Answer:
A photograph of Theodore Roosevelt is an example of a primary source.
Step-by-step explanation:
In history, the sources that provide information of a society in a given moment in time, are divided into primary and secondary sources.
Primary sources are the best source of information a historian has since they are documents that were produced during the time of study. Documents, journals, maps, photographs, are examples of primary sources. In this case, a photograph of Roosevelt is an example of a primary source because it was taken during his life, it can provide information about his life but also about the social context of that period.
