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: After her husband Martin completes a four-year prison sentence for insider trading, Emily Taylor drives into a wall in an apparent suicide attempt. Jonathan Banks, her assigned psychiatrist, prescribes a series of antidepressants, but none work. Jonathan contacts Emily's previous psychiatrist, Victoria Siebert, who suggests an experimental new drug, Ablixa. The drug seems to help Emily, but gives her sleepwalking episodes as a side effect.
One night, Emily stabs Martin to death while sleepwalking. Jonathan fights for Emily's acquittal in court. She pleads insanity and is declared not guilty on the condition that she stays in a psychiatric hospital until cleared by Jonathan. The publicity destroys Jonathan's reputation, and his colleagues assume negligence on his part.
Jonathan discovers evidence that Emily is lying; she was not depressed and faked her suicide attempts. He also discovers someone may have profited from Ablixa's fall in stock value. He interviews Emily after administering what he claims is a truth serum that will make her drowsy. Though the serum is actually saline water, she feigns drowsiness, confirming Jonathan's suspicion that she is deceiving him. When he confronts Victoria with his findings, she mails photographs to his wife Deirdre implying he had an affair with Emily. Deirdre leaves him, taking her son with her. 
Question: What is the full name of the person who begins sleepwalking?
Example Output: Emily Taylor.

Example Input: Passage: Hundreds of songs and performers have entered Melodifestivalen since its debut. Although songwriters living outside Sweden were once not allowed to enter Melodifestivalen, the 2012 contest marked the first time foreign songwriters could submit entries, provided that they collaborated with a Swedish songwriter. To be eligible, songwriters and performers must be at least sixteen years of age on the day of the first Eurovision semi-final.Until 2001, participation in the festival was limited to a single night. The number of contestants ranged from five to twelve. A two-round system was used intermittently between 1981 and 1998, in which all but five of the contestants were eliminated in a first round of voting. Failure to reach the second round under this system was seen as a major failure for a prominent artist; when Elisabeth Andreassen failed to qualify in 1984, it almost ended her career. The introduction of weekly semi-finals in 2002 increased the number of contestants to thirty-two. At least ten of the contestants must perform in Swedish. A CD of each year's competing songs has been released since 2001, and a DVD of the semi-finals and final since 2003.
Melodifestivalen has been the launch-pad for the success of popular local acts, such as Anne-Lie Rydé, Tommy Körberg, and Lisa Nilsson. The competition has played host to performers from outside Sweden, including Baccara, Alannah Myles, Katrina Leskanich, and Cornelis Vreeswijk. Melodifestivalen participants have also represented—and unsuccessfully tried to represent—other countries at Eurovision. While local success for Melodifestivalen winners is common, most contestants return to obscurity and few have major international success. The impact that the competition makes on the Swedish charts means an artist need not win the competition to earn significant domestic record sales. For example, the song which finished last at Melodifestivalen 1990, "Symfonin" by Loa Falkman, topped the Swedish singles chart. The most recent occurrence was 2016 with Samir & Viktor's song "Bada Nakna". In 2007, twenty-one participants reached Sverigetopplistan. The week after the 2008 final, songs from the festival made up the entire top fifteen on the domestic singles chart. 
Question: In what year did the Swedish domestic singles chart have 15 songs from the festival that recently allowed foreign entrants in 2012?
Example Output: 2008.

Example Input: Passage: Police arrived at the embassy almost immediately after the first reports of gunfire, and, within ten minutes, seven DPG officers were on the scene. The officers moved to surround the embassy, but retreated when a gunman appeared at a window and threatened to open fire. Deputy Assistant Commissioner John Dellow arrived nearly 30 minutes later and took command of the operation. Dellow established a temporary headquarters in his car before moving it to the Royal School of Needlework further down Princes Gate and then to 24 Princes Gate, a nursery school. From his various command posts, Dellow coordinated the police response, including the deployment of D11, the Metropolitan Police's marksmen, and officers with specialist surveillance equipment. Police negotiators made contact with Oan via a field telephone passed through one of the embassy windows, and were assisted by a negotiator and a psychiatrist. At 15:15 Oan issued the DRFLA's first demand, the release of 91 Arabs held in prisons in Khūzestān, and threatened to blow up the embassy and the hostages if this were not done by noon on 1 May.Large numbers of journalists were on the scene quickly and were moved into a holding area to the west of the front of the embassy, while dozens of Iranian protesters also arrived near the embassy and remained there throughout the siege. Shortly after the beginning of the crisis, the British government's emergency committee COBR, was assembled. COBR is made up of ministers, civil servants and expert advisers, including representatives from the police and the armed forces. The meeting was chaired by William Whitelaw, the Home Secretary, as Margaret Thatcher, the Prime Minister, was unavailable.  The Iranian government  accused the British and American governments of sponsoring the attack as revenge for the ongoing siege of the US Embassy in Tehran. Given the lack of co-operation from Iran, Thatcher, kept apprised of the situation by Whitelaw, determined that British law would be applied to the embassy, despite the Vienna Convention, under which the embassy is considered Iranian soil.At 16:30, the gunmen released their first hostage, Frieda Mozaffarian. She had been unwell since the siege began, and Oan had asked for a doctor to be sent into the embassy to treat her, but the police refused. The other hostages deceived Oan into believing that Mozaffarian was pregnant, and Oan eventually released Mozaffarian after her condition deteriorated. 
Question: What is the last name of the person that released a hostage believing she was pregnant?
Example Output:
Oan.
