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: Time-Life also wanted to expand, as its existing space in 1 Rockefeller Plaza had become insufficient by 1953. In August of that year, Rockefeller Center Inc. bought a tract of land on the west side of Sixth Avenue between 50th and 51st streets. Rockefeller Center's managers originally wanted to build an extra NBC studio or a Ford vehicle showroom on the site. However, they changed their minds once they saw Time Inc.'s expansion needs: the company wanted to have its headquarters in a single building. As they would outgrow their existing space in 1 Rockefeller Plaza by 1954, the company would have to move elsewhere. Not wanting to lose Time Inc.'s tenancy, the complex's managers hired Harrison & Abramovitz, composed of Wallace Harrison and Max Abramovitz, to create plans for a building on the newly acquired plot that could house both NBC and Time. NBC later dropped out of the deal because its CEO, David Sarnoff, dissented.In 1956, two years after the demolition of the Center Theatre, officials announced the construction of a new tower, the Time-Life Building, on the western side of Sixth Avenue between 50th and 51st Streets. The 500-foot (150 m), $7 million building ($97.2 in 2018 dollars) would include connections to the existing passageway system and to the Roxy Theater directly to its west. The tower would rise as a 48-story slab, with a plaza to the east and an eight-story annex along its western and northern sides. One of Rockefeller Center's subsidiaries, Westprop Inc., bought the air rights to the original Roxy Theater located next door so that the new tower could conform to the Zoning Resolution of 1916. Time Inc. and Rockefeller Center formed a joint venture, Rock-Time Inc., which would share the tower's rent income between them. Construction on the Time-Life Building's steelwork started in April 1958, and the structure topped out in November of that year. The cornerstone of the building was laid in June 1959, after the building's structure had been completed, and the first tenants began moving into the tower in December 1959.During this time, plans called for Rockefeller Center to expand northward. Rockefeller Center, Uris Buildings Corporation, and Webb and Knapp formed another joint venture, Rock-Uris Corp., to construct a hotel to the west of 75 Rockefeller Center. However, Webb and Knapp faced monetary shortages, and the joint venture found that a hotel was not the most profitable use of the land. The joint venture instead decided to construct a glass-and-concrete 43-story office building on the site, with connections to the complex's underground concourse. In 1961, the building was named after Sperry Corporation, which leased eight floors in the future building. The planned hotel was moved to another site two blocks north, on the west side of Sixth Avenue between 53rd Streets. This became the New York Hilton at Rockefeller Center, which opened in 1963. The hotel's name was misleading because it was located outside the complex and not connected to the underground mall. The mall could not be extended anyway because the 53rd Street subway was in the way. Further expansion of Rockefeller Center on the west side of Sixth Avenue, between the Hilton and the new Time-Life Building, was not possible because the Equitable Life Assurance Society had built a tower in between the two properties. 
Question: What building's cornerstone was laid in June 1959?
Example Output: the Time-Life Building.

Example Input: Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded. 
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them. 
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?
Example Output: Richie.

Example Input: Passage: Alan Dudley Bush (22 December 1900 – 31 October 1995) was a British composer, pianist, conductor, teacher and political activist. A committed communist, his uncompromising political beliefs were often reflected in his music. He composed prolifically across a range of genres, but struggled through his lifetime for recognition from the British musical establishment, which largely ignored his works.
Bush, from a prosperous middle-class background, enjoyed considerable success as a student at the Royal Academy of Music (RAM) in the early 1920s, and spent much of that decade furthering his compositional and piano-playing skills under distinguished tutors. A two-year period in Berlin in 1929 to 1931, early in the Nazi Party's rise to power, cemented Bush's political convictions and moved him from the mainstream Labour Party to the Communist Party of Great Britain which he joined in 1935. He wrote several large-scale works in the 1930s, and was heavily involved with workers' choirs for whom he composed pageants, choruses and songs. His pro-Soviet stance led to a temporary ban on his music by the BBC in the early years of the Second World War, and his refusal to modify his position in the postwar Cold War era led to a more prolonged semi-ostracism of his music. As  a result, the four major operas he wrote between 1950 and 1970 were all premiered in East Germany.
In his prewar works, Bush's style retained what commentators have described as an essential Englishness, but was also influenced by the avant-garde European idioms of the inter-war years. During and after the war he began to simplify this style, in line with his Marxism-inspired belief that music should be accessible to the mass of the people. Despite the difficulties he encountered in getting his works performed in the West he continued to compose until well into his eighties. He taught composition at the RAM for more than 50 years, published two books, was the founder and long-time president of the Workers' Music Association, and served as chairman and later vice-president of the Composers' Guild of Great Britain. His contribution to musical life was slowly recognised, in the form of doctorates from two universities and numerous tribute concerts towards the end of his life. Since his death aged 94 in 1995, his musical legacy has been nurtured by the Alan Bush Music Trust, established in 1997. 
Question: What is the last name of the person who struggled through his lifetime for recognition from the British musical establishment?
Example Output:
Bush.
