What specific narrative technique is commonly employed by the author in the passage to convey information?

In the context of narrative techniques, using biographical sketches allows an author to weave personal history and experiences into the narrative. This technique enriches the story by providing deeper insight into a character’s motivations, background, and development, thus enhancing the reader's connection to the narrative. Biographical sketches can facilitate a strong emotional resonance, as they present characters not just as figures in a plot but as real individuals with complex lives that influence their actions and decisions.

This is particularly effective when the passage aims to provide context or an understanding of the themes through the characters' pasts. By utilizing this narrative method, the author effectively conveys critical information that shapes the reader’s comprehension of the storyline and characters, ultimately contributing to a more engaging and comprehensive narrative experience.
