What is one key difference between state courts and federal courts?

The key difference highlighted in the correct choice is that state courts can address a wide range of legal issues compared to the more limited scope of federal courts. State courts typically handle cases involving family law, contracts, property, and various state statutes, reflecting the diversity of legal matters that occur within a state. In contrast, federal courts are restricted to specific types of cases typically outlined by the Constitution or federal laws, such as those involving federal statutes, disputes between states, or issues that arise under international treaties.

This distinction points to the foundational roles these court systems play in the U.S. legal framework, where state courts ensure that local laws and regulations are enforced and interpreted, while federal courts focus on upholding federal law and resolving matters that cross state lines or involve significant federal interests. This structure allows for a broader scope of legal resolution at the state level, tailored to the specifics of state law and community needs.
