Which of the following is a non-legislative power of Congress?

a. creating taxes to raise money

b. determining the middle wage

c. regulating interstate and foreign trade

d. creating or coining money

I believe the answer is c

B) determining the middle wage

Non-legislative is defined as powers or responsibilities that are NOT related to lawmaking. Some of these include impeachment power, investigative power, and confirmation power. They do NOT deal with anything with money, laws, military or foreign policy. Choices A, C & D can then be eliminated. A and D both have to do with money, which is legislative. C deals with foreign policy, which is also legislative. So, the only answer to fit this question would be B.
