问题 Fresh water supplies in Asia and south America is disappearing as the glaciers melt away. [br] The ice tongue growing out from the Greenland coast used to reject salt back into the water, making ______ heavier and helping it to sink.
选项
答案 the water。
解析 根据题干中的信息词ice tongue和Greenland coast定位到原文倒数第三段，可知格陵兰海域中部在夏季不会冻结，但在冬季，通常会被从格陵兰海岸延伸而出的一大片冰覆盖，这片冰会释放盐分回到水中，从而增加水的密度，并使其下沉，而自1997年以来，这块冰舌就没有再出现过，由此可得答案。
