单选题 It is very difficult to prove today that a painting done two or three hundred years ago, especially one without a signature or with a questionably authentic signature, is indubitably the work of this or that particular artist. This fact gives the traditional attribution of a disputed painting special weight, since that attribution carries the presumption of historical continuity. Consequently, an art historian arguing for a deattribution will generally convince other art historians only if he or she can persuasively argue for a specific reattribution.
Which one of the following, if true, most strongly supports the position that the traditional attribution of a disputed painting should not have special weight?

A、 Art dealers have always been led by economic self-interest to attribute any unsigned paintings of merit to recognized masters rather than to obscure artists.
B、 When a painting is originally created, there are invariably at least some eyewitnesses who see the artist at work, and thus questions of correct attribution cannot arise at that time.
C、 There are not always clearly discernible differences between the occasional inferior work produced by a master and the very best work produced by a lesser talent.
D、 Attribution can shape perception inasmuch as certain features that would count as marks of greatness in a master's work would be counted as signs of inferior artistry if a work were attributed to a minor artist.
E、 (E) Even though some masters had specialists assist them with certain detail work, such as depicting lace, the resulting works are properly attributed to the masters alone.

【正确答案】 A

【答案解析】[解析] 根据题中的论述可知，传统归属法有其内在的弊病。一旦一幅未签名的画被归属于某人时，别的艺术历史家就很难说服别人这幅画不是那个人的作品。而艺术商们又经常受自我利益所驱使，他们会把任何未签名的绘画归为一个知名的大师的作品，而用传统归属法又很难证明这些画不属于那些大师们。因此传统归属法的有效性就得到了极大的削弱，所以(A)最能支持不应给予传统归属有争议绘画方法以太多份量的立场；(B)、(C)、(D)和(E)均为无关选项。
