write a 3-5 paragraph story about what causes the disaster on Disaster Day.  Was it a plane crash, hurricane or bomb blast at a disco?  Something else?  Why did it happen?  What is the initial damage?  Where does it happen?

Do not write anything about what the first responders do at the scene.  Compare it to a video trailer at the beginning of a video game.  The Narrative sets the stage and objectives.  We do the rest.

This will be a 3-5 paragraph assignment, typed.
