A major theme of F. Scott Fitzgerald's work was the idea that the post-war world

A. presented chances to become wealthy.

B. needed new inventions to fix problems.

C. presented chances for adventure.

D. was empty and meaningless.

The correct answer of those presented is option D that is that the post-war world was empty and meaningless. In the Great Gatsby for example, you see the collapse and breakdown of those aiming at improving their position in pursuit of material things to achieve their dreams. This way of existing looks at first amazing, but it is ultimately seen to be worthless.
