Which term is defined as an established law, practice or custom?

• A. Institution
• B. Integrate evidence
• C. Inquiry
• D. Interdependence

Answer: (C)

A term that means an established law, practice, or custom points to an institution. In social studies, institutions are the lasting structures that guide how people behave and interact—things like laws, traditions, schools, family, and government. They shape daily life by providing rules and expectations that societies follow over time. The other options describe actions or concepts that aren’t about long-standing rules or patterns: integrating evidence is about combining information from sources, inquiry is about asking questions or investigating, and interdependence is about mutual reliance between people or systems. So the best fit for an established law, practice, or custom is institution.
