The document outlines guidelines for writing an assignment on diversity in the U.S. from 1865 to the 1920s, emphasizing the necessity of a thesis statement, supporting examples, and proper citations from specified sources. It advises students to develop three examples from different decades to support their thesis and includes a part addressing opposing views and a conclusion reflecting on the legacy of these issues today. The final paper should reflect critical thinking on diversity's evolution and apply it to modern contexts.
