In the context of literature, what does the term "artificial" imply about the format of letters in 20th-century novels?

In the context of literature, the term "artificial" when applied to the format of letters in 20th-century novels implies that these letters may feel contrived or disconnected from genuine human experience. This suggests that they do not authentically capture the spontaneity and emotional depth characteristic of real letters written in personal correspondence.

The use of letters in novels can sometimes be more about serving the narrative or thematic needs of the story rather than reflecting true feelings or spontaneous communication. As a result, they can appear outdated or less relevant to modern readers who may not identify with the conventions and styles of earlier periods, including the constraints and manners typically associated with letter writing.

While other options indicate various positive aspects, they do not align with the notion of “artificiality.” The focus on a perceived lack of authenticity is key to understanding why the implication of being "outdated" fits well with the concept of artificiality in this context.
