※ 引述《amo18 (要打什麼啦)》之銘言： : 不好意思 因為傷咖上不去 : 所以有問題就只能來這裡請教了 : 想請問幾題CR的問題 : 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. : 這題找反駁 但我其實看不太出來D和原文的反駁怎麼建立的? : 我選了B 錯了 想請教 原文是說:在研究室發現fullerene的形成也許可以提供自然形成fullerene 時候的地殼環境的一個評估(翻的好爛~好難翻) 首先:(A)(C)(E)完全與weaken無關，您排除的是對的 (B)的意思是:fullerene也有在和飛行機相撞的隕石中- 這選項我覺得是無關的，因為外太空怎麼形成fullerene跟提幹(地球上怎麼形成) 是無關的。知道外太空怎麼形成我門就不能從實驗室的情況推出地殼自然形成的 state(狀態)嗎? 當然不會。所以(B)似乎是無關。 (D)選項至少比(B)更貼近提幹-(D)是說形成的結構是unknow- 所以(B)跟(D)比我會選(D) (雖然CR的答案真的有時候很怪~只能找個比較不爛的) ------------------------- -- --
