Conclusion: The Copper Butterfly was probably painted by the artist who died later (Artist 2).
Premise:
- Artist 1 died one week (7 days) after the painting was commissioned.
- Artist 2 died 13 years later.
- Oil paintings usually take a long time to complete.
Task: Select the option that most strongly supports the conclusion that Artist 2 painted it.
Option Evaluation
A. The artist who died later was murdered whereas the artist who died earlier passed away after contracting a disease that was plaguing the area.
Incorrect: The cause of death has no bearing on whether either artist had the time or capability to complete the painting.
B. The artist who died earlier completed a different oil painting one week before the Copper Butterfly was commissioned.
Incorrect: This might suggest Artist 1 was capable of painting, but it doesn't give concrete evidence about whether Artist 1 could finish this specific painting within the 7-day window before dying. It's too weak compared to C.
C. The oil paint used 520 years ago was produced by the artists themselves for each painting, in a chemical reaction that took eleven days to prepare.
Correct: This provides a decisive, logistical elimination! Artist 1 died just one week (7 days) after the commission. Since preparing the paint alone required eleven days, Artist 1 literally could not have even finished preparing the paint before dying, making it physically impossible for them to have painted it. This heavily strengthens the hypothesis that Artist 2 (who lived 13 years later) was the creator.
D. The artist who painted the Copper Butterfly did not paint another picture for the person who commissioned it.
Incorrect: This is irrelevant to the timeline or the identity of which of the two specific artists painted it.
E. The artist who died earlier was known for leaving his paintings unsigned.
Incorrect: The passage already states that The Copper Butterfly is an unsigned painting. Knowing that Artist 1 often left paintings unsigned does not help prove who painted this specific work within the tight 7-day window.
