C: 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.
B: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.

推测:voles一般生崽是在秋天到冬天,过了冬天就会有小voles死亡
选项分析:选E
A) opposite answer,如果春天到早秋young voles多的话,就不会live in small group
B) 提上说的是不同季节vole的数量不同,并不是说year,无关
C) 题上说的size不同是和young voles的死亡率有关,如果因为plants不够,那就不光是young voles死了
D) 同C,温度也会导致adult voles死亡,不光是young
E) 蛇在春天到早秋出没,所以young voles的数量在这个时间段会减少
