Final answer:
The word 'medium' most nearly means 'The way in which a piece of writing is delivered', reflecting the method an author uses to convey their story to the audience.
Step-by-step explanation:
The word medium most nearly means 'The way in which a piece of writing is delivered'. This is especially relevant in the context of creative nonfiction, which includes personal narratives and memoirs. The medium refers to the method or manner an author chooses to convey their story, which could be through various forms of media, such as print, broadcast, or social media. The chosen medium plays a crucial role in how the story is experienced by the audience, influencing the level of emotional engagement and the overall impact of the narrative.
Comparatively, while 'a story of a person's life or experiences written by another person' describes a biography, and 'tells a story based on facts' can be associated with creative nonfiction, neither of these options captures the definition of medium as well as 'the way in which a piece of writing is delivered'. Also, 'break it down into parts, tell about the parts' pertains more to the analysis of a text, rather than its medium.
