After World War II, the United States promised to protect Japan in case of war. Japan was able to spend money to improve its economy instead of paying for a military force. How did this have a major effect on the U. S. economy?

Both United States and Japan had an advantage. Japan was able to fix their economy and become ally with the united states. The united states got to trade with japan rich resources and increase their economy.  

one way archaeology us understand the past is through the material objects it finds, allowing us to know what was being used, and when. for example a dig recently found a flute, believed to be the oldest musical instrument found to date.

i hope this
