Which region experienced boundary changes as a result of World War I and the invasions by Hitler's Germany?

• A. Europe: Before World War II
• B. Europe: After World War II
• C. Europe: Since 1990
• D. Russia and the Former Soviet Union

Answer: (A)

The main idea is that Europe saw the most dramatic boundary changes due to World War I and the later invasions by Nazi Germany. After World War I, the map of Europe was redrawn as empires collapsed—the Austro-Hungarian and Ottoman Empires broke apart, leading to new or revised borders and the creation of countries like Poland, Czechoslovakia, and Yugoslavia. Then, as Germany expanded in the late 1930s and early 1940s, it annexed and occupied territories, further reshaping borders across Central and Western Europe. These shifts happened in Europe before and at the start of World War II, which is why this region is the best fit for the question.
