A constitution that is very flexible is _____ constitution

Analyze the question: It asks which type of constitution is described as "very flexible." This is about the classification of constitutions in Government.

Explain the concept:

• Written constitution: Codified in one or a few documents (e.g., Nigeria's 1999 Constitution, USA). It is usually rigid because amending it requires a special, difficult procedure.
• Unwritten constitution: Not codified in a single document. It comes from customs, conventions, statutes, and judicial decisions (e.g., Britain's). It is usually flexible because it can be changed by an ordinary act of the legislature, or evolve through conventions.
• Rigid constitution: Hard to amend, needing special majorities or referendums. This is the opposite of flexible.
• Flexible constitution: Easy to amend, by the same process as ordinary laws.

Step-by-step solution:

1. The key word is "flexible," meaning easily amended.
2. Option D (rigid) is the direct opposite, so it is eliminated.
3. Option C (written) is typically associated with rigidity, so it is eliminated.
4. Option A (state) is not a classification based on flexibility, so it is eliminated.
5. Option B (unwritten) matches, since unwritten constitutions, like the British one, are typically flexible.
6. Option E is not needed because B fits.

Answer: B. unwritten.

Exam tip: Remember the pairing: Written = Rigid and Unwritten = Flexible. In NECO, JAMB, and WASSCE, if you see "flexible," think "unwritten" (Britain), and if you see "rigid," think "written" (USA, Nigeria). Note that this is a general tendency, not an absolute rule, but it is what examiners expect.
