PROBLEM: Passage: New York City's Central Park, an oasis that functions as the city's "green lung", was in a state of deterioration in the mid-1970s. Though Central Park had been designated a National Historic Landmark in 1962, at the start of the 1980s, the city lacked the financial resources to spend an estimated US$3,000,000 to restore or even to maintain the park. The nonprofit Central Park Conservancy was founded in 1980, and began a successful campaign to raise renovation funds.In the early 1980s, Parks Commissioner Gordon Davis, responsible for New York City's green areas, and Ron Delsener, one of the city's most influential concert promoters, developed the idea of helping Central Park financially with a free open-air concert, under the legal guidance of Bob Donnelly. The city would use profits from merchandising, television, and video rights to renovate the park. Earlier park performances by Elton John and James Taylor showed that this concept could be a success. Davis authorized the project, and Delsener entered discussions with cable TV channel HBO to decide who would perform.They decided on Simon & Garfunkel, a group that had formed in New York City in the 1960s, and had been one of the most successful folk rock groups through the late 60s/early 70s. Simon & Garfunkel had broken up at the height of their popularity and shortly after the release of their fifth studio album, Bridge Over Troubled Water, which is deemed to be their artistic peak and which topped the 1970 Billboard charts for ten weeks. They had grown apart artistically and did not get along well with each other. In the following eleven years, both continued musical careers as solo artists, and worked together only sporadically on single projects. Garfunkel made brief guest appearances at Simon's concerts, which were always successful.Delsener presented the plan to Paul Simon in the summer of 1981. Simon was enthusiastic about the idea, but questioned whether it could be financially successful, especially given the poor audience attendance of his last project, the autobiographical movie One-Trick Pony. Simon's confidence had declined and he had sought treatment for depression. He questioned whether he and Art Garfunkel could work together, but contacted Garfunkel, who was vacationing in Switzerland. Garfunkel was excited about the idea, and immediately returned to the US.From the promoter's viewpoint, Simon and Garfunkel were ideal choices. Not only were they likely to draw a large crowd to the concert, they also had roots in the city –  both had grown up and gone to school in Forest Hills, Queens. Music critic Stephen Holden pointed out that, unlike artists who had left in pursuit of lifestyles offered by other locales, the two had always been a part of New York City. Both gained inspiration from the cityscape and the cultural variety of New York, and spoke of these influences in their songs. 
Question: What is the name of the city that lacked the financial resources to spend an estimated US$3,000,000 to restore or even maintain its "green lung" at the start of the 1980s??

SOLUTION: New York City.

PROBLEM: Passage: In 1933, Lewis Tater, an aspiring novelist who harbors dreams of becoming the next Zane Grey, decides to leave his family home in Iowa to go to the University of Titan in Nevada so he can soak up the western atmosphere. He arrives to find that there is no university, only a mail order correspondence course scam run by two crooks out of the local hotel. He tries to spend the night at the hotel, but is attacked by one of the men in an attempted robbery. He escapes his attacker, grabs his suitcase, and steals their car to get away, but after awhile   it runs out of gas. He looks in the car trunk, and finds a toolbox containing a revolver and ammunition. Afraid the two crooks are still in pursuit of him, he takes the tool box and his suitcase and walks off into the desert. 
Wandering and exhausted, the next morning he happens upon a threadbare film-unit from Tumbleweed Productions grinding out a "B" western. Later that day, he catches a lift with the cowboy actors to Los Angeles. After applying for work at Tumbleweed, he is referred by crusty old extra Howard Pike to the Rio, a western-themed restaurant. While washing dishes at the Rio, he is called by Tumbleweed, where Howard mentors him to be an actor. After proving himself as a stuntman, unit manager Kessler offers him a speaking role. Tater then falls in love with spunky script girl Miss Trout. Meanwhile, the crooks trace him to Los Angeles to retrieve the safe-box containing their money that was in the car stolen by Lewis. 
Question: What is the last name of the person who the crooks trace to Los Angeles?

SOLUTION: Tater.

PROBLEM: Passage: At 09:30 on 2 May, Oan appeared at the first-floor window of the embassy to demand access to the telex system, which the police had disabled along with the telephone lines, and threatened to kill Abdul Fazi Ezzati, the cultural attaché. The police refused and Oan pushed Ezzati, who he had been holding at gunpoint at the window, across the room, before demanding to speak to somebody from the BBC who knew Sim Harris. The police, relieved to have a demand to which they could easily agree, produced Tony Crabb, managing director of BBC Television News and Harris's boss. Oan shouted his demands; for safe passage out of the UK, to be negotiated by three ambassadors from Arab countries, to Crabb from the first-floor window, and instructed that they should be broadcast along with a statement of the hostage-takers' aims by the BBC. The Foreign and Commonwealth Office informally approached the embassies of Algeria, Jordan, Kuwait, Lebanon, Syria and Qatar to ask if their ambassadors would be willing to talk to the hostage-takers. The Jordanian ambassador immediately refused and the other five said they would consult their governments. The BBC broadcast the statement that evening, but in a form unsatisfactory to Oan, who considered it to be truncated and incorrect.Meanwhile, the police located the embassy caretaker and took him to their forward headquarters to brief the SAS and senior police officers. He informed them that the embassy's front door was reinforced by a steel security door, and that the windows on the ground floor and first floor were fitted with armoured glass, the result of recommendations made after the SAS had been asked to review security arrangements for the embassy several years earlier. Plans for entering the embassy by battering the front door and ground-floor windows were quickly scrapped and work began on other ideas. 
Question: What is the last name of the person who held Ezzati at gunpoint?

SOLUTION:
Oan.
