Read the excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano. Einstein's idea of gravity had big consequences. It helped explain some observations that Newton's idea didn't account for. It also opened our minds to amazing new possibilities. For example, taking his cue from Einstein's idea that space bends, scientist Karl Schwarzschild began to think about what would happen if a place in space were extremely distorted. His light would follow the hyper-bent space, never to turn away from it. This was the first prediction of a black hole. At first, some scientists (including Einstein!) rejected Schwarzschild's ideas. Others were intrigued and began searching the skies for real black holes. Just decades later, they found the first of them. It just goes to show: sometimes, as Einstein himself once said, "Imagination is more important than knowledge."

Explanation: This statement describes the main content of this excerpt.

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.
