Q. Why were the delegates carful to preserve the separation of powers?
A. Could it be because they don't want one body to be the sole ruler and decision maker. Both congress and senate should have a say?

Yes, that's correct. The delegates at the Constitutional Convention were careful to preserve the separation of powers because they wanted to prevent concentration of power in one branch of government. They understood the dangers of having a single body or individual make all the decisions and rule without any checks or balances. Instead, they believed in the importance of a system where power is divided among separate branches (legislative, executive, and judicial) and each branch has its own distinct powers and responsibilities.
To get a more detailed understanding of why the delegates were careful to preserve the separation of powers, you can look into the discussions and debates that took place during the Constitutional Convention. Reading primary sources such as the Federalist Papers or the records of the convention can provide insights into the reasoning behind their decisions. Additionally, studying the writings of the Founding Fathers, such as James Madison, Thomas Jefferson, and Alexander Hamilton, can offer valuable perspectives on the issue. By analyzing these sources, you can gain a deeper understanding of the historical context and the ideas that influenced the delegates' desire to maintain a system of checks and balances.
