What is considered a primary source?

A primary source is defined as an original document or artifact that provides direct evidence or firsthand accounts of a particular event, phenomenon, or topic. In this context, a primary source presents the story directly, without alteration or interpretation by others. Examples of primary sources include diaries, speeches, letters, photographs, and original research studies, as they allow direct insight into the subject being studied.

The other options pertain to secondary sources, which analyze, interpret, or summarize primary sources rather than providing direct evidence. Therefore, these options do not qualify as primary sources, solidifying that the correct designation is indeed the one that highlights the direct presentation of information.
