Q.1 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 hypothesis 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.
What should be the answer of this question
I want to know the reasoning behind the correct answer also.
