An unsigned painting has long been attributed to artist Lena Ortiz. A new materials analysis does not definitively disprove that attribution, but it ______ it: the canvas contains a synthetic fiber that became common only after Ortiz's death.
Which choice completes the text with the most logical and precise word or phrase?
For a Words-in-Context question, identify the claim being discussed, determine whether the surrounding evidence strengthens, weakens, modifies, or replaces that claim, and pay close attention to degree words such as “definitively.” Then select the option whose meaning and intensity most precisely match the full context.
Hints
Identify the referent
Determine what the second “it” refers to and what claim the materials analysis is evaluating.
Notice the degree cue
The phrase “does not definitively disprove” distinguishes evidence that raises doubt from evidence that conclusively settles the issue.
Consider the chronology
Ask how a material associated with a later period would affect confidence in the painting's traditional attribution.
Step-by-step Explanation
Identify the claim under consideration
The claim is that Lena Ortiz created the unsigned painting. The blank must describe how the new materials analysis affects that attribution.
Interpret the degree of doubt
The phrase “does not definitively disprove” indicates that the analysis is not conclusive. However, the word “but” signals that the evidence still creates a significant problem for the attribution.
Connect the evidence to the claim
The canvas contains a fiber that became common only after Ortiz's death. This chronological mismatch makes the attribution less credible, so the analysis “challenges” it rather than supporting, refining, or replacing it.
