Correct Answer: 1929-34

Solution : The correct answer is 1929-34 .

The Great Depression lasted from 1929 until 1934. It was the greatest economic slump in the history of the industrialised world, resulting in catastrophic production losses, massive unemployment and acute deflation in practically every country on the planet. The Great Depression began in the United States in the summer of 1929 as a normal recession. However, the slump grew significantly worse in late 1929 and lasted until early 1933.
