Step 1: Analyze the question The question asks why public opinion is essential in a democracy. We need the option that describes a positive, democratic function of public opinion.

Step 2: Explain the concept Public opinion is the collective views, attitudes, and beliefs of citizens on political issues, government policies, and leaders. In a democracy, government derives its authority from the people, so citizens' views must be heard and considered. Public opinion:

• Keeps the government accountable
• Guides policy-making
• Restrains abuse of power
• Gives feedback on how government is performing

Step 3: Evaluate each option

• A. Check on leadership and government activities: Correct. When people express views through the press, protests, petitions, elections, and opinion polls, leaders are pushed to act responsibly and in the public interest.
• B. Mouthpiece for the opposition only: Wrong. Public opinion belongs to all citizens, not only opposition parties.
• C. News outlet for the media and government only: Wrong. Public opinion is not a news outlet, and it is not limited to the media and government.
• D. Propaganda tool for the government at all material times: Wrong. Propaganda is one-sided information pushed by the government to shape opinion, which is the opposite of what public opinion does in a democracy.

Step 4: Answer

Exam tip: In Government questions about the role of public opinion, public participation, or the press, look for words like "check," "accountability," or "feedback." Options with absolute words like "only" or "at all material times" are usually wrong.
