In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: In 1996 the Pumpkins undertook an extended world tour in support of Mellon Collie. Corgan's look during this period—a shaved head, a long sleeve black shirt with the word "Zero" printed on it, and silver pants—became iconic. That year, the band also made a guest appearance in an episode of The Simpsons, "Homerpalooza". With considerable video rotation on MTV, major industry awards, and "Zero" shirts selling in many malls, the Pumpkins were considered one of the most popular bands of the time. But the year was far from entirely positive for the band. In May, the Smashing Pumpkins played a gig at the Point Theatre in Dublin, Ireland. Despite the band's repeated requests for moshing to stop, a seventeen-year-old fan named Bernadette O'Brien was crushed to death. The concert ended early and the following night's performance in Belfast was cancelled out of respect for her. However, while Corgan maintained that moshing's "time [had] come and gone", the band would continue to request open-floor concerts throughout the rest of the tour.The band suffered a personal tragedy on the night of July 11, 1996, when touring keyboardist Jonathan Melvoin and Chamberlin overdosed on heroin in a hotel room in New York City. Melvoin died, and Chamberlin was arrested for drug possession. A few days later, the band announced that Chamberlin had been fired as a result of the incident. The Pumpkins chose to finish the tour, and hired drummer Matt Walker and keyboardist Dennis Flemion. Corgan later said the decision to continue touring was the worst decision the band had ever made, damaging both their music and their reputation. Chamberlin admitted in a 1994 Rolling Stone cover story that in the past he'd "gotten high in every city in this country and probably half the cities in Europe." But in recent years, he had reportedly been clean. On July 17, the Pumpkins issued a statement in which they said, "For nine years we have battled with Jimmy's struggles with the insidious disease of drug and alcohol addiction. It has nearly destroyed everything we are and stand for. … We wish [him] the best we have to offer". Meanwhile, the band had given interviews since the release of Mellon Collie stating that it would be the last conventional Pumpkins record, and that rock was becoming stale. James Iha said at the end of 1996, "The future is in electronic music. It really seems boring just to play rock music.". 
Question: What is the last name of the member of the band that overdose but survived?
Example Output: Chamberlin.

Example 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?
Example Output: Julian.

Example Input: Passage: The unnamed Narrator is an automobile recall specialist who is unfulfilled by his job and possessions, and has developed severe insomnia. He finds catharsis by posing as a sufferer of testicular cancer and other afflictions in support groups, remedying his insomnia. His bliss is disturbed by another impostor, Marla Singer, whose presence reminds him he is attending these groups dishonestly. The two agree to split which groups they attend, but not before they exchange contact details on the premise of switching groups at short notice.
On a flight home from a business trip, the Narrator meets and interacts with soap salesman Tyler Durden. The Narrator returns home to find that his apartment has been destroyed by an explosion. Deciding against asking Marla for help, he calls Tyler, and they meet at a bar. Tyler says the Narrator is beholden to consumerism. In the parking lot, he asks the Narrator to hit him, and they begin a fistfight.
The Narrator is invited to move into Tyler's home: a large, dilapidated house in an industrial area. They have further fights outside the bar, which attract growing crowds of men. The fights move to the bar's basement where the men form Fight Club, which routinely meets for the men to fight recreationally.
Marla overdoses on pills and telephones the Narrator for help; he ignores her, but Tyler picks up the phone and goes to her apartment to save her. Tyler and Marla get sexually involved, and Tyler warns the Narrator never to talk to Marla about him. The Narrator blackmails his boss and quits his job. 
Question: What is the last name of the person who invites the Narrator to move into his house?
Example Output:
Durden.
