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.
(A)all states face similar industrial waste problems, the predominating industries and the regulatory environment of the states obviously determines
(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
题目分析：A中是predominating industries和regulatory environment进行并列，不能用determines，干掉（顺便说一个经验，当划线的头和尾用的是动词的时候常常考主谓一致这个知识点）B前面用each state但是后面用their predominant industries前后不一致，干掉。C也用determines，犯得错误与A一样。D也是determines，只有E没有犯前几个选项犯的错误，留着。
