Question

complete the text with the evidence that best supports the argument. in the winter, heat pumps draw in heat from the cold air outside and transfer it indoors to warm a home. in the summer, they cool down a home by absorbing the indoor heat and releasing it outside. this capacity for dual action is one of the advantages of heat pumps. in contrast, homeowners who rely on a furnace for heating must also have an air - conditioning unit or a fan system for cooling. another benefit of heat pumps is that they dont burn fossil fuels, so they are more environmentally friendly. while installing heat pumps can be expensive, homeowners are frequently able to get a tax credit for their investment. most people who use them eventually see a five hundred dollar reduction in their annual home - energy costs. though heat pumps are a less traditional method of heating and cooling, they offer positive outcomes for both homeowners and the environment. heat - pump technology has existed for decades but recently gained popularity. a common complaint about heat pumps is that they can sometimes be noisy. in addition, the enhanced efficiency of heat pumps leads to long - term savings. heat pumps tend to work best in locations with a relatively moderate climate.

Explanation:

The text emphasizes the benefits of heat - pumps like dual - action, environmental friendliness, and potential tax credits. The statement about long - term savings due to enhanced efficiency complements this by further highlighting a positive aspect related to cost, which ties in with the overall positive portrayal of heat - pumps in the text. The other options either introduce neutral information (existence and popularity), a negative (noise), or a limitation (moderate climate preference).

Answer:

In addition, the enhanced efficiency of heat pumps leads to long - term savings.
