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.

although few humans per year are attacked by polar bears, any individual attack can be terrifying and even fatal. the warming of arctic regions has allowed the intrusion of humans into the polar bears’ habitat, increasing the danger of harmful contacts. remaining alert and using precautions can humans avoid a negative encounter with a polar bear. traveling together and staying close to the group can humans avoid bear attacks. certain weapons, including nonlethal ones such as pepper spray, are effective against polar bears. once a bear has decided to attack, however, nothing can be done.

3.select the sentence in this passage that demonstrates the fallacy of making an extreme either-or claim.

the civil war was the bloodiest conflict in the history of the united states. more than 600,000 soldiers lost their lives. the fighting took place in many different cities and throughout the countryside. the wounded often suffered acute pain while in the field hospitals. they all should have asked for better care. william hammond, the surgeon general of the union army, created a new system of sanitary field care. if people do not accept hammond as the most important person from the civil war, they have no understanding of the war.
