Final Answer:
The Tenth Amendment does not grant police powers to act as a professional writer.
Explanation:
The Tenth Amendment to the United States Constitution reserves powers not delegated to the federal government to the states or the people. Police powers typically involve state authority to regulate health, safety, and welfare. Acting as a professional writer is not a recognized police power granted by the Tenth Amendment. Police powers are more aligned with matters such as public safety, law enforcement, and health regulations.
