G-prep - fullerenes那道

Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite. Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occutting fullerenes were formed.

Which of the following, if true, most seriously undermines the argument?

A, Confirming that the shungite genuinely contained fullenenes took careful experimentation.

B, Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.

C, The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparently formed.

D, The naturally occurring fullerenes are arranged in a previously unknown crystalline structure. （D）

E, Shungite itself is formed only uder distincitve conditions.

题目说F这种东东最早在实验室中发现，但在自然界的S矿中也有。因实验室合成条件特殊，该发现就给了地理学家一个案例，可用于评估地壳在F生成时的状况。

A：关于S矿的实验很仔细，所以应该是增强

B：一些F发现自陨石，感觉有削弱，说明这玩意儿跟地壳状况无关

C: S矿含很多炭，无关

D: F在自然界结构特殊，但这也可以让地理学家研究吧，这个削弱感觉有点勉强

E：S矿本身在特殊条件下形成，不影响推理

我模考时错选了B，不是很理解考点，也可能对题目理解有误，请NN拍砖：）

D, The naturally occurring fullerenes are arranged in a previously unknown crystalline structure.

D说了这东东的情况跟学者掌握的不同,是人们不知道的,所以无从着手来根据这东东对地球做评估了.
