Task: Question Generation
Input (English): Passage: In London, Lady Margaret Windermere is busy discouraging Lord Darlington's flirting, while her husband receives a letter from Edith Erlynne, "a complete stranger," asking to meet him on a urgent matter. A woman of great beauty but terrible reputation, she reveals that she is the mother of Lady Windermere, who believes she is dead and reveres her memory. Fearing that his wife would be crushed by the truth and seeing a pile of bills on Mrs. Erlynne's desk, Lord Windermere gives her a cheque for ₤1500 for her silence.
Mrs. Erlynne resumes her scandalous lifestyle. At a horse race, she attracts the attention of many, including members of the Windermere party, notably Lord Augustus Lorton, "London's most distinguished bachelor," and three snoopy, gossipy women. As Lord Windermere defends Mrs. Erlynne to the latter, his wife becomes a bit concerned. Mrs. Erlynne leaves. Lorton follows and is soon calling on her regularly.
For Lady Windermere's birthday, her husband gives her jewelry and a lovely fan. When he leaves the mansion, she and Darlington by chance see him dismiss his chauffeur and take a taxi instead. Darlington then tells her that Mrs. Erlynne's name may be found in her husband's cheque book and declares his love for her. Meanwhile, Mrs. Erlynne blackmails Lord Windermere into an invitation to a ball that night, explaining that such "social recognition" might help elicit a marriage proposal from Lord Lorton. When he returns home, his wife confronts him with his copy of the ₤1500 cheque, which she found after breaking into his locked desk drawer. He tells her he only helped a deserving woman in need, but she becomes further infuriated when he informs her that Mrs. Erlynne will be coming to their ball that night.
Output (English): What is the last name of the person whose wife becomes a bit concerned?
