Final answer:
Telling '50 years gone by' from an adult child's point of view would likely mean the reader misses out on the backstory of the dress and the route, as the adult child may not know these details (option a). This perspective shift could affect the depth of storytelling compared to an omniscient narrator.
Step-by-step explanation:
When a story is told entirely from an adult child's point of view, the narrative would likely shift significantly in content and perspective. If '50 years gone by' were told from this viewpoint, option (a) seems most plausible: the reader wouldn't know the story behind the dress, the route. This is because the adult child might not have access to the entire backstory or the memories of Esteli and Charlieee, which could be unknown or lost to them. Consequently, the details that would typically be provided by an omniscient or all-knowing narrator would be absent. The narrator's limited understanding may also impact the depth of emotional insights into Esteli and Charlieee, although this is not specifically mentioned in the options provided.
Stories told from a first-person perspective are colored by the narrator's personal biases, experiences, and level of knowledge. An adult child's point of view would offer a different take on Esteli and Charlieee's relationship than either of the characters would themselves. This would significantly shape the reader's experience, potentially omitting key historical, cultural, or emotional contexts that an omniscient narrator or even one of the characters might have provided.
