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 occurring fullerenes were formed.

which of the following, if true, most seriously undermines the argument?
A.confirming that the shungiye geniunely contained fullerenes 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 ocurring fullerenes are arranged in a previously unknown crystalline structure.
E.shungite itself is formed only under distinctive condition.

这是官方模考软件上面的一题,不过我没看懂是什么意思,请教高手啊~~~~
PS:今天第一次做模考,数学错了5个,语文错了18个....竟然还有650分....完全不知道情况,希望考过的高人提点下.主要是下个星期就要考了.....心里还完全没有底啊,谢谢啦

D

一种碳化合物首先在实验室中制造出来，然后被发现在天然矿物中也有。由于在实验室中制造需要特殊的温度压力条件，因此可以评估天然存在这种化合物的地方形成这种化合物时的物理状态条件。要求找出削弱项。

D的意思是：自然界中的这种物质的晶体结构和实验室中制造的这种物质的晶体结构不同（未知的晶体排列方法）。
