问题 Flooding is the most destructive weather disaster in the last hundred years.
To judge how serious a flood is, we have to consider the volumes of rivers and streams in an area and ______.

选项

答案the land’s absorbency

解析 第5个小标题Severity of a flood部分的第1、2、3句:The severity of a flood depends not only on the amount of water that accumulates in a period of time,but also on the land’s ability to deal with this water.AS we’ve seen,one element of this is the size of rivers and streams in an area.But an equally important factor is the land’s absorbency.空白处需要名词性成分。题目中的To judge how serious is与本段第1句中讲到的The severity of a flood depends on意思相同,原文第2句和第3句中的one element of this和an equally important factor则点明了其与第1句之间的关系。题目要求找出另一个决定因素,故答案为第3句中的an equally important factor的具体所指。
