What fresh problem now disturbs Mme Loisel?
The fresh problem that now disturbs Mme Loisel is the lack of jewellery to wear with her new dress for the upcoming ball. Even though her dress is nearly ready, she feels sad, disturbed, and anxious because she has nothing to adorn herself with.
She tells her husband that without any jewels, she will have a poverty-stricken look. She is so vexed by this issue that she declares she would prefer not to go to the party at all rather than attend looking poor and unadorned.
Explanation
The textbook context clearly mentions that after her dress is nearly ready, Mme Loisel seems sad and disturbed. When her husband asks the reason, she expresses her vexation at not having a jewel to adorn herself with, fearing a poverty-stricken look. This forms the 'fresh problem' after the initial problem of getting a dress is solved.
