Final answer:
Option 4, 'They lived happily ever after,' is not a setting. It is an ending of a story and does not describe a time or place, which are the components necessary to define a setting in literature.
Step-by-step explanation:
The question asks which of the following is NOT a setting:
- Long ago, in a kingdom far away...
- Once upon a time, in a galaxy far, far away...
- It was a dark and stormy night.
- They lived happily ever after.
A setting in literature refers to the time and place in which a story takes place. Options 1, 2, and 3 all describe a time and location, thus they can be considered settings. In contrast, option 4, 'They lived happily ever after,' does not describe a time or place, but rather details an outcome or ending of a story. Therefore, it is NOT a setting.
