Task: Question Generation
Input (English): Unable to find work in London at the height of World War I, American chorus girl Myra Deauville resorts to prostitution to support herself. She meets her clients on Waterloo Bridge, the primary entry point into the city for soldiers on leave. During an air raid, she meets fellow American Roy Cronin, a member of the Canadian Army, and he joins Myra in her apartment.Describing herself simply as an unemployed chorus girl, Myra gains Roy's sympathy, and he offers to pay her overdue rent. After she rejects his offer and he departs, Myra returns to the streets. The following morning, Roy returns to visit her, and landlady Mrs. Hobley lets him into her apartment. There he meets Myra's friend and neighbor Kitty, who tells him Myra needs someone to love and protect her. Myra later berates Kitty for interfering and rejects her advice to marry Roy to ensure a better future for herself.Roy brings Myra to visit his mother Mary and sister Janet at their country estate, where he proposes to Myra, who later that night tells Mary the truth about herself. Mary is sympathetic but implores Myra not to marry Roy. The following morning, Myra slips away and returns to London by train. Eventually Roy visits her and asks her to explain her abrupt departure. Because he is on the verge of returning to the battlefields in France, he begs Myra to marry him immediately. She agrees, but escapes from her apartment through a window while he waits for her in the hallway. Seeking the rent, Mrs. Hobley enters and, believing Myra has run off to avoid her financial obligation, reveals her true profession to Roy.Although shocked, Roy searches for Myra and eventually finds her on Waterloo Bridge, where he tells her he still loves and wants to marry her. The military police insist Roy join a truck of departing soldiers or be considered a deserter, and once he secures Myra's promises to marry him upon his return, he departs. The air raid sirens sound, and as Myra seeks shelter, she is killed by a bomb.
Output (English): Question: Who is Roy's mother?, Answer: Lady Margaret.
