Final answer:
The writers of the Lost Generation, such as F. Scott Fitzgerald and Ernest Hemingway, regarded the values of their upbringing with disillusionment and criticism, depicting a generation that had lost faith in traditional values.
Step-by-step explanation:
The writers of the Lost Generation, including F. Scott Fitzgerald, Ernest Hemingway, Sinclair Lewis, Edith Wharton, and John Dos Passos, regarded the values with which they had grown up with a sense of disillusionment and hopelessness. They felt alienated from society and expressed their despair by criticizing the middle class in their work. Many of them lived an expatriate life in Europe, particularly in Paris, to distance themselves from American society and culture. For example, Fitzgerald's novels like This Side of Paradise and The Great Gatsby depicted a generation that had lost faith in traditional values. Hemingway's works such as The Sun Also Rises and A Farewell to Arms reflected the post-war disillusionment and tragic experiences of war.
