The behavior of human beings can be very complicated. to find out how we learn, scientists often study the activities of animals. sometimes they see how long it will take for a mouse to reach food in the center of a maze. sometimes pigeons or other animals are taught to obtain food by pressing buttons. (a) in the first experiments in space flight, trained chimpanzees and dogs were sent into orbit. (b) they proved that living things could carry out certain activities while whirling about in space. (c) one early theory likened human memory to a muscle that had to be regularly exercised in order to function properly. this theory was eventually replaced by the notion that remembering was like writing, with experience the pen and the mind a blank page. (d) but eventually this theory was also rejected. in its place came another hypothesis--that human memory functioned like a complex and well-stocked library catalog. with access to a key word, you could look up any piece of stored information. but over time that theory has also been discarded. human memory may, in fact, be too sophisticated and too complex to be explained through any one single simile or metaphor. when a paragraph contains two main ideas, it should be divided into two paragraphs. choose the letter at the point where the passage should be divided. a) a b) b c) c d) d

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

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.
