Question

both state and federal government have the power to
○ build roads and enforce laws.
○ make treaties and collect taxes.
○ make treaties and declare war.
○ build roads and make treaties.

Explanation:

To solve this, we analyze the powers of state and federal governments in the US:

• Option 1 (build roads and enforce laws): State governments can build roads (e.g., state highways) and enforce state laws. Federal government also builds roads (interstate highways) and enforces federal laws. This is a concurrent power.
• Option 2 (make treaties and collect taxes): Making treaties is a federal - only power (reserved for the federal government, specifically the President with Senate approval).
• Option 3 (make treaties and declare war): Both making treaties and declaring war are federal - only powers.
• Option 4 (build roads and make treaties): Making treaties is a federal - only power.

Answer:

A. build roads and enforce laws
