　　Questions 36 to 40 are based on the following passage:

　　The most interesting architectural phenomenon of the 1970's was the enthusiasm for refurbishing old buildings. Obviously, this was not an entirely new phenomenon. What is new is the wholesale interest in reusing the past, in recycling, in adaptive rehabilitation. A few trial efforts, such as Ghirardelli Square in San Francisco, proved their financial viability in the 1960's, but it was in the 1970's, with strong government support through tax incentives and rapid depreciation, as well as growing interest in ecology issues, that recycling became a major factor on the urban scene. One of the most comprehensive ventures was the restoration and transformation of Boston's eighteenth century Faneuil Hall and the Quincy Market, designed in 1824. This section had fallen on hard times, but beginning with the construction of a new city hall immediately adjacent, it has returned to life with the intelligent reuse of these fine old buildings under the design leadership of Benjamin Thompson. He has provided a marvelous setting for dining, shopping, professional offices, and simply walking. Butler Square, in Minneapolis, examplifies major changes in its complex of offices, commercial space, and public amenities carved out of a massive pile designed in 1906 as a hardware warehouse. The exciting interior timber structure of the building was highlighted by cutting light courts through the interior and adding large skylights.

　　San Antonio, Texas, offers an object lesson for numerous other cities combating urban decay. Rather than bringing in the bulldozers, San Antonio's leaders rehabilitated existing structures, while simultaneously cleaning up the San Antonio River, which meanders through the business district.
