1. (24179-!-item-!-188;#058&000705) Althoughfullerenes--spherical molecules made entirely of carbon--were first found inthe laboratory, they have since been found in nature, formed in fissures of therare mineral shungite. Since laboratorysynthesis of fullerenes requires distinctive conditions of temperature andpressure, this discovery should give geologists a test case for evaluatinghypotheses about the state of the Earth's crust at the time these naturallyoccurring fullerenes were formed. Which of thefollowing, if true, most seriously undermines the argument? (A) Confirming thatthe shungite genuinely contained fullerenes took careful experimentation. (B) Some fullereneshave also been found on the remains of a small meteorite that collided with aspacecraft. (C) The mineralshungite itself contains large amounts of carbon, from which the fullerenesapparently formed. (D) The naturallyoccurring fullerenes are arranged in a previously unknown crystallinestructure. (E) Shungite itselfis formed only under distinctive conditions.
做第一道题就没选对。OA 是D, 我选了E..
有人可以帮忙分析下吗?
