The protagonist's main purpose is to be able to express herself as an American, due to the fact that she now lives in the United States. We learn that she is very happy to be able to express herself properly in this way when she says: "When I was done, I read over my words, and my eyes filled. I finally sounded like myself in English!" However, the protagonist also wants us to learn how her family's past has impacted their views, and the deep connection that she feels with her mother. This is obvious when the protagonists says that her mother tried to make her feel better after her fight with her father. We also learn that her mother was very supportive:
"“Go away,” I wailed, but we both knew I was glad she was there, and I needed only a moment’s protest to save face before opening that door.
I believe it is A due to "The lady made detailed plans, engaged the caterer and the orchestra well in advance" isn't exactly connect well and be hard to understand so you'd put a comma between "caterer, and".
