: 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.
我試著解釋看看 解釋錯請勿見怪
原文說地質學家認為地殼中fullerenes會自然地被形成 (他也可以在實驗室中在特定條件
下 被合成出來)
A:只說實驗要很小心 --->無關
B:只說明有些fullerenes的來源 並不能因此反駁地殼無絕對無自然形成的fullerenes
C:支持
D:這些fullerenes的結晶結構前所未見:照理說地殼的各種物質結晶應該都被地質學家們
所知 而他的結晶竟然是前所未見 表示他形成的條件非常特殊 這樣的情況下某程度削
弱了地質學家的看法
E:只說必須在特定的條件下才會形成 不代表地殼無自然形成的fullerenes
: (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
