Question

Read the introduction and first paragraph of an essay about energy sources.

(1) The nation's energy use is largely dependent on fossil fuels. (2) These fuels are nonrenewable resources, and they cause pollution. (3) We cannot continue our reliance on a fuel that will eventually run out. (4) Thus, we must find other ways to sustain our energy demands. (5) Pursuing alternative fuel sources is the key to solving our energy crisis.

(6) Through different technologies, such as solar cells, scientists have learned to use the sun’s radiation to create electricity. (7) Currently, about 1 percent of energy in the United States is produced by the sun, and solar energy has the potential to become a more widely used energy source. (8) Solar energy is both inexhaustible and clean. (9) The major limit to this alternative source is that equipment is expensive. (10) Developing a cost-effective way to harness the power of the sun will be a significant development in solving our energy crisis.

Which sentence references a counterclaim against the use of solar energy?
sentence 3
sentence 7
sentence 8
sentence 9

Answer 1

9

Step-by-step explanation:

This sentence mentions the main limitation to creating an energy grid that relies completely on solar power. It is the only sentence that questions the viability of the solar power transformation since the equipment is costly.

Sentence 3 reaffirms the need to stop using energy sources that contaminate. Sentence 7 quotes the current market share of solar energy in the United States, and sentence 8 names two advantages of solar power.
