Which excerpt from "the enigma machine” supports the idea that allied forces expected the germans to complicate their coding system? the enigma machine was invented at the end of world war i by german engineer arthur scherbius. he used rotors and an electrical pathway in his design. the telegram was intercepted and deciphered by british intelligence, and it caused such outrage in the us that it generate public support for the united states’ entry into the war. after 1938, when the germans introduced additional rotors and plugs to increase the number of possible combinations, polish and british cryptologists had already developed alternative methods of recovering the daily keys. the two main weaknesses of the enigma machine were careless operators and the distribution of the daily key. the daily key was printed on paper, and it had the potential of being captured en route to the field.

you need to explain that more, your grammer just needs to be close to perfect.

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.
