I NEED HELP, WILL GIVE YOU BRAINLIEST !!! Read the following selection:

The wheel stands out as an original engineering marvel, and one of the most famous inventions. This basic technology not only made it easier to travel, but also served as the base for a huge number of other innovative technologies. Yet, the wheel is not actually that old. The oldest known wheel is from Mesopotamia, around 3500 B. C. By that time, humans were already casting metal alloys, constructing canals and sailboats, and even designing complex musical instruments such as harps.

In fact, the main invention was not the wheel itself, which was likely invented the first time someone saw a rock rolling along, but the combination of a wheel and a fixed axle, which allows the wheel to be connected to a stable platform. Without the fixed axel, the wheel has only very limited utility.

In your own words, what was the author's purpose for writing this selection? Answer in the comment box that is blow this question.

A: to inform

-the author uses an informative tone by explainging something to the reader in detail using facts and it looks like something you would see in a school book

This tells all the things which are invented are inter dependent with each other so all are inter dependent on each other and no one is a solo winner...

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)

i believe the answer is thesis, reasons, evidence, counterclaim, conclusion
