Passage Summary: It is hard for film historians to know how early 20th-century audiences actually felt about movies because ticket sales only show money, not emotions, and reviews don't provide much help either.

Reasoning: Box office figures only track financial success rather than specific emotional reactions, and print reviews are similarly unhelpful for understanding the average viewer's experience.

Analysis: Since this is a 'Most Strongly Supported' question, we must treat the premises as facts and find a statement that logically follows from them. The stimulus highlights a specific information gap: we have data on a film's success, but we lack data on the audience's internal emotional states. Look for an answer choice that emphasizes the difficulty of using commercial success as a proxy for specific audience feelings like fear or joy. We are essentially looking for a synthesis of why these historical records are insufficient for the historians' goals.
