[問題] 一道邏輯的題目
剛剛在做題目，碰到問題，請高手解答
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.
