Question 116·Medium·Inferences
At the Bellamont Museum, a painting attributed to 19th-century artist Lidia Rossetti underwent conservation analysis. Infrared reflectography revealed an underdrawing that matched sketches from Rossetti’s notebook. X-ray fluorescence of the topmost paint layers detected titanium white and phthalocyanine blue—pigments that did not become commercially available until decades after Rossetti’s death in 1890. These pigments were concentrated in the sky and around the artist’s signature. Museum records note an extensive cleaning and toning treatment performed in 1952. Thus, it is most reasonable to infer that ______
Which choice most logically completes the text?
For inference questions, list the concrete facts (especially dates, where evidence is located, and any historical records), then choose the conclusion that most directly follows without adding speculation. Eliminate choices that (1) contradict stated evidence, (2) invent unmentioned explanations, or (3) make an overly extreme claim compared with what the passage supports.
Hints
Notice what the underdrawing shows
What does it suggest if the underdrawing matches sketches known to be Rossetti’s?
Focus on the pigment dates
If a pigment wasn’t commercially available until long after 1890, what does that imply about when paint containing it was applied?
Use the museum record
How could a documented 1952 cleaning/toning treatment explain modern pigments appearing in only certain areas?
Eliminate extreme or unsupported claims
Watch for choices that go further than the evidence (for example, claiming the whole work is fake or claiming the science is wrong without any support).
Step-by-step Explanation
Collect the key factual clues
Key details from the passage:
- The painting’s underdrawing matches Rossetti’s notebook sketches, supporting that the original work traces to Rossetti.
- The topmost paint layers contain titanium white and phthalocyanine blue, which were not commercially available until decades after Rossetti’s death in 1890.
- These pigments are concentrated in the sky and around the artist’s signature.
- Museum records note an extensive cleaning and toning treatment in 1952.
Use the pigment dates to infer timing
Because the identified pigments were not commercially available until well after 1890, any paint containing them was most reasonably applied after Rossetti’s death, not during her lifetime.
Link where the pigments are found to the 1952 treatment
The modern pigments appear in specific visible areas (the sky and around the signature), and the museum records describe a major 1952 cleaning/toning treatment. It is therefore reasonable to infer that those particular areas were retouched or repainted during (or as part of) that later treatment.
Select the choice that matches the supported inference
The best supported conclusion is: parts of the sky and the area around the signature were repainted decades after Rossetti’s death, likely during the 1952 treatment.
