Passage Summary: Zachary argues for stripping all non-fresco paint from the Sistine Chapel to reveal Michelangelo's true vision. Stephen points out that Michelangelo's contemporaries frequently added their own extra paint to their work after the initial frescoing was done.

Reasoning: Zachary claims that to restore an artist's intent, one must strip away everything but the paint applied to wet plaster; Stephen adds that artists of that era often added their own details to dry plaster.

Analysis: In this Most Strongly Supported task, we treat the premises as facts to see what they collectively imply. If Stephen is correct that artists added dry-paint details to their own frescos, then Zachary's plan to strip everything except the 'original fresco' would actually remove some of the artist's own intended work. The gap here is between the technical definition of a 'fresco' and the broader 'intent of the artist.' Look for an answer that concludes that Zachary’s restoration method would likely fail to preserve the full extent of Michelangelo's original vision.
