Suppose The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. It was the longest, deepest, and most widespread depression of the 20th century. Millions of people were unemployed, and many businesses closed. President Franklin D. Roosevelt implemented the New Deal to help alleviate the effects of the depression.
Can we infer that "The Great Depression only affected the United States."? Yes, no, or maybe?
