求教OG11 RC第三篇的14题

Fereydoon

大家好，关于OG11的RC第三篇的14题有点不求甚解，OG的解释感觉很牵强，请哪些好心的大侠给与指点，不甚感激：

第三篇RC文章：就是讲通过出售duplicate artifact一方面提升考古学的收入，一方面curb不法盗墓，14题目如下：
The author implies that all of the following  statement about duplicate artifacts are true EXCEPT:
(A) a market for such artifacts already exists
(B) such artifacts seldom have scientific value
(C) there is likely to be a continuing supply of such artifacts
(D) museums are well supplied with examples of such artifacts
(E) such artifacts frequently exceed in quality those already cataloged in museum cllections

答案为(A)，我选择了(E)，OG的解释是“in the closing sentence of the passage, the author implies the market already exists”；但我认为这个解释很牵强，不明白原文最后一段是如何暗示这个市场已经存在了，请做过的大侠指点迷津，万分感谢！
