Read the excerpt from Roosevelt's State of the Union address. We take off our hats to the farmers who have faced an unprecedented task of feeding not only a great Nation but a great part of the world. What is the effect of repeating the word great in this excerpt? It suggests that feeding troops is a hopeless cause. It illustrates how many nations are actually fighting in the war. It stresses a positive idea and invigorates the audience. It shows what a huge burden has been placed on farmers.

The answer is C - to simplify what the other lady said

It stresses a positive idea and invigorates the audience.

In the excerpt Roosevelt describes both the United States of America and a part of the world as great. The purpose of this excerpt is to praise the farmers for all of their efforts. Since the word "great" has a positive connotation and the purpose is praise, we can eliminate any options that have a negative connotation. The option about feeding the troops being a hopeless cause and the option about placing a huge burden on the farms should are both incorrect. While Roosevelt is emphasizing the monumental task the farmers have faced, he is praising their efforts and successes. The word "great" also does not illustrate how many nations are actually fighting. The use of the word "great" continues the idea that their cause is worth fighting for and all the hard work and sacrifices are worth it. It is designed to keep everyone positive in hard times.
