Briefly explain how ONE specific historical event or development during the period 1786-1861 that is not explicitly mentioned in the excerpts could be used to support Holts interpretation.

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.

Well all those are true except one that would be that a ballad often features a refrain.
