Novels such as the sun also rises and the great gatsby most clearly reflect what literary theme? a.) the horrors of the experience of world war i b.) the sense of the loss of purpose of the postwar generation of writers. c.) the secret workings of the subconscious mind. d.) the desire to return to prewar values and stability

Actually, these two novels could be said to express all of these themes and ideas.  However, the authors of these two novels, F. Scott Fitzgerald and Ernest Hemingway, are considered by many critics, scholars, and historians to belong to what is known as "the lost generation" of American writers. Hemingway and Fitzgerald, in fact, have been considered to be the "leaders," in a sense, of the "lost generation" of American writers, especially given their mutual expression of purpose for the post World War I generation in their novels.
