Input: Consider Input: Passage: Filmmaker Adam Green begins a documentary about artwork that features monsters.  Green is surprised when William Dekker, a retired police officer, contacts him and claims to have proof of the existence of monsters.  Green's wife reacts skeptically, but he reworks his documentary to focus on Dekker and his efforts to expose the monsters' underground home, which he calls "The Marrow". Green interviews Dekker at his house, who claims that he has seen many monsters and identified some of them through sketches. Dekker mentions his son once but diverts from the topic when Green inquires. The shooting crew of Green and his cameraman wait at the Marrow's entrance; a dug-up hole in the cemetery in the woods. On the first night they do not see anything although Dekker keeps claiming that he could see one of the monsters. 
Question: What does the person contacted by the police officer do for a living?

Output: Filmmaker.


Input: Consider Input: Passage: Lennon met Cynthia Powell (1939–2015) in 1957, when they were fellow students at the Liverpool College of Art. Although Powell was intimidated by Lennon's attitude and appearance, she heard that he was obsessed with the French actress Brigitte Bardot, so she dyed her hair blonde. Lennon asked her out, but when she said that she was engaged, he screamed out, "I didn't ask you to fuckin' marry me, did I?" She often accompanied him to Quarrymen gigs and travelled to Hamburg with McCartney's girlfriend to visit him. Lennon was jealous by nature and eventually grew possessive, often terrifying Powell with his anger and physical violence. Lennon later said that until he met Ono, he had never questioned his chauvinistic attitude toward women. He said that the Beatles song "Getting Better" told his own story, "I used to be cruel to my woman, and physically – any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace."Recalling his July 1962 reaction when he learned that Cynthia was pregnant, Lennon said, "There's only one thing for it Cyn. We'll have to get married." The couple wed on 23 August at the Mount Pleasant Register Office in Liverpool, with Brian Epstein serving as best man. His marriage began just as Beatlemania was taking off across the UK. He performed on the evening of his wedding day and would continue to do so almost daily from then on. Epstein feared that fans would be alienated by the idea of a married Beatle, and he asked the Lennons to keep their marriage secret. Julian was born on 8 April 1963; Lennon was on tour at the time and did not see his infant son until three days later.Cynthia attributed the start of the marriage breakdown to Lennon's use of LSD, and she felt that he slowly lost interest in her as a result of his use of the drug. When the group travelled by train to Bangor, Wales in 1967 for the Maharishi Yogi's Transcendental Meditation seminar, a policeman did not recognise her and stopped her from boarding. She later recalled how the incident seemed to symbolise the end of their marriage. After Cynthia arrived home at Kenwood, she found Lennon with Ono and left the house to stay with friends. Alexis Mardas later claimed to have slept with her that night, and a few weeks later he informed her that Lennon was seeking a divorce and custody of Julian on the grounds of her adultery with him. After negotiations, Lennon capitulated and agreed to let her divorce him on the same grounds. The case was settled out of court in November 1968, with Lennon giving her £100,000 ($240,000 in US dollars at the time), a small annual payment and custody of Julian. 
Question: What is the first name of the child of the person that began to use LSD and lose interest in his wife?

Output: Julian.


Input: Consider Input: Passage: By the time Smetana completed his schooling, his father's fortunes had declined. Although František now agreed that his son should follow a musical career, he could not provide financial support. In August 1843 Smetana departed for Prague with twenty gulden, and no immediate prospects. Lacking any formal musical training, he needed a teacher, and was introduced by Kateřina Kolářová's mother to Josef Proksch, head of the Prague Music Institute—where Kateřina was now studying. Proksch used the most modern teaching methods, drawing on Beethoven, Chopin, Berlioz and the Leipzig circle of Liszt. In January 1844 Proksch agreed to take Smetana as a pupil, and at the same time the young musician's financial difficulties were eased when he secured an appointment as music teacher to the family of a nobleman, Count Thun.For the next three years, besides teaching piano to the Thun children, Smetana studied theory and composition under Proksch. The works he composed in these years include songs, dances, bagatelles, impromptus and the G minor Piano Sonata. In 1846 Smetana attended concerts given in Prague by Berlioz, and in all likelihood met the French composer at a reception arranged by Proksch. At the home of Count Thun he met Robert and Clara Schumann, and showed them his G minor sonata, but failed to win their approval for this work—they detected too much of Berlioz in it. Meanwhile, his friendship with Kateřina blossomed. In June 1847, on resigning his position in the Thun household, Smetana recommended her as his replacement. He then set out on a tour of Western Bohemia, hoping to establish a reputation as a concert pianist. 
Question: What is the name of the person who is František's son?


Output: Smetana.
