Select a topic such as affirmative action, abortion, or immigration, and compare public opinion on it from at least 20 years ago versus the present using Gallup polls or other public-opinion polls. Has public opinion on the issue changed over time? If so, how? (Note: You can search for actual poll data, but you might find it easier to search for news articles about poll data trends.) Each part of the prompt is fully addressed, and the student has insightful comments to contribute to the discussion. Posting length is appropriate (at least 2 good paragraphs).
