4. what was the purpose of the berlin wall, and what did it come to symbolize?

Purpose:
The wall symbolized the lack of freedom under communism. It symbolized the Cold War and divide between the communist Soviet bloc and the western democratic, capitalist bloc. 

Hope this helps.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
