Final answer:
An epilogue-like section at the end of each scene, akin to a Summary Note, (option c) provides a summary and updates in non-fiction educational material, distilling information, including key terms, and preparing the reader for upcoming content.
Step-by-step explanation:
What appears at the end of each scene as a summary and update telling the reader what is going on inside and outside the annex appears to be a device reminiscent of an epilogue, but within the context of the question, it might be more appropriately referred to as a Summary Note or a transition statement. An epilogue is traditionally used at the end of a literary work to bring closure to the story, often projecting into the future to let readers know what happens to the characters after the main story ends.
In the context of a textbook or another non-fiction educational material, end-of-chapter summaries play a similar role by distilling the information presented in each section and preparing the reader for the content to come. These summaries often include key terms with definitions in context, review questions, and sometimes reflections on the material's relevance to real life, drawing connections and concluding the section with a sense of completeness.
