Each writer wrote an imaginative essay answering this question:
For 24 hours, you have amazing magical powers you can use to do good. The only catch? Your powers work on just one person at a time. Will you manage to help the entire world before your time runs out? Or will you be forced to pick and choose? Explain what you'll do, what might go wrong, and how you'll work things out.
