The statement that best reflects how Sinclair Lewis differed from other Lost Generation authors like F. Scott Fitzgerald and Ernest Hemingway is:
• Lewis' writing was influenced more by the previous generation's progressive ideas.
While this is a simplified view, it acknowledges that Lewis was often focused on social criticism and themes related to American culture, which drew from the progressive era's ideals. His work often tackled issues in American society, such as conformity and materialism, in a way that differed from the more personal and existential themes often explored by Fitzgerald and Hemingway.
