问题 Original usage refers to rivers that ______ . [br] Entering rivers by ______ , phosphates and nitrates as fertilizers can result in eutrophication.
选项
答案 rainwater runoff and groundwater seepage
解析 该段第一句指出用磷酸盐和硝酸盐做肥料能够引起其他问题。第二句就举例说明了所导致的问题。该句中的Entering rivers via rainwater runoff and groundwater seepage, these chemicals can cause eutrophication直接给了导致超营养作用的是Entering rivers via rainwater runoff and groundwater seepage，其中by=via。
