Passage Summary: Professor A's tests are harder than Professor B's, so any single question on Professor A's test must be a hard question.

Conclusion: A specific question about dinosaurs must be difficult.

Reasoning: The question appeared on an exam from a professor whose tests are generally harder than another professor's tests.

Analysis: This argument contains two distinct flaws: a 'whole-to-part' fallacy and a 'relative-to-absolute' fallacy. Just because a test is harder on average (relative) doesn't mean every single question on it is difficult (absolute). We need to find an answer that concludes a specific part has an absolute quality simply because the whole it belongs to has a relative quality compared to something else.
