Passage Summary: Deborra thinks photos don't help us understand things because photos are just still images. She believes true understanding comes from seeing how things work over time, which requires a story or narrative, not a single frozen moment.

Conclusion: Still photography is incapable of providing a true understanding of the world.

Reasoning: Understanding requires analyzing functions that occur over time, whereas still photography only captures static images.

Analysis: Deborra's argument relies on a strict divide between 'images' and 'narrative.' She claims only narration enables understanding because functions happen in time. For her conclusion to hold, she must assume that a still photograph is incapable of narrating or explaining these functions. If a photo could somehow convey a narrative or explain a function, her premise that 'only that which narrates' works would no longer exclude photography. Look for an answer that confirms still images cannot provide the narrative required for understanding.
