Answer:
1. Separation of powers is the principle that divides the powers and responsibilities of a government among different branches or institutions to prevent one branch from becoming too powerful.
2. An example of separation of powers in action is the United States government. The executive branch, led by the President, enforces laws; the legislative branch, Congress, makes laws; and the judicial branch, the Supreme Court, interprets laws. Each branch has its own distinct powers and responsibilities, ensuring a system of checks and balances.
3. Separation of powers supports the ideas in the preamble by promoting democracy, protecting individual rights, and ensuring a government that works for the people. It prevents any one branch from gaining too much power, aligning with the principle of "We the People." Additionally, the checks and balances provided by the separation of powers help safeguard individual rights and prevent the abuse of power, supporting the preamble's ideas of promoting the general welfare and ensuring justice for all.
