The United States sent several billion dollars to aid the Nationalists in China because the leaders feared that a Nationalist defeat would create a communist superpower.
Here are my thoughts and responses as to what I come to know for these civilizations' achievements. I even checked my World History notes from last year...
1. Egyptians
2. Sumerians
3. Phoenicians
4. -This is debatable... We could argue early caveman or Sumerians made it, depends on what resource, textbook, or class material you are deriving this from. Maybe Hebrew because they developed Monotheism, belief in one deity.
5. Hittites
6. This is very difficult to elaborate on. Many civilizations had very strikingly similar achievements and reviewing my notes, I can't find anything to give an absolute civilization responsible for this. You'll have to guess.
7. Babylonian?
Sorry I couldn't help with #4, 6, and 7 that well. It's very difficult to answer.

I hope this helps :3
