确定选A是正确的，这是PREP2007的原题哇~
(A)正确,两个动词returns和contributes都与主语一致,并列用两个并列的句子清晰的表现了降水回归自然的两种途径.
(B)主谓不一致,the remainder应该用单数谓语形式,contribute应该改为contributes; flow本身就是名词形式,不需要用the flowing来表现名词形式.
(C)主谓不一致,return应该改为returns,同时contribute应该改contributes;the flowing应该改为the flow.
(D)介词with后面不能跟不定式to do,并且将两个并列成分改变为主从成分,从而改变了原句的意思.
(E) as使用有误,句子本意并不是对两个动作进行比较,而是称述两个事实;主谓不一致:return和contribute均要改为单数形式.
