问题 It can be inferred from the first paragraph that
What problem did the Intergovernment Panel on Climate Change meet when they studied the earth atmosphere?

选项 A、They found the cloud’s reaction to the carbon level of the atmophere was too complex to predict.
B、They were puzzled by the carbon levels in the atmosphere’s cloud.
C、The atmosphere’s reaction to the carbon level’s raise is more diffcult to predit than they ever thought.
D、Too many uncertainties in the atmosphere’s carbon level are to be reduced.

答案C

解析 本题是细节题。根据题目顺序定位于第三段。第四句提到:他们在探索大气基础物理和化学时有了意想不到的发现:大气——特别是云层——对碳元素水平升高的反应比他们原来想得要复杂得多、难测得多。[C]为答案。[A]、[B]是对本句的曲解,[D]是对问题带来的后果的曲解,均排除。
