AC vs. DC
In the 1880s, the War of the Currents began. Thomas Edison developed direct current, or
DC, a type of electricity that flows in one direction. By 1887, DC was in use around the
United States. It had some drawbacks, though. Converting it to lower or higher voltages
was difficult; that is, the current's force couldn't be changed easily. Transmitted at the
low voltage needed for use in homes and businesses, it lost power after traveling only a
mile. Meanwhile, Nikola Tesla was working with alternating current, or AC. AC reverses
direction many times per second and can be changed to different voltages. At high
voltage, it can be transmitted efficiently, traveling hundreds of miles with little energy
loss. Because of its advantages, AC triumphed by the end of the nineteenth century.
What is the main idea of the passage?

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.
