input question: Generate a question that has the following answer: Ben for the following movie plot: Dr. Benjamin Stone is a promising young surgeon working in Washington, D.C. with plans of making more money working for a Beverly Hills plastic surgeon. On his last day, he realizes that none of his colleagues care enough about him to say good-bye to him, instead leaving him a cake with an insult made out of icing. Driving out west in a 1956 Porsche 356 Speedster, Stone swerves to miss a cow on the highway and crashes uncontrollably into the fence of a local resident in the rural hamlet of Grady, South Carolina. The resident is local Judge Evans, who sentences him to community service at the nearby hospital as punishment rather than allow Stone pay for the fence with cash. Defeated and stranded due to the damage to his car, Ben reports to the local clinic, where Nurse Packer further humbles him by recording his community service hours by clocking him in and out, like a factory worker. Though upset, Ben makes friends with Mayor Nick Nicholson, who is also the owner of the town's cafe, and Melvin, the local mechanic tasked with repairing his car. Ben soon finds the clinic work is more laid-back than the emergency room to which he is used with simple cases, such as spots before the eyes of an elderly patient not cleaning her glasses, fishing hook impaling and even reading mail for a young illiterate couple, Kyle and Mary Owens, whose baby he later delivers. The small-town experience soon humbles Ben when he misdiagnoses a young boy as having mitral valve regurgitation leading to late cyanosis, a case the town's curmudgeonly doctor, Aurelius Hogue, treats with a Coca-Cola. Hogue explains that the boy had chewed his father's tobacco and was given too much bismuth subnitrate as an antacid, causing a blue tinge; the carbonic acid component of the soda would relieve his stomachache. The two finally bond when Ben saves Hogue after he suffers a near-fatal heart attack. Since Hogue is eager to retire, Ben is urged by the locals to stay and replace him, although he is tempted by his budding romance with a tomboyish...???

input question: Generate a question that has the following answer: Mary for the following movie plot: Mary Henry (Candace Hilligoss) is riding in a car with two other young women when some men challenge them to a drag race. As they speed across a bridge, the women's car plunges over the side into the river. The police spend three hours dragging the murky, fast-running water without success. Mary miraculously surfaces, but she cannot remember how she survived. Mary then drives to Utah, where she has been hired as a church organist. At one point, she can get nothing on her car radio but strange organ music. She passes a large, abandoned pavilion sitting all by itself on the shores of the Great Salt Lake; it seems to beckon to her in the twilight. Shortly thereafter, while she is speeding along a deserted stretch of road, a ghoulish, pasty-faced figure (never identified, but called "The Man" in dialogue and played by director Herk Harvey, uncredited) replaces her reflection in the passenger window and stares at her. When The Man suddenly appears in front of her, she swerves off the road. At a gas station, the attendant tells her the pavilion was first a bathhouse, then a dance hall, and finally a carnival before shutting down. In town, Mary rents a room from Mrs. Thomas; John Linden, the only other lodger, wants to become better acquainted with the blonde newcomer, but she is not interested. That night, she becomes upset when she sees The Man downstairs in the large house and retreats to her room. Mrs. Thomas, who brings her some food, says she did not pass anyone. Soon, Mary begins experiencing terrifying interludes when she becomes invisible and inaudible to the rest of the world, as if she simply is not there. When The Man appears briefly in front of her in a park, she flees, right into the arms of a Dr. Samuels. He tries to help her, even as he acknowledges he is not a psychiatrist. Her new employer, the minister (Art Ellison), is put off when she declines his suggestion of a reception to meet the congregation. When she practices for the first time, she finds herself shifting from a hymn to eerie music. In a...???
