Test13/S1/Q 24. Until recently it was thought that ink used before the sixteenth century did not contain titanium. However, a new type of analysis detected titanium in the ink of the famous Bible printed by Johannes Gutenberg and in that of another fifteenth-century Bible known as B-36, though not in the ink of any of numerous other fifteenth-century books analyzed. This finding is of great significance, since it not only strongly supports the hypothesis that B-36 was printed by Gutenberg but also shows that the presence of titanium in the ink of the purportedly fifteenth century Vinland Map can no longer be regarded as a reason for doubting the map’s authenticity.
The reasoning in the passage is vulnerable to criticism on the ground that
(A) the results of the analysis are interpreted as indicating that the use of titanium as an ingredient in fifteenth-century ink both was, and was not, extremely restricted
(B) if the technology that makes it possible to detect titanium in printing ink has only recently become available, it is unlikely that printers ore artists in the fifteenth century would know whether their ink contained titanium or not
(C) it is unreasonable to suppose that determination of the date and location of a document’s printing or drawing can be made solely on the basis of the presence or absence of a single element in the ink used in the document.
(D) both the B-36 Bible and the Binland Map are objects that can be appreciated on their own merits whether or not the precise date of their creation or the identity of the person who made them is known.
(E) the discovery of titanium in the ink of the Vinland Map must have occurred before titanium was discovered in the ink of the Gutenberg Bible and the B-36 Bible
The answer is A, 我认为C好一些。
选A的not extremely restricted 是否指the famous bible printed by Johannes, 而extremely restricted 是否指not in the ink of any numerous…books.
但是看完提干后的第一感觉是怎么能因为一种墨水出现在JG印的famous bible 和另一种bible – B36, 就推论B36是JG印的？C说出了这一点，不能仅凭是否出现某一种元素来判断书和画的印刷时间和地点。C唯一的不足是他又一个Location, 在文中没有出现。但是总体感觉比A好。
不知道是我没发现更重要的东西还是什么别的原因， 请指教， 谢谢。
Cranberry 解答向下翻...
