First find a topic that is currently in the news and provide some brief background (the who, what, when, where, and how of the topic). Then continue your summary by explaining the positions others hold on the topic. What do the true believers of the issue think? What do the ultimate doubters have to say?
Finally, what is your position on the issue? Remember: The best topics aren't just focused on pro/con debates. Though this activity asks you to look at the extreme sides of the issue, your opinion might fall somewhere in the middle or contain elements of each side. However, you must express a position with which someone could reasonably disagree.
