Which passage from “An Upheaval” interrupts the narrative to reveal an important aspect of Mashenka’s character?

An Upheaval

A) Mashenka, amazed and frightened, went on packing; she snatched her things, crumpled them up, and thrust them anyhow into the box and the basket. Now, after this candid avowal on the part of Nikolay Sergeitch, she could not remain another minute, and could not understand how she could have gone on living in the house before.

B) Mashenka brushed her hair, wiped her face with a wet towel, and went into the dining-room. There they had already begun dinner. At one end of the table sat Fedosya Vassilyevna with a stupid, solemn, serious face; at the other end Nikolay Sergeitch. At the sides there were the visitors and the children. The dishes were handed by two footmen in swallowtails and white gloves.

C) Mashenka looked round her room with wondering eyes, and, unable to understand it, not knowing what to think, shrugged her shoulders, and turned cold with dismay. What had Fedosya Vassilyevna been looking for in her work-bag? If she really had, as she said, caught her sleeve in it and upset everything, why had Nikolay Sergeitch dashed out of her room so excited and red in the face? Why was one drawer of the table pulled out a little way?

D) Mashenka remembered that under the sheets in her basket she had some sweetmeats, which, following the habits of her schooldays, she had put in her pocket at dinner and carried off to her room. She felt hot all over, and was ashamed at the thought that her little secret was known to the lady of the house; and all this terror, shame, resentment, brought on an attack of palpitation of the heart.
