What is the primary function of the President's cabinet?

The primary function of the President's cabinet is to advise the President. Each cabinet member is the head of a specific department within the executive branch of government, such as the Department of State, Department of Defense, and others. These individuals bring expertise and insights from their respective fields to help the President make informed decisions on a wide range of issues, including national security, economic policy, and social services. The cabinet members play a crucial role in shaping policies and implementing the administration's agenda.

The other options do involve important functions within the government, but they do not accurately reflect the main purpose of the cabinet. For example, proposing new legislation is primarily the role of Congress, while representing the country abroad is a function of the President and diplomats rather than the cabinet itself. Overseeing judicial matters falls under the role of the judiciary, not the cabinet. Hence, advising the President accurately encapsulates the cabinet's essential function in the federal government.
