The correct answers are: It focuses on a female spy. It tells facts through a story. It suggests Van Lew was impressive.
Indeed, it does not use short, but actually rather long sentences, constituted of several noun or verb phrases. It also does not include exact dates it only provides a more vague historical markers (Confederate capital city, the war, the Union) that allow the reader to position the context around the time of the Civil War (1861-1865) but with no precise dates.
It obviously refers to a female spy as evidenced by the metaphor “eyes and ears”. I lists a series of accomplishments such as the organization of a spy ring (a network of agents), of which she was the organizer (spymaster) as well as the creation and organization of a network of assistance (for southern deserters and for northern POWs) and a communications network of sensitive information about the confederate military (couriers).
Finally, the fact that she was able as a woman, in an era when women were subservient to men, and during a period of civil war, to accomplish all of this does inevitably imply and openly states that she was impressive (she became much more than that).
