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.
Well I can eliminate the last one right, why would they want to lose money? I’d say it’s the 3rd one because who had more say on what happens with their company? If it’s incorrect I’ll straight up delete this unlike a lot of other people.
