Question

(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) Currently, about 1 percent of eneigy 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 sun's 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 is the author's thesis statement?
O sentence 1
O sentence 2
O sentence 5
O sentence 6

Answer 1

Sentence 5 talks about looking for alternate energy sources but doesn't specifically mention solar energy so it is wrong. Sentence 10 says that solar energy is a "significant development" but it doesn't provide specific evidence so it is also not correct. Sentence 6 is the best answer - it shows that it is already being used and it has the potential to be used even more.
