Similarities of primary and secondary source?

Answer 1

Both primary and secondary sources are both sources and both can have photographs classified in it- whether fake or real. They also both have autobiographies/biographies classified in it, but it depends whether handwritten by a particular person at a particular time.

Answer 2

Both primary and secondary sources provide information and evidence for research. However, primary sources are firsthand accounts or original materials, while secondary sources interpret, analyze, or comment on primary sources. Both are important in academic research to support arguments and provide credibility to a research paper.
