Step-by-step explanation:
The student's question pertains to the character Mrs. Birling from the play “An Inspector Calls”. However, the references provided are mixed and pertain to different literary works and characters, such as Mrs. Linde from Henrik Ibsen's “A Doll's House” and scenes from other unrelated texts.
