Final answer:
The correct answer is D. The historical dates and personal pronouns suggest that the passage is from a primary source, likely a diary entry, containing an eyewitness account of events at that time.
Step-by-step explanation:
The best clue that this paragraph came from a primary source is the inclusion of historical dates and personal pronouns. The paragraph describes specific events and actions that occurred on September 18 and 19, 1775. The use of personal pronouns, such as 'we' and 'our,' suggests that the author is directly involved in the events being described, indicating a first-hand account.
Primary sources are original documents or records that were created at the time historical events occurred. The passage provided features specific dates and uses first-person narrative ("we"), signifying a contemporaneous account of events as they unfolded, which is typical of diary entries or personal logs. The use of military titles and nautical terminology within the context further strengthens the notion that this is a personal account, likely from someone involved in military or naval operations during that period.
