Task: Question Generation
Input (English): Passage: Kennedy's assassination led indirectly to another commission for Pei's firm. In 1964 the acting mayor, Erik Jonsson, began working to change the community's image. Dallas was known and disliked as the city where the president had been killed, but Jonsson began a program designed to initiate a community renewal. One of the goals was a new city hall, which could be a "symbol of the people". Jonsson, a co-founder of Texas Instruments, learned about Pei from his associate Cecil Howard Green, who had recruited the architect for MIT's Earth Sciences building.Pei's approach to the new Dallas City Hall mirrored those of other projects; he surveyed the surrounding area and worked to make the building fit. In the case of Dallas, he spent days meeting with residents of the city and was impressed by their civic pride. He also found that the skyscrapers of the downtown business district dominated the skyline, and sought to create a building which could face the tall buildings and represent the importance of the public sector. He spoke of creating "a public-private dialogue with the commercial high-rises".Working with his associate Theodore Musho, Pei developed a design centered on a building with a top much wider than the bottom; the facade leans at an angle of 34 degrees. A plaza stretches out before the building, and a series of support columns holds it up. It was influenced by Le Corbusier's High Court building in Chandigarh, India; Pei sought to use the significant overhang to unify building and plaza. The project cost much more than initially expected, and took 11 years. Revenue was secured in part by including a subterranean parking garage. The interior of the city hall is large and spacious; windows in the ceiling above the eighth floor fill the main space with light.
The city of Dallas received the building well, and a local television news crew found unanimous approval of the new city hall when it officially opened to the public in 1978. Pei himself considered the project a success, even as he worried about the arrangement of its elements. He said: "It's perhaps stronger than I would have liked; it's got more strength than finesse." He felt that his relative lack of experience left him without the necessary design tools to refine his vision, but the community liked the city hall enough to invite him back. Over the years he went on to design five additional buildings in the Dallas area.
