As you read this passage, think about how to describe its tone. New research identifies cracks over the moon's crust that may have been created by the cooling and shrinking over the past billion or so years. Scientists have discovered landforms littered across the moon's surface called lobate scarps that have apparently resulted from the moon's shrinking very slowly. These scarps were found all over the moon and appear to be minimally weathered, indicating that the geologic events that created them were fairly recent. This theory contradicts the claim that the moon is completely devoid of geologic activity.

What word best describes the tone of the passage?

simple

personal

casual

formal

I would go with formal but simple seems good too.

I'm between formal and simple as well. I would appreciate if someone could help :)

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)

yes, we appreciate these things!
