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 shungite genuinely 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 occurring fullerenes are arranged in a previously unknown crystalline structure.
(E) Shungite itself is formed only under distinctive conditions.
答案D
這怪了,想很久還是想不通
題目說fullerenes雖然是在實驗室被發現的, 他也在大自然中某種稀有礦中被發現....
既然在實驗室裡要合成這個東西得在一個非常極端的條件溫度和壓力下,這給了地質學家一個例子去檢驗假設-->假設地殼是在fullerenes形成時自然產生的
原本選了B, 因為以為可以用"其他狀況也可以產生fullerenes"來weaken,但後來想通這是錯誤答案,some fullerences在流星和太空船撞在一起時產生,正好符合原文提到的"distinctive condition"
老實說,我看不太懂D的意思,所以不敢選d.....
可以請大家幫忙嗎?
