问题 What will happen in the middle of the 21st century, if we consume resources much faster than their replacement?
In sustainable communities, rainwater is regarded as ______.
选项 A、a replacement for drinking water
B、a fertilizer to enrich soil
C、renewable resources
D、a waste product
答案C
解析 由题干中rainwater可定位到第一个小标题下第七段第二句Instead of treating normally perceived waste products such as rainwater and sewage as pollution to be gotten rid of，residents turn them into resources．该句指出，以前人们将雨水等按污染物处理，现在居民们变废为宝，将其变为资源。可知C)为正确答案。
