Task: Question Generation
Input (English): Passage: Wealthy American businessman Robert Talbot owns a villa on the Ligurian coast, where he and his Roman mistress Lisa Fellini spend September of each year. When Robert moves up his annual visit to July and calls her en route from Milano, she cancels her wedding to Englishman Spencer and rushes to meet him. Upon his arrival at the villa, Robert discovers that, in his absence, his major domo, Maurice Clavell, has turned the villa into a hotel, currently hosting a group of teenage girls, including Sandy, and their chaperone, Margaret Allison. Their departure is delayed when Margaret slips on the cork of a champagne bottle opened by Robert and is forced to spend a day in the hospital. Four teenage boys who irritated Robert on the drive to his villa, including Tony, set up camp right outside of the villa and begin courting the girls.
Robert chaperones the girls on a sightseeing tour and to a music club. He dances with each of the girls and appeals to their virtues, stressing the importance of chastity. Trying to get Robert inebriated, the boys end up drunk themselves. Sandy revives Tony, but slaps him when he makes a pass at her. She then recounts the lecture received earlier to Lisa, who gets infuriated over Robert's double standards. The next morning, she leaves to get back together with Spencer. A sobered-up Tony apologizes to Robert.
Output (English): What is the full name of the person who cancels their wedding?
