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
这里each state 和all states有什么区别,OG里说“Each state must be compared to all other states”是什么意思?没看明白~~~~
是不是因为这句话逻辑上强调的是整体概念,即所有州都遇到了相同的问题,而每个州的predominant industries 和 regulatory environment 影响到的是全国的types and amounts of waste produced 如果用each state的话,强调的可能只是每个州自己内部的问题,而跟全国没多大关系了?
