Like the Lange's Iconic Photograph assessment, this question asks students to engage in sourcing, contextualization, and corroboration. To successfully complete this assessment, students must consider key aspects of the photograph's reliability and think about other information that could be used to evaluate the reliability of the document. In question 1, students must explain that the fact that the purpose of the Signal Corps was to produce materials that could be used to win support for the war effort calls the reliability into question. In question 2, students should identify another piece of information that would help them evaluate the reliability of this photograph.
