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 .

b) 无关。15世纪的artist知道ink里是否含有titanium和文章的批驳无关
c) 观点好象很主观。。根本没有批驳原文的论证。。只是说unreasonable
d) 无关。。 圣经和图都需要在知道了确切时间后才能被鉴赏。。
e) 无关.和发现含有titanium时间无关.
