Final answer:
Two descriptions of federalism are the division of power between the states and the national government of the United States, and the distribution of power between national and provincial governments.
Step-by-step explanation:
The descriptions or examples of federalism are:
- B) The states and national government of the United States - This is a description of the federal system where power is divided between a national government and various state governments.
- C) Distribution of power between national and provincial governments - This is a hallmark of federalism, with authority shared across different levels of government.
Regarding the other options, A) is incorrect because the Tenth Amendment reserves powers for the states, not the national government. D) is also not a description of federalism, as restrictions on elections and state officials don't necessarily describe the structure of federalism itself.
