying main ideas are important reading strategies, they are not unique to narrative texts since they apply to various kinds of texts, including informational and persuasive genres. Analyzing data sources is primarily linked to expository texts or research materials, making it less relevant in the context of narrative reading. Therefore, focusing on character motivations provides a richer and more nuanced understanding of narratives, which distinguishes this strategy in the context of literary analysis.
