Respuesta :
the answer would be c. because the doctor did see the assasination
The correct answer is D) a newspaper article written by a reporter who was in the audience at Ford’s Theatre.
A newspaper article written by a reporter who was in the audience at Ford’s Theatre would be considered a secondary source about the assassination of Abraham Lincoln.
A secondary source is that kind of source form people who were not present during an event or an incident. These people did not witness what happened. Most of the secondary resources are books or articles written in newspapers or magazines. In this case, the newspaper could be a great secondary source to know more details or different aspects of what happened the day President Abraham Lincoln was assassinated.
