Task: Question Generation
Input (English): Passage: While driving his Dual-Ghia from Las Vegas to Los Angeles, lecherous, heavy-drinking pop singer Dino is forced to detour through Climax, Nevada. There he meets the amateur songwriting team of Barney Millsap, a gas station attendant, and piano teacher Orville J. Spooner, a man easily given to jealousy. Hoping to interest Dino in their songs, Barney disables the "Italian" sports car and tells Dino he will need to remain in town until new parts arrive from Milan. (Dual-Ghia was actually an American marque, mating a Dodge frame, drivetrain, and engine with Italian coachwork.)
Orville invites Dino to stay with him and wife Zelda, but becomes concerned when he learns the singer needs to have sex every night to avoid awakening with a headache. Anxious to accommodate Dino but safeguard his marriage, Orville provokes an argument with his wife that leads to Zelda fleeing in tears. He and Barney then arrange for Polly the Pistol, a waitress and prostitute at a saloon on the edge of town called the Belly Button, to pose as Orville's wife and satisfy Dino.
That evening after the three have dinner, Orville plays his tunes for Dino on the piano and Polly requests a particular song. It is one she knows he wrote for his wife when trying to persuade her to marry him. Doing so, Orville gets lost in emotion, as does Polly, who has fallen a little for the dream of a domestic life that she doesn't have. Under the influence of wine and song, Orville starts thinking of Polly as his wife and tosses Dino out. He then spends the night with Polly.
Output (English): What are the real names of the three people who have dinner?
