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

选项是否正确?

Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.有一些F是外星来的,那可以通过判断others F来判断地球地情况,无法Weaken

题干的逻辑链是 ‘ the discovery'给了地理学家一个测试案例,用于评估这些fullerenes 形成时的地球地壳状态的假设。
一些fullerenes能够在meteorite和spacecraft碰撞时形成. 也就是说并不是从shungite 的裂缝中形成的。但是因为是部分,所以部分削弱。保留。

即使F在其他地方找了也不影響,說明都是同樣的條件,除非說明這兩個條件是不一樣的

同类不同个,研究地球有没有水,去讲火星上发现水无关;其他陨石上发现了不代表地球环境中没有。
