A chain of command is an organizational system where instructions are passed from one person to another. It's widely used in military and other disciplined organizations (ex:police departments, & military ) in addition to civil organizations. So think about your local supermarkets they have regional managers, below the regional managers there are district managers ,below the district manger there is General manager then below them is a few assistant managers, below the assistant manger they have the clerks/stockers.

Fragment is the correct answer
What is the question here because I don't see it.
The correct answer that completes the list of narrative text elements is resolution. Every text needs an ending that fits the story and its conflict or problem. The resolution helps the reader to understand how the conflict was solved. Even though some stories have an open ending, there are always minor resolutions that help the reader imagine the possible ending.
