The right answer is: Facts and details. We must read the sources critically instead of just checking them out for information. In each document, you will have to identify the author, the target audience, their point of view, the people and everything that has influenced them, and their credibility. Underline the key phrases, take notes in the margins and check them when you write the essay.
A document-based essay shows how the theme under discussion relates to the time period of your attention. The purpose of writing it is for you to study the documents your professor gave you to learn and communicate an important idea about history. The writing is evidence founded so it tends to prove a point and for that you need facts and details (option A).
