The correct statement that examines how the aftermath of World War I created economic ties between the United States and Europe, which ultimately made the Great Depression a global problem, is:
After the destruction of World War I, the U.S. government lent money to European countries that needed to rebuild.
This reflects the economic ties established through loans and reparations post-WWI, which interconnected the economies of the U.S. and Europe. When the Great Depression hit, the financial instability in the U.S. had significant repercussions for Europe, exacerbating the global economic crisis.
