There were three Nebuchadnezzar's who reigned. Assuming that you are talking about Nebuchadnezzar I, he reigned during 1125 - 1104 BC.
The following are correct:
A moat filled with water from the Euphrates River surrounded the city.
Walls around the city provided protection from enemies.
D). Vast empires.
Classical civilizations developed vast empires, whereas early river valley civilizations did not.
<span>B. If marginal production costs exceed marginal revenues, the firm will suffer losses, not profits.</span>
Assuming you're referring to the Civil War, African Americans received the best treatment in the North, since the North was fighting the war specifically to end the institution of slavery.
These laws included new powers to deport foreigners as well as making it harder for new immigrants to vote.
The Federalists believed that Democratic-Republican criticism of Federalist policies was disloyal and feared that aliens living in the United States would sympathize with the French during a war.
So, I would say B and E
Hope this helps!! If it doesn't tell me what was wrong. :)
