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?
Museums can accept a recently unearthed statue only with valid export documentation from its country of origin.
The subject's pose and other aspects of the subject's treatment exhibit all the most common features of Greek statues of the sixth century B.C.
The chemical bath that forgers use was at one time used by dealers and collectors to remove the splotchy surface appearance of genuinely ancient sculptures.
Museum officials believe that forgers have no technique that can convincingly simulate the patchy weathering characteristic of the surfaces of ancient sculptures.
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.
真品的表面往往是凹凸不平的,然而这个雕塑的表面很光滑,像是伪造者使用化学药剂来模仿真品的样子。因此,这雕塑可能不是真的。问weaken
choice b,雕塑的动作等其他特征符合16世纪希腊雕像的特征。irrelevant,没有提到光滑的表面
choice c, 伪造者一度使用的化学药品也被dealers,collectors用来移除真品表面的斑点。correct,说明chemical bath不止一个用途
choice d, 博物馆专家相信伪造者没有技术能力可以模仿古代雕塑的表面。
choice e, 一个具有光面表面的声称是真品的雕塑最近被证明是赝品。strengthen the conclusion
CD之间犹豫,最后选了D。。。。
答案A: 阐述Musuem的规章,无关
B:雕塑的姿势与6th的雕塑相似,仿品也能这么干,所以无关weak or strength
C: 造假用的chemical在仿品身上,收藏者也会用来去除污渍(X-->Y, Z--> X&Y)
D: 专家觉得造假人没有把薄膜做凹凸的手艺,文中就是说表面很平整,所以这是support了
E: 这是support了,暗示这个也有可能是假的
C. 化学处理被用来去除正品表明的脏污;化学处理过的也可能是正品,削弱结论,正确
前提:statue surface有用来模仿weathered的什么什么
结论:赝品
