Correct answer: D. To build understanding and agreement
Explanation: The direct answer is D, to build understanding and agreement. In the broader meaning of democracy, people do not merely vote; they listen, express different views, discuss reasons, and try to reach a fair and peaceful decision. The reasoning is: people may begin with different opinions; dialogue lets them explain and understand those opinions; debate tests ideas and reveals concerns; respectful discussion can then produce common ground, agreement, or a workable decision. Option A, to defeat others, treats discussion as a competition and is not the democratic purpose. Option B, to spread fear, is opposite to free and respectful participation. Option C, to hide decisions, rejects openness and accountability. Option D is correct because understanding differences and building agreement are central to peaceful democratic decision-making. Agreement does not always mean that every person gets exactly what they first wanted; it can mean accepting a reasoned, fair solution after discussion. Exam cue: dialogue and debate in democracy are linked with listening, conflict resolution, participation, and consensus, not domination.
