Final answer:
A documentary film that includes interviews with orphans and analyzes them contextually is considered a secondary source containing primary source material.
Step-by-step explanation:
The distinction between primary and secondary sources is crucial in historical analysis. A primary source offers an immediate, first-hand account from the particular time period under study, whereas a secondary source provides interpretation and analysis of primary sources. Considering a documentary film that includes interviews with actual orphans, we can understand that it might be a primary source for studying the orphans' personal experiences at the time they are interviewed. However, if the film also interprets and contextualizes those interviews as part of a broader historical analysis, then it also functions as a secondary source. Thus, in this context, the most accurate statement about the documentary film is that it is a secondary source that contains primary source material, since the interviews are primary sources but the film itself, which interprets these and likely other primary source materials, is secondary.
