Question

because they penetrate the visible surface of a painting, ultraviolet and other nonvisible spectra of light enable the detection of otherwise imperceptible features of the work. beneath the surface of claude monets wisteria (1917 - 20), art historians found that monet had initially included water lilies but ultimately painted over them. furthermore, nonvisible spectra can be used for chemical analysis to identify specific pigments and thus, in some cases, reveal forgeries: if, for example, titanium oxide—which wasnt developed until the 20th century—is evident throughout the layers of a painting attributed to an 18th - century artist, that work can only be a forgery. what does the text most strongly suggest about how analyzing a painting with nonvisible light can inform a judgment about who that painting is attributed to? a it can provide new information about the attributed artists practices. b it can definitively undermine that attribution. c it can confirm that attribution with a high degree of confidence. d it can show how the work is similar to others attributed to the same artist.

Explanation:

The text describes how non - visible light spectra can reveal information about a painting such as the use of certain pigments not available at the time an artist was active, which can help in determining if a work is a forgery. This means non - visible light can provide new information about the attributed artist's practices. For example, the presence of titanium oxide (a 20th - century pigment) in a supposed 18th - century work indicates forgery.

Answer:

A. It can provide new information about the attributed artist's practices.
