Which is the best example of a secondary source document useful in the study of history? a letter from a relative of a participant in a battle or campaign a newspaper article written the day after an event occurred an academic analysis of key battlefield strategies an officer's listing of military personnel killed in battle

The correct answer is B.

A newspaper artcile that was written a day after the historical event would be a perfect secondary source for the study of history.

This article would provide the views of people during the time the event occurred. It would have details and information that may otherwise be unkown about the event, and it would likely have a photo of the event, which would help understand the whole story.
