revise the paper into 8-10 papges according to the following comments:
1. there a lot of grammar, sentence structure and other mistakes. I had trouble understanding your argument in “The weak point of the economy” part of your paper.
2. You do a good job laying out the three phases after WWII, including your section on birth control and population decreases, but your paper ends up being more of a descriptive paper rathern than analysis.
3. Having read to the end of your paper, I am still unsure what your why question, puzzle and argument is. You need to work that out more.
