Which of the following allowed for widespread exploration starting in the 1400s?

Hey!

Widespread exploration was made possible in the 1400s by the growth in wealth in Europe as well as new technological developments in ship building that made traveling far distances more attainable. The political regimes of Europe became more centralized at this time and were able to raise more funds to help support the acquisition of new trade routes and territories around the globe. New ships were built and developed at this time that also allowed for further international travel. 
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.
