Final answer:
The most significant reason for explaining events before quoting is to give the quote context, ensuring readers understand its relevance and implications in the story.
Step-by-step explanation:
The most important reason that the writer explains what's happening in the story before giving the quote is B: It gives the quote context, so the reader understands what was happening at the time of the quote. Explaining the circumstances that precede a quote helps readers grasp the quote's significance and how it fits into the narrative. For instance, knowing that Buck in The Call of the Wild is unaware of the impending trouble due to a gold rush enhances the understanding of his predicament. Similarly, insight into Mrs. Bennet's character in Austen's novel through narration rather than internal monologue shows instead of tells the reader about her nature. Thus, framing a quote with adequate context is crucial for readers to correctly interpret the significance and implications of what is being quoted.
