题目选项分析

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?

【选项】Shungite itself is formed only under distinctive conditions.

选项是否正确?

無關,S如何形成跟F如何形成沒關係

无关。,SH是形成FU的一种原始要素,该要素仅在特殊环境中形成,与形成FU的地球环境无直接关系。可能SH形成了很多年了,FU才形成,故该条件无关。

S和F无关,和能否通过实验室里F形成的条件推断自然界中F形成的条件更加无关!

S在特别的环境中形成,无法推出和逻辑链的具体关系,没有点明和F的关系

shungite为无关研究对象,且段落提及fullerence的合成条件,并非shungite
