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.
They closed the Mississippi River to all American commerce in 1784. This made it difficult for American farmers to get their goods to international markets. Spain would eventually allow Americans to use the river, but placed a tariff for the privilege. <span />
<span>"C. Napoleon and his army established a revolutionary government in Rome"</span> is the best option from the list, but it should be noted that this was only a brief unification.
I know this is old, but the correct answer is D. The answer is part of the jury deliberation.
