Which of the following is an example of a secondary source? a. the diary of anne frank b. a letter written to marc antony from julius caesar c. a documentary film about the murder of medgar evers based solely on first hand accounts of his life d. a series of correspondence between former united states presidents thomas jefferson and john adams

secondary sources are: books, newspapers, pamphlets and encyclopaedias. Secondary sources involve generalization, analysis, synthesis, interpretation, or evaluation of the original information so i would say D. a series of correspondence between former United States presidents Thomas Jefferson and John Adams

It would most likely be D, but I could be wrong.
