the creation of new
european nations
germany becoming a
superpower
the collapse of the u.s.
economy
the end of nationa

Explanation:

To determine the long - term result of WWI, we analyze each option:

• Option "Germany becoming a superpower": After WWI, Germany was severely weakened by the Treaty of Versailles (large reparations, military restrictions), so it did not become a superpower.
• Option "The collapse of the U.S. economy": The U.S. economy boomed during and after WWI (it was a major supplier of goods to the warring nations), and the Great Depression (which was a later economic collapse) was not a direct long - term result of WWI in this way.
• Option "The creation of new European nations": After WWI, the Austro - Hungarian Empire, Ottoman Empire, and Russian Empire (in part) collapsed. This led to the creation of new nations like Czechoslovakia, Yugoslavia, and the re - drawing of borders in Europe, creating new European nations.

Answer:

The creation of new European nations
