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: On Christmas Eve in 19th-century London, Fred is sliding on ice on a sidewalk. He meets Peter and Tim Cratchit, sons of his uncle Ebenezer's clerk, Bob Cratchit. When Fred reveals who he is, the boys take off in terror. Fred soon arrives at the counting-house of his miserly maternal uncle, Ebenezer Scrooge. After declining an invitation from his nephew to dine with him on Christmas, Scrooge rejects two gentlemen collecting money for charity. That night, Scrooge reluctantly allows his employee Bob Cratchit to have Christmas off with pay but orders him back all the earlier the day after. Later Bob accidentally knocks off Scrooge's hat with a snowball. Scrooge dismisses Bob and withholds a week's pay to compensate for his ruined hat, also demanding a shilling to make up the difference. Bob spends the last of his wages on food for his family's Christmas dinner. 
In his house, Scrooge is confronted by the ghost of his deceased business partner, Jacob Marley, who warns Scrooge to repent his wicked ways or he will be condemned in the afterlife as Marley was. He tells Scrooge he will be haunted by three spirits.
At one o'clock, Scrooge is visited by the youthful Ghost of Christmas Past, who takes him back in time to his early life. Scrooge is shown his unhappiness when he was left to spend the holidays alone at school, and his joy when his sister, Fran, came to take him home for Christmas. The spirit reminds Scrooge that Fran, dead for some years, is the mother of his nephew. Scrooge is shown his early career in business and money lending as an employee under Fezziwig. 
Question: Who explains that there will be three spirits?
Example Output: Jacob Marley.

Example Input: Passage: By the 18th century, the menagerie was open to the public; admission cost three half-pence or the supply of a cat or dog to be fed to the lions. By the end of the century, that had increased to 9 pence. A particularly famous inhabitant was Old Martin, a large grizzly bear given to George III by the Hudson's Bay Company in 1811. An 1800 inventory also listed a tiger, leopards, a hyena, a large baboon, various types of monkeys, wolves and "other animals". By 1822, however, the collection included only a grizzly bear, an elephant and some birds. Additional animals were then introduced. In 1828 there were over 280 representing at least 60 species as the new keeper Alfred Copps was actively acquiring animals.After the death of George IV in 1830, a decision was made to close down the Menagerie. In 1831, most of the stock was moved to the London Zoo which had opened in 1828. The last of the animals left in 1835, relocated to Regent's Park. This decision was made after an incident, although sources vary as to the specifics: either a lion was accused of biting a soldier, or a sailor, Ensign Seymour, had been bitten by a monkey. The Menagerie buildings were removed in 1852 but the Keeper of the Royal Menagerie was entitled to use the Lion Tower as a house for life. Consequently, even though the animals had long since left the building, the tower was not demolished until the death of Copps, the last keeper, in 1853.In 1999, physical evidence of lion cages was found, one being 2x3 metres (6.5x10 feet) in size, very small for a lion that can grow to be 2.5 meters (approximately 8 feet) long. In 2008, the skulls of two male Barbary lions (now extinct in the wild) from northwest Africa were found in the moat area of the Tower. Radiocarbon tests dated them from 1280–1385 and 1420–1480. During 2011 an exhibition was hosted at the Tower with fine wire sculptures by Kendra Haste. 
Question: What was the last name of the person who was bitten by a monkey?
Example Output: Seymour.

Example Input: Passage: The historic center of San Francisco is the northeast quadrant of the city anchored by Market Street and the waterfront. It is here that the Financial District is centered, with Union Square, the principal shopping and hotel district, and the Tenderloin nearby. Cable cars carry riders up steep inclines to the summit of Nob Hill, once the home of the city's business tycoons, and down to the waterfront tourist attractions of Fisherman's Wharf, and Pier 39, where many restaurants feature Dungeness crab from a still-active fishing industry. Also in this quadrant are Russian Hill, a residential neighborhood with the famously crooked Lombard Street; North Beach, the city's Little Italy and the former center of the Beat Generation; and Telegraph Hill, which features Coit Tower. Abutting Russian Hill and North Beach is San Francisco's Chinatown, the oldest Chinatown in North America. The South of Market, which was once San Francisco's industrial core, has seen significant redevelopment following the construction of AT&T Park and an infusion of startup companies. New skyscrapers, live-work lofts, and condominiums dot the area. Further development is taking place just to the south in Mission Bay area, a former railroad yard, which now has a second campus of the University of California, San Francisco, and where the new Warriors arena will be built.West of downtown, across Van Ness Avenue, lies the large Western Addition neighborhood, which became established with a large African American population after World War II. The Western Addition is usually divided into smaller neighborhoods including Hayes Valley, the Fillmore, and Japantown, which was once the largest Japantown in North America but suffered when its Japanese American residents were forcibly removed and interned during World War II. The Western Addition survived the 1906 earthquake with its Victorians largely intact, including the famous "Painted Ladies", standing alongside Alamo Square. To the south, near the geographic center of the city is Haight-Ashbury, famously associated with 1960s hippie culture. The Haight is now home to some expensive boutiques and a few controversial chain stores, although it still retains some bohemian character.
North of the Western Addition is Pacific Heights, an affluent neighborhood that features the homes built by wealthy San Franciscans in the wake of the 1906 earthquake. Directly north of Pacific Heights facing the waterfront is the Marina, a neighborhood popular with young professionals that was largely built on reclaimed land from the Bay. 
Question: What location is the new Warriors arena being built?
Example Output:
second campus of the University of California.
