1. With which of the following generalizations about geothermal heating would the author of the passage most likely agree?
(A) Geothermal heating is an effective substitute for heating sources that use nonrenewable resources.
(B) Although it represents one form of green energy, geothermal heating is not universally appropriate.
(C) Because they use energy from the Earth, geothermal heating and cooling work best at low latitudes.
(D) A geothermal heating system with horizontal piping is far more efficient than one with vertical piping.
(E) State and federal governments should provide further incentives for switching to geothermal heat.
(A) This generalization aligns with the main points made in the passage, which highlight the advantages of geothermal heating as a green energy alternative that is energy efficient and environmentally clean. The passage emphasizes how geothermal heating utilizes the Earth's natural warmth, making it a sustainable option compared to heating sources that rely on nonrenewable resources like oil or gas.
(B) While geothermal heating may not be universally appropriate for all situations, the passage does not suggest that it is not a viable green energy alternative. The advantages of geothermal heating are clearly outlined, making this generalization less likely.
(C) The passage does not mention that geothermal heating works best at low latitudes. In fact, geothermal heating is effective in various regions, not limited to specific latitudes. This generalization is not supported by the information provided in the passage.
(D) The passage does not make any direct comparison between the efficiency of geothermal heating systems with horizontal piping versus vertical piping. Both types of systems are mentioned as components of geothermal heating, and the passage does not indicate that one is far more efficient than the other. This generalization is not supported by the passage.
(E) While the passage mentions government loans and tax credits that make switching to geothermal heat more affordable, it does not explicitly state that further incentives should be provided. The passage focuses more on the advantages and cost-effectiveness of geothermal heating rather than calling for additional incentives. This generalization is not directly supported by the passage.
