An agreed set of regulations, conventions and customs by which a country or an organisation is governed is the ________

Step 1: Analyze the question The question asks for the term describing an agreed set of regulations, conventions and customs by which a country or organisation is governed.

Step 2: Explain the concepts

• Constitution: The fundamental body of rules, laws, conventions and customs that determines how a state or organisation is structured and governed. It may be written (like Nigeria's 1999 Constitution) or unwritten (like the United Kingdom's).
• Sovereignty: The supreme power or authority of a state to rule itself without external control.
• Suffrage: The right to vote in elections.
• Culture: The way of life, beliefs, values and traditions of a people. It is not specifically a set of governing rules.

Step 3: Match the definition The key phrases are "agreed set of regulations, conventions and customs" and "by which a country or organisation is governed." This is the textbook definition of a constitution. It also applies to organisations, such as a students' union or a political party, which have their own constitutions.

• B: Sovereignty is about supreme authority, not a set of rules.
• C: Suffrage is only about voting rights.
• D: Culture is broader and not a formal governing framework.

Step 4: Answer The correct option is A. constitution.

Tip: When you see "rules," "laws," or "governed by" together with "conventions and customs," think constitution. For sovereignty, think "supreme power." For suffrage, think "vote."
