Explanation:

This is the thesis statement that would be too broad for a short research report. In order to write a short research report, we need to be aware of the limited number of topic we can touch on. Therefore, if we are going to talk about the Civil War, we would need to limit our topics to two or three. By saying that there were "many reasons," we are being too vague and therefore, too broad on our thesis statement.

Nebraska's harsh and physically demanding way of life

When looking back on the short story, “A Wagner Matinee,” by Willa Sibert Cather, we are introduced to Aunt Georgina with descriptions of how she would have to get her water back in Nebraska from a “lagoon” as well as other hardships one might expect when living out of the city in the early 1900s.  This is followed (contrasted) with the image/symbolism of everything that is implied with classical music of the Boston Symphony Orchestra (a symphony of Wagner)—higher living expectations and conveniences of city living.  As such, the contrast is with Boston’s civilized life and Nebraska’s harsh/demanding way of life.
