According to the tables you read, China was the world’s leading steel producer in 2006. Based on what you know about the changes and resources that helped the United States’ industries to grow, what changes would you expect to be taking place in China? Write your response in a paragraph.

Answer:

I would expect China to be experiencing many of the same kinds of changes that helped U.S. industries grow. Natural resources are becoming more available, and Chinese industries are finding new sources of raw materials to support steel production. Cities are growing quickly and becoming important centers of manufacturing. These changes in resources and urban growth help explain why China became the world’s leading steel producer by 2006.
