Answer:
It pains Miss Darcy to hear because it reminds her of the previous attachment between her brother, Mr. Darcy, and Miss Elizabeth Bennet
Step-by-step explanation:
The ——shire Militia was stationed in Meryton, where the Bennet family resides. Mr. Darcy had previously shown an interest in Miss Elizabeth, and his involvement with the militia, particularly their social events and gatherings, provided opportunities for them to interact. However, due to Miss Bingley's remark, it becomes evident that Mr. Darcy's absence from Meryton will decrease the chances of future encounters between him and Miss Elizabeth.
Miss Darcy is aware of her brother's feelings for Miss Elizabeth and the positive changes she has observed in him since meeting her. The removal of the militia, which indirectly separates Mr. Darcy and Miss Elizabeth, brings disappointment and pain to Miss Darcy because she knows that the potential for their relationship to develop further is hindered.
It is important to note that this interpretation is based on the context of Jane Austen's Pride and Prejudice. The novel explores themes of societal expectations, love, and misunderstandings, and the relationship between Mr. Darcy and Miss Elizabeth is a central focus of the story.
