Final answer:
The United States Government Manual provides comprehensive information on the agencies of the Legislative, Executive, and Judicial branches of the U.S. Government, which are responsible for lawmaking, implementation of laws, and law interpretation, respectively.
Step-by-step explanation:
The United States Government Manual is a comprehensive resource that provides information on the agencies of all three branches of the United States Government: the Legislative, Executive, and Judicial branches. The Legislative branch, which includes Congress, is responsible for making laws.
The Executive branch, led by the President, is tasked with implementing and executing laws. Meanwhile, the Judicial branch, which consists of the federal courts, interprets and enforces laws. The government power in the U.S. is therefore divided among these branches to ensure a balance of power and prevent any one branch from having too much control.
