Which of the following films or clips seen in the module could be considered purely expository in form?

The film "March of the Penguins" is considered purely expository in form because it primarily aims to inform and educate the audience about the life cycle and behaviors of Emperor penguins. The structure of the film focuses on delivering information through a narrative that explains the penguin's environment, their reproductive habits, and the challenges they face in their natural habitat. The use of a voice-over narration further enhances its expository nature, guiding viewers through the visuals and ensuring that the film remains centered on factual content rather than emotional storytelling or artistic interpretation.

In contrast, other films like "High School," "Paris is Burning," and "Nanook of the North" incorporate more subjective elements, character-driven narratives, or artistic expressions that move beyond merely presenting information. These films may indulge in personal stories, social commentary, or stylistic choices that evoke emotional responses, which distinguishes them from the purely expository aim of "March of the Penguins."
