Final answer:
The least likely content in a Revolutionary War soldier's journal entry would be a third-person narrative that shifts point of view, as personal diaries typically contain first-person accounts filled with personal experiences.
Step-by-step explanation:
The journal entry of a Revolutionary War soldier would least likely include option D: A third-person narrative that shifts point of view. Such a narrative style would not typically be employed by soldiers recounting their own experiences in diaries or personal letters. These historical texts are considered primary sources and often provide a first-person account filled with the writer's individual thoughts, feelings, and direct observations. The personal nature of these accounts usually reflects the intense, immediate experiences of daily life in the military during a significant period like the Revolutionary War.
Contrastingly, third-person narratives are more common in biographical or historical writings where the author is describing someone else's experiences. As demonstrated by historical writing trends, personal soldier journals would primarily feature first-person narratives, allowing the reader to grasp the writer's personal point of view.
