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

Choice A is best. In choice B, should is illogical after requires, or at least unnecessary, and so is better omitted; in choices B and E, job does not agree in number with jobs; and in choices B, D, and E, the wording illogically describes the comparable skills rather than the jobs as being "usually held by men." Choices C, D, and E produce the ungrammatical construction requires of... employers to pay, in which of makes the phrase incorrect. In C, the use of in rather than for is unidiomatic, and jobs of comparable skill confusedly suggests that the jobs rather than the workers possess the skills. In D, the phrase beginning regardless ... is awkward and wordy in addition to being illogical.

我选的答案是D,现在理解用不定式是不对的

但是解释说“ in choices B, D, and E, the wording illogically describes the comparable skills rather than the jobs as being "usually held by men."

为什么定语从句usually held by men的先行词是job不是skills呢?

原文的that are usually held by men.的确与jobs保持了数的一致，如果要写一个修饰skill的定语从句该怎么写呢？

而且定语从句一般是紧跟现行词的啊

请大牛们帮助解释一下
