GRE Sample Test 3 Verbal Reasoning 2

Questions 8 to 10 refer to the passage below.
For each question, select one answer choice, unless the instructions state otherwise

Historic buildings are often regarded as energy inefficient in measurement systems that focus solely on annual energy usage. This approach ignores two important factors: (1) the annual energy use in an appropriately rehabilitated historic building is not measurably
5 greater than for a new building; and (2) 15 to 30 times as much energy is used in the construction of a building than its annual operation. For an existing building, the energy expended in construction has already been “embodied” in the structure. When the energy consumption analysis is approached from a life-cycle perspective, wherein both the
10 energy needed to construct the building as well as annual energy usage is included, the energy inefficiency claim against historic buildings largely disappears. This is an area, however, where more research and more widely dispersed research is necessary.
