The power given to the legislative branch of the United States federal government in Article 1, Section 8 of the United States Constitution includes the authority to:
I. Levy taxes
III. Declare war
Therefore, the correct option based on the powers listed in the question is:
I, III, and IV only
The legislative branch, which consists of the Congress, has the constitutional power to levy taxes, which is crucial for funding government operations. Additionally, the Constitution grants Congress the authority to declare war, a significant responsibility that shapes the nation's foreign policy and military actions. Appointing judges is typically a power of the executive branch, not the legislative branch.
