Resolution

Resolution is defined by contemporarylit.about.com as "  the part of the story's plot line in which the problem of the story is resolved or worked out. This occurs after the falling action and is typically where the story ends."

Common Examples of Resolution
When you settle an argument with someone, that's a resolution. When you reach a destination, that's a resolution. When Disney characters kiss and it says "happily ever after", that's a resolution. Resolutions are a part of everyday life.

Resolution in Lord Of The Flies
Lord of the Flies ends with Ralph and the boys getting rescued and sobbing their little hearts out. This, of course, solves the main problem of being stuck on a deserted island.
