How to properly use and punctuate a adjective clause to combine sentences?

An adjective clause does not express a complete thought, so it cannot stand alone as a sentence. To avoid writing a fragment, you must connect each adjective clause to a main clause. For each sentence, you will have to decide if the adjective clause is essential or nonessential and then use commas accordingly.   Essential clauses do not require commas. An adjective clause is essential when you need the information it provides.   Look at this example:

The vegetables that people leave uneaten are often the most nutritious. If, however, we eliminate vegetables and choose a more specific noun instead, the adjective clause becomes nonessential and does require commas to separate it from the rest of the sentence: Broccoli, which people often leave uneaten, is very nutritious.

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.
