109. Legislation in the Canadian province of Ontario requires of both public and private employers that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are usually held by men.
(A) that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are
(B) that pay for jobs historically held by women should be the same as for a job requiring comparable skills
(C) to pay the same in jobs historically held by women as in jobs of comparable skill that are
(D) to pay the same regardless of whether a job was historically held by women or is one demanding comparable skills
(E) to pay as much for jobs historically held by women as for a job demanding comparable skills
该题的正确答案是A,
而A中的jobs requiring comparable skill that are usually held by men中的that从句按照OG的说法修饰的是前面的jobs 而不是后面的skill，是不是仅仅因为jobs为复数而skill为单数呢？
除了主谓一致，还有别的判定跳跃修饰的办法吗？
哪位大侠能不能帮我解释一下定语从句的跳跃修饰问题，谢谢了！！
另外，OG说usually held by men的逻辑主语必须是job 而不可以是skill？如果是skill有什么不对呢？ |
