Question 7 is based on the passage below. Select one answer choice.

Evidence indicates that the wavelengths emitted by distant stars in the

galaxy are longer than would be expected, given the atmospheres of the

stars. Most astrophysicists agree that a longer wavelength emitted by a

star signifies an increased distance. From this information, scientists

claim that the universe is expanding.

7. The two items that appear in boldface play which of the following roles?
   A The first boldfaced phrase provides evidence in support of a claim;
   the second boldfaced statement is that claim.
   B The first boldfaced phrase provides a claim in opposition to another
   claim; the second boldfaced statement is that claim.
   C The first boldfaced phrase provides a claim in support of a larger
   claim; the second boldfaced statement is that claim.
   D Both boldfaced phrases provide evidence in support of a major claim.

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

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

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.

8. The passage suggests that which of the following are advantages of
   an “appropriately rehabilitated historic building” relative to a newly
   constructed building? (Indicate all that apply.)
   A The historic building will use less energy on an annual basis.
   B Rehabilitating a historic building uses less energy than constructing a
   new building.
   C The life-cycle energy use of a historic building is no greater than that
   of a newly constructed building.
