题目：
For over two centuries, no one had been able to make Damascus blades—blades with a distinctive serpentine surface pattern—but a contemporary sword maker may just have rediscovered how. Using iron with trace impurities that precisely matched those present in the iron used in historic Damascus blades, this contemporary sword maker seems to have finally hit on an intricate process by which he can produce a blade indistinguishable from a true Damascus blade.
Which of the following, if true, provides the strongest support for the hypothesis that trace impurities in the iron are essential for the production of Damascus blades?
选项:
A、
A. There are surface features of every Damascus blade—including the blades produced by the contemporary sword maker—that are unique to that blade.
B、
B. The iron with which the contemporary sword maker made Damascus blades came from a source of iron that was unknown two centuries ago.
C、
C. Almost all the tools used by the contemporary sword maker were updated versions of tools that were used by sword makers over two centuries ago.
D、
D. Production of Damascus blades by sword makers of the past ceased abruptly after those sword makers' original source of iron became exhausted.
E、
E. Although Damascus blades were renowned for maintaining a sharp edge, the blade made by the contemporary sword maker suggests that they may have maintained their edge less well than blades made using what is now the standard process for making blades.
答案:
D

这个题目想请老师帮忙解答一下就是首先看问题说是加强一下这个假说，回到原文我说我第一遍读原文读出来的结果哈，考场上我估计也差不多，我读的结果是说好像古代有人造出的宝剑好像绝迹了还是失传了之类的，现在有人用带有ti的这种东西的铁造出来然后就跟古代的宝剑没什么区别，所以就有了假说：正是应用了ti这个东西才复原出了之前的这种宝剑，让我加强一下，我就得找一个选项跟这个假说连起来呗，ABCDE都无关都被我排除了但是时间不多了于是选了C，我后来再按照这个思路重来一遍发现确实C也无关，但是D真的一眼看不出有关来，请问一下老师这个D说这种宝剑一成品就消失了什么之类的跟假说有啥关系，请问一下老师怎么在考场上能看出D有关来的？谢谢老师
