How can readers tell that this text is a secondary source?

Question

It does not have personal stories.
It has photographs and drawings.
It has an interview with an immigrant.
It does not have general knowledge.

Answer 1

Readers can tell that the text is a secondary source primarily because it does not have personal stories. Secondary sources typically analyze, summarize, or interpret information from primary sources rather than presenting firsthand accounts or original research. The presence of personal stories would suggest a primary source, while the lack of them indicates it is likely synthesizing information gathered from other works.
