Read the following passage and answer the question that follows:
In the world of literature, the quest for realism often leads authors to implement various techniques to create authentic narratives. For instance, many contemporary writers use stream-of-consciousness to illustrate a character's thoughts in real time, which offers an immediate insight into their psyche. Others may opt for unreliable narrators, creating a layer of complexity that prompts readers to question the truth of the narrative being presented. Additionally, nonlinear timelines challenge readers to engage actively with the text as they piece together the events of the story. These approaches not only enhance the depth of character development but also invite readers to contemplate broader themes within the work.
