107. Downzoning, 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 答案是e,og的解释中说 since water and services are being discussed as a pair, they should logically be treated as a compound subject requiring a plural verb; thus, the singular verbs exists (in B and C) and is (in D) are wrong.很难判断water and services are being discussed as a pair, 看了语法区的讨论,还是不很明确,拿来这里大家在讨论讨论吧
