Determining a Central Idea
What is the central idea of this passage?
Elizabethans do not understand infection and contagion
as we do. It is not that they are completely ignorant as to
how illnesses spread-physicians believe they know
perfectly well-it is rather that their understanding is
very different from ours. The principal ideas
underpinning most Elizabethan medical thinking come
from Galen, who lived in the second century A. D.
Physicians will cite him as an unquestionable authority
when they explain to you that your health depends on a
balance of the four humors: yellow bile or choler, black
bile, phlegm, and blood.
- The Time Traveler's Guide to Elizabethan England,
Ian Mortimer

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.
