Like the Lange's Iconic Photograph assessment, this question asks students to engage in sourcing, contextualization, and corroboration. Students are asked to consider how the content of the two photographs could affect their reliability. Then, students must think of something else they would like to know about the circumstances of the photographs in order to further evaluate the reliability of the photographs.
