Passage: "Imagine" is a song co-written and performed by English musician John Lennon. The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace without the barriers of borders or the divisions of religion and nationality and to consider the possibility that the whole of humanity would live unattached to material possessions. Shortly before his death, Lennon said that much of the song's "lyric and content" came from his wife Yoko Ono, and in 2017, she received a co-writing credit.Lennon and Ono co-produced the song and album of the same name with Phil Spector. Recording began at Lennon's home studio at Tittenhurst Park, England, in May 1971, with final overdubs taking place at the Record Plant, in New York City, during July. One month after the September release of the LP, Lennon released "Imagine" as a single in the United States; the song peaked at number three on the Billboard Hot 100 and the LP reached number one on the UK chart in November, later becoming the most commercially successful and critically acclaimed album of Lennon's solo career. Although not originally released as a single in the United Kingdom, it was released in 1975 to promote Shaved Fish, a compilation LP and it reached number six on the chart that year. The photograph on the cover was taken by May Pang in 1974. The song has since sold more than 1.6 million copies in the UK; it reached number one following Lennon's murder in December 1980. In 1985, the Central Park Conservancy memorialised a portion of the park in honour of Lennon, called Strawberry Fields, with a mosaic that reads "Imagine".BMI named "Imagine" one of the 100 most-performed songs of the 20th century. The song ranked number 30 on the Recording Industry Association of America's list of the 365 Songs of the Century bearing the most historical significance. It earned a Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. A UK survey conducted by the Guinness World Records British Hit Singles Book named it the second best single of all time, while Rolling Stone ranked it number three in their list of "The 500 Greatest Songs of All Time". Since 2005, event organisers have played it just before the New Year's Times Square Ball drops in New York City. Dozens of artists have performed or recorded versions of "Imagine", including Madonna, Stevie Wonder, Joan Baez, Lady Gaga, Elton John and Diana Ross. Emeli Sandé recorded a cover for the BBC to use during the end credits montage at the close of the 2012 Summer Olympics coverage in August 2012. "Imagine" subsequently re-entered the UK Top 40, reaching number 18.

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?

Ex Output:
the Time-Life Building.

Passage: In 1987, James Brennan plans to have a summer vacation in Europe after graduating with a comparative literature degree from Oberlin College and to attend a journalism graduate school at Columbia University when his holidays end. A few days after his graduation, his parents advise him to seek a part-time job rather than going to Europe when they unexpectedly announce that financial problems have taken a toll on them and they would be unable to financially support him.
James gets a job at Adventureland, a local amusement park in his hometown of Pittsburgh, Pennsylvania, where his childhood friend Tommy Frigo works. Assistant manager Bobby assigns James to the games area. He meets his co-workers: sarcastic Joel; Bobby's wife and park manager Paulette; Sue O'Malley; Mark; the alluring Lisa P.; and the park's technician, Mike Connell, a part-time musician. Another games worker, Emily "Em" Lewin, saves James from being stabbed by a lying, cheating customer.
With her father and stepmother away, Em throws a party and gets to know James. During the conversation, Em persuades James to join her in the house's swimming pool. After Em leaves the pool, James follows only to jump back into the water in humiliation when Frigo announces to the partygoers that he saw James having an erection while leaving the pool. After the party, Connell, who has been having an affair with Em, comes over to further pursue it. 
Question: What's the first name of the person who works in the same area of the park as Em?

Ex Output:

James.
