a national government that shares some responsibilities and powers with the state governments but is ultimately seen as the supreme law

A federal system of government can be best described as a national government that shares some responsibilities and powers with the state governments but is ultimately seen as the supreme law.

A federal system of government can be best described as a national government that shares some responsibilities and powers with the state governments but is ultimately seen as the supreme law. To arrive at this answer, one can analyze the options given:

1. A national government with a king or queen at its head: This does not align with the concept of federalism as federal systems typically have elected representatives as the head of the national government, not monarchs.

2. A state government that looks toward a national government for ideas: While a state government may consider or draw inspiration from the national government, the essence of federalism is more about the distribution of power and the existence of separate levels or tiers of government, rather than one looking towards the other for ideas.

3. A series of state governments working independently from one another: This answer choice is closer to the notion of a confederal system rather than a federal system. In a confederation, state governments typically have a higher level of autonomy and relatively little involvement in the affairs of the other states.

4. A national government that shares some responsibilities and powers with the state governments but is ultimately seen as the supreme law: This answer accurately captures the essence of a federal system. In such a system, power is divided and shared between the national government and the state governments, with each having their own distinct authority and autonomy. However, the national government has the ultimate authority and its laws and decisions apply to the entire country.

Therefore, the correct answer is: a national government that shares some responsibilities and powers with the state governments but is ultimately seen as the supreme law.
