问题 Antarctica is scientifically important in that ______.
Which of the following statements is true according to the article?

选项 A、There is a cluster of island west of the Transantartic Mountain.
B、Scientific research on Antarctica only centers on the ice and snow there.
C、Dry valleys may be a place to dispose of our pollutants.
D、All the countries on earth should be concerned about the health of the West Antarctic Ice Sheet.

答案D

解析 综合分析归纳推论题。从第三段最后一句“…the western part of the continent would be reduced to a sparse cluster of island”可知此句为条件句,用的是虚拟语气,因而选项A中的事实句不正确。从第四段第一句中,可知,冰川和神秘“干谷”都是实验的重心,故排除B选项。根据文章最后一句,可以排除C。从第二段最后一句知选项D正确。
