Downzoning, zoning that typicallyresults in the reduction of housing density, allows for more open space in areas where little water or services exists.

A) little water or services exists

B) little water or services exists

C) few services and little water exists

D) there is little water or services available

E) there are few services and little available water

正确答案E，可为什么C不对？谓语动词就近由little water决定用单数，不对吗？

AlienX

X and Y如果是表示兩個東西, 複數
X or Y的單複數是看Y.
