Final answer:
World War I had a significant impact on the borders of countries in Europe.
Step-by-step explanation:
The borders of countries in Europe were greatly affected by World War I. Several changes occurred as a result of the war. Germany did not become larger after the war; in fact, Germany lost territory and its borders were redrawn. Austria-Hungary was indeed divided after the war, resulting in the formation of independent countries such as Austria, Hungary, Czechoslovakia, and Yugoslavia. Serbia, on the other hand, existed prior to the war and did not undergo significant border changes. Montenegro was also an existing country before the war.
