Gold is not fully gold it's made up of other things and by adding those other metals it still isn't fully gold but it's much better and more furnished and stronger

Answer from: dondre54

First you need to some basics of chemistry. Gold as in pure gold is a metal that can be molded even by touch. Since it is soft goldsmiths add other metals(mainly copper) to make jewelry. By adding other metals it became an alloy and therefore becomes hard. To sum up, gold is mixed with other metals to retain its shape. Hope this helps!

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.

analyze the effectiveness of this excerpt. how does it function within the speech as a whole? how does the structure of the excerpt to convey the speech's purpose and key points? support your argument with evidence from the speech. (10 points)
