Final answer:
The author develops Louisa's point of view mainly by describing her internal reactions and considerations in response to changes around her, particularly the success of Joe Dagget, her fiance, and their upcoming marriage.
Step-by-step explanation:
The MAIN way in which the author develops Louisa's point of view is by describing how she responds to his success. From the provided excerpts, we can deduce that Louisa's fiance, Joe Dagget's success, and changes to his and Louisa's life are focal points of her perspective.
The author uses third-person narration to convey Louisa's inner contemplations, her hesitations, and her eventual decisions which stem from her response to the transformations happening around her, particularly Joe's success and the impending marriage. The writer also employs vivid details to highlight the nuances of Louisa's character and emotions. A key moment that encapsulates this development is when Louisa meditates by her window, reflecting on her life and future after overhearing a conversation that reveals Joe's true feelings. This indirect characterization allows readers to infer Louisa's feelings and thoughts without directly being told by the author.
