Question

how does federalism help voices of smaller groups be heard?
it creates a system that makes the us constitution the highest law in the entire country.
it allows the federal government to use force, ensuring political power of smaller groups.
it gives state governments power to make laws that dont apply to the majority of the nation.
it forces all citizens to cast a vote in elections at the local, state, and federal level.

Explanation:

Federalism divides power between national and state governments. State governments can make laws relevant to their specific populations. Smaller groups within a state may have more influence at the state level as it's closer to them compared to the national level. So, state - level law - making (where state governments have power) can help smaller groups' voices be heard as their state - specific needs can be addressed through state laws that may not apply nationwide (but are relevant to their state where they are a part of the population).

Answer:

It gives state governments power to make laws that don't apply to the majority of the nation.
