How can the need for a constitution be explained in one sentence?

Correct answer: It gives the country shared rules and keeps government within limits of rights.

Direct answer: A is correct. A constitution is the basic set of rules for running a country. First, it explains how the government will be formed and how public power will be used. Second, it defines the rights of citizens, so the government cannot normally act as it wishes against them. Third, it provides common rules that apply to institutions and citizens, helping people with different interests live together peacefully. Option A is correct because it includes both shared rules and limits on government power. Option B is wrong because festivals are cultural matters, not the central purpose of a constitution. Option C is wrong because democracy requires citizens to have a role in choosing and evaluating government. Option D is wrong because constitutional limits are meant to reduce arbitrary rule, not increase it. Memory cue: Constitution means “common rules plus protected rights.”
