Question

(1) the nations 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) 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. (7) through different technologies, such as solar cells, scientists have learned to use the suns radiation to create electricity. (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 contains evidence that solar energy could help solve the energy crisis?
sentence 5
sentence 8
sentence 9
sentence 10

Explanation:

• Sentence 5 is a general statement about pursuing alternative fuel sources, not specific to solar energy.
• Sentence 8 states that solar energy is both inexhaustible and clean. These are positive attributes that show its potential to help solve the energy crisis as it addresses the non - renewable and pollution issues of fossil fuels.
• Sentence 6 is about the current percentage of solar energy use and its potential to be more widely used, but it is more of a statement about its potential rather than direct evidence of its ability to solve the crisis.
• Sentence 10 is about the cost - effectiveness issue of solar energy, which is a limitation rather than evidence of its ability to solve the crisis.

Answer:

Sentence 8
