The following text is about art restoration.
Cleaning a centuries-old painting is far more complex than it might seem. Restorers must carefully remove layers of accumulated dirt and discolored varnish while preserving the original paint beneath. Modern technology like spectral imaging helps identify which layers were added by later hands. When done correctly, restoration can reveal colors and details that had been hidden for generations, transforming our understanding of a masterpiece.
What is the main idea of the text?
Art restoration is a challenging process that can reveal hidden aspects of artworks
Old paintings should never be cleaned or restored
Spectral imaging was invented specifically for art galleries
All painting varnish should be removed immediately
Correct Answer: A
Choice A is the correct answer. The text describes the complexity ("far more complex") and the potential to "reveal colors and details that had been hidden."
- Evidence: Discusses challenges and potential discoveries.
- Reasoning: Both difficulty and benefits are presented.
- Conclusion: Complex but rewarding process is the main idea.
Choice B is incorrect because the text supports careful restoration. Choice C is incorrect because the text only says imaging "helps," not its origin. Choice D is incorrect because the text emphasizes careful decision-making.
