刚好听了17
发现calcite deposits(1980)是导致researcher认为和之前的hypothesis contradict
而1990的new evidence证明的是Devils Hole reveal only the local climate, but not global climate.
所以C从这两个方面都是不对,calcite deposits没有直接证明devild hole reveal the local climate. 并且climate changes occur only locally错误解释了原文的意思。(Fact is climate changes occur globally, but Devile Hole only reveal the local climate.)
