问题 Antarctica is scientifically important in that ______.
When the author calls Antarctica "distant-early-warning sensor", he actually means that ______.
选项 A、such equipment has been set up for scientific purpose
B、the research groups there are like such kind of sensors
C、potential global changes can be seen on Antarctica first
D、Antarctica is remote from other parts of the earth
答案C
解析 作者意图理解题。从文章中第二段第一句"…see Antarctica as a distant-early-warning sensor，where potentially dangerous global trends may be spotted before they show up to the north."我们知道在南极洲可以观测到一些潜在的全球危险趋势。此意正好与选项C的意思吻合，故选项C正确。
