A museum has been offered an undocumented statue, supposedly Greek and from the sixth century B.C. Possibly the statue is genuine but undocumented because it was recently unearthed or because it has been privately owned. However, an ancient surface usually has uneven weathering, whereas the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface. Therefore, the statue is probably a forgery.Which of the following, if true, most seriously weakens the argument?
【选项】An allegedly Roman sculpture with a uniform surface Similar to that of the statue being offered to the museum was recently shown to be a forgery.
