X-ray examination of a recently discovered painting—judged by some authorities to be a self-portrait by Vincent van Gogh—revealed an under image of a woman’s face. Either van Gogh or another painter covered the first painting with the portrait now seen on the surface of the canvas. Because the face of the woman in the under image also appears on canvases van Gogh is known to have painted, the surface painting must be an authentic self-portrait by van Gogh.
The conclusion is properly drawn if which of the following is assumed?
A. If a canvas already bears a painted image produced by an artist, a second artist who uses the canvas to produce a new painting tends to be influenced by the style of the first artist.
B. Many painted canvases that can be reliably attributed to van Gogh contain under images of subjects that appear on at least one other canvas that van Gogh is known to have painted.
C. Any painted canvas incorrectly attributed to van Gogh would not contain an under image of a subject that appears in authentic paintings by that artist.
D. A painted canvas cannot be reliably attributed to an artist unless the authenticity of any under image that painting might contain can be reliably attributed to the artist.
E. A painted canvas cannot be reliably attributed to a particular artist unless a reliable x-ray examination of the painting is performed.
