Full Answer
Scope refers to the breadth and complexity of the central concern of your paper, including all of the points that you must establish for your readers to understand your central concern, as well as all of the significant issues that you must address in order to present a fair, well-considered argument.
Narrowing your scope helps you to write more. If your scope is too wide, the paper will be filled with sweeping generalizations. If you only scratch the surface, you will fall short of the page limit .
Flexibility is the key to determining scope.
