I want to know the answer to the following question:
What was the percentage the Dow Jones fell in the Great Depression?
All the background I'm provided with is that "He says the Dow Jones average's fall of more than 50% over a period of 17 months is similar to a 54.7% fall in the Great Depression, followed by a total drop of 89% over the following 16 months.". Is that enough to answer the question?
