Flawed Parallel ReasoningDiff: Medium
Logic Breakdown
Passage Summary: The museum has a rule: if a piece is super fragile or super expensive, it only stays out for two weeks. Since a specific painting is only out for two weeks, the author concludes it must be one of the expensive ones.
Conclusion: The specific artwork "Spring and Autumn Maples" must be one of the most valuable items in the collection.
Reasoning: The museum displays both its most light-sensitive and its most valuable items for only two weeks; since this specific piece is displayed for two weeks, it must fall into the "valuable" category.
Analysis: This is a classic 'Mistaken Reversal' combined with a grouping error. Just because two different groups (sensitive and valuable) share a trait (2-week display), you cannot conclude a specific item with that trait belongs to one specific group—it could easily be in the other group. Look for an answer where an item has a trait shared by two categories, and the author incorrectly assigns it to one of them. It's like saying 'Doctors and lawyers both wear suits; John is wearing a suit, so John must be a lawyer.'

Correct Answer
E
E matches the flawed form: Historical monuments → purple dot; Hospitals → purple dot; There’s a purple dot on Wilson Street; therefore, it’s a hospital. That mirrors concluding ‘most valuable’ from ‘two weeks only’ even though ‘two weeks only’ could also indicate ‘light-sensitive.’
