D because the Greeks did believe the gods would determine their fate. They thought if they did something wrong or disobeyed the gods, the gods would punish them, and now days we have myths saying some of the things they would believe.
The amount of territory the US currently has would have been completely different if the national government could only legislate based on what is written in the constitution.
A perfect example of this is the power to purchase land/territories from other countries. This was first done by Thomas Jefferson with the Louisiana Purchase of 1803. The US Constitution does not say that the president has the power to buy land from other countries. However, Jefferson said that this power was "implied" by the Constitution.
This idea of an implied power greatly changed the presidency/national government. Several presidents after Jefferson would follow his lead by making deals with countries for territory.
If it wasn't for this concept of implied powers, the US may not have grown to the 50 states we know it as today.
At both the Federal and State level, a bill is introduced into the legislative branch.
From there, it will be put forth for discussions and hearings on the matter. It will likely be assigned to a sub-committee, who will investigate.
More discussion will occur and eventually the legislature will vote on it and send it to the Executive (Governor or President) who will sign it or veto it. The Legislative branch will enact then or will vote to overide the veto.
Depending on what happened, the bill will become law and the appropriate agency responsible will enact regulations based on the new law.
