Final answer:
Anything that directly conflicts with federal law is invalid.
Step-by-step explanation:
The statement that anything that directly conflicts with federal law is invalid is True. According to the Supremacy Clause of the United States Constitution, federal law is the supreme law of the land and prevails over conflicting state laws. This means that if a conflict arises between a federal law and a state law, the federal law takes precedence and the state law is considered invalid.
