Final answer:
The primary work of Congress is making laws, not enforcing them or adjudicating disputes. Congress has the right to create lower courts, declare war, and engage in shaping foreign policy. Enforcement of laws is performed by the executive branch, not Congress.
Step-by-step explanation:
The primary work of Congress is b) Making laws. Congress, as the legislative branch of the U.S. government, is responsible for the creation and shaping of laws. Members of Congress get ideas for potential legislation from various sources, including their constituents, interest groups, think tanks, and their own initiatives based on observed needs.
However, it is important to note that certain powers are not among those enumerated for Congress in the U.S. Constitution. Specifically, Congress does not have the right to enforce its laws; this is the responsibility of the executive branch. Congress has many other powers, including the ability to declare war, create a lower national court system, establish rules for naturalization, and coin money.
While the president leads the country's foreign policy, Congress is also involved in foreign policy through its powers to approve treaties and agreements, allocate funding, and exert oversight. It has constitutional powers related to appointments, treaties, and war that it shares with the president. Nevertheless, the president retains significant autonomy in foreign policy matters due to the ability to use executive orders and engage in military actions without a formal declaration of war.
