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) 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 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? a. sentence 1 b. sentence 2 c. sentence 5 d. sentence 6

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
