Which of the following is a concurrent power, exercised by both the federal and state governments?

1. Concurrent powers are those both levels of government hold, and the chapter lists taxing, borrowing, making and enforcing laws, and establishing courts among them. 2. Levying and collecting taxes therefore belongs to both levels. 3. Coining money and entering treaties are expressly denied to the states under Article I, Section 10. 4. Regulating commerce between the states is an enumerated federal power; states regulate only intrastate commerce. _Source: OpenStax American Government 3e (CC BY 4.0), Ch 3 "American Federalism", §3.1 The Division of Powers_
