OG11-52 关于主谓一致

52.      While all states face similar industrial waste problems, the predominating industries and the regulatory environment of the states obviously determines the types and amounts of waste produced, as well as the cost of disposal.

(B)         each state faces a similar industrial waste problem, their predominant industries and regulatory environment obviously determine
                

(C)         all states face a similar industrial waste problem; their predominating industries and regulatory environment obviously determines
                

(D)         each state faces similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determines
                

(E)         all states face similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determine
            

我的问题：主语是“the predominant industries and the regulatory environment of each state ”即两个中心词“industries and environment”，前者是复数，后者是单数。按照主谓一致就近原则的要求，谓语应该跟后一个主语“environment”才对啊，即谓语“determine”为单数“determines”，为什么这里谓语是复数形式呢？想不通，请大家解答。

谢谢！

就近原则用于or,nor

这样子啊,谢谢,看来我从初中就没有学好啊。
