问题 Fresh water supplies in Asia and south America is disappearing as the glaciers melt away. [br] Cryosat should help figure out what is happening at the West Antarctic fringe because its radar altimeters should be able to ______.
选项
答案 map the steep slopes at the coast
解析 根据题干中的信息词Cryosat和radar altimeters定位到第二个小标题下的倒数第三段，可知Cryosat应该有助于确定南极西部边缘的现状，之前ERS1和ERS2上的雷达测高计都无法绘制出海岸边陡坡的地图，而Cryosat的设备则可以应付咳问题，由此可得答案。
