求助OG紫皮的88题~

88. Down-zoning，zoning that typically results in the reduction of housing density, allows for more open space in areas where little water or services exist．

(A)  little water or services exist

(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

Diction + Agreement

In this sentence，the adjective little correctly modifies the noun water because water is not a countable quantity．However, the noun services is a countable quantity and must be modified by few，not by little．Logically, the areas described would suffer from both tithe water and few services at the same time，so the correct conjunction is and, not or This compound subject requires a plural verb．

A  Services should be modified by few not little．

B  Singular verb exists does not agree with the plural subject services；when a compound subject is joined by or, the verb agrees with the closer subject．

C  When a compound subject consists of two distinct units joined by the conjunction and, the verb must be plural．

D  Little cannot modify services．

E  Correct．In this sentence，few correctly modifies services；and correctly joins services and water．

The correct answer is E．

不是并列几物间否定时要用or吗？E选项中用的是and呀？？难道GMAT里面在这方面对and和or没有特别区分吗？
