Final answer:
The correct answer to the difference between state and federal government is B, where states can build roads and the federal government has the exclusive power to coin money.
Step-by-step explanation:
Which of the following describes a difference between the state and federal government? The correct answer is B. The states can build roads and the federal government can coin money. This highlights the distinct powers allocated to state governments versus the federal government. The state governments are responsible for managing matters within their own territories, which include infrastructure projects like roads. On the other hand, the federal government is granted specific powers that have nationwide implications, like minting currency, which is not a power of the states.
It is important to note that certain powers are exclusively federal, such as coining money and conducting foreign diplomacy, as outlined in Article I, Section 10 of the Constitution. Conversely, state powers include activities such as regulating commerce within the state and maintaining state militias. Some powers are shared between federal and state governments, such as the ability to levy taxes.
