"the pre-world war i period saw political and economic reform and a volatile economic climate that heralded a new era for the united states. during this period, immigration was a major force, with nearly 9 million immigrants entering the united states between 1900 and 1910. later, the country became embroiled in the great war, which required the federal government for the first time to attempt to place significant controls over the economy. after the transition from the war, the country experienced an extended period of prosperity that ended in 1929 and when the country entered the great depression. the depth of the depression would ultimately provide the catalyst for a change in how workers viewed self-sufficiency that would, in turn, give way to changes in how american workers were paid." courtesy of the united states bureau of labor statistics

Explanation:

An introduction is a crucial part of any writing. Therefore when writing any piece, you must give a brief overview of what the whole text will be about. The ideas that are provided in the introduction enables the reader a chance to understand and have a brief of what to read about. In simple terms the introduction states the thesis of the entire work. Before writing an academic work of another essay always starts your work with a summary that explains what the test entails.

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.
