Answer:
A good place for reviewers to start is with:
A. an analysis of the work's context.
Step-by-step explanation:
The work of a reviewer can become really strenuous when the work is too extensive or complex, so an ideal first step is to do a context analysis, that is, not to focus directly on the object of the work but everything that led to its creation, as its historical, social, political or academic base, and all that it would involve, which can give you a general idea of the work, which you will surely use later as prior knowledge to objectively analyze the works without making mistakes like misinterpretations.
