In the mid-twentieth century, the development of the *strappo* technique allowed art conservators to peel the topmost pigment layer of deteriorating Renaissance frescoes from church walls, inadvertently revealing the underlying preparatory charcoal drawings known as *sinopie*. Early conservators assumed that because *sinopie* were executed directly onto the rough plaster (*arriccio*) prior to the application of the final smooth plaster layer (*intonaco*), they represented the master artist's unmediated, purest compositional intent. However, recent physical analysis indicates that *sinopie* frequently incorporate proportional grid marks and geometric calculations executed using workshop assistants' pigments rather than the master's characteristic mineral inks. Furthermore, because the subsequent *intonaco* was applied in daily sections (*giornate*) that physically obscured the underlying *sinopia*, painters working on the final pigment layer often had to rely on portable paper sketches (*cartoni*) rather than directly following the covered preparatory drawing.
Which of the following statements is most strongly supported by the information in the passage?
- AThe *strappo* detachment method was initially developed specifically to uncover and preserve preliminary *sinopie* drawings.
- BWorkshop assistants typically determined the overall thematic composition of a fresco before the master painter began work on the *arriccio*.
- The visual content of a *sinopia* was not continuously observable to artists throughout the entire process of applying final pigments to the *intonaco*.Answer
- DThe physical application of the *strappo* technique permanently degraded the chemical stability of the master artist's mineral inks.
- EPortable paper sketches were exclusively utilized when a master artist worked entirely without the aid of workshop assistants.
