大全-Ⅲ-15.长句 It is true that unionized women earn, on average, more than a third more than nonunionized women do. But the unionized women work in industries where wages happen to be high, their nonunionized counterparts in these industries earn about as much as they do. Therefore unionization does not raise women’s wages.
Which of the following, if true, most seriously weakens the argument above?　　Ｃ D
(A) Besides wage increases, unions bargain for benefits such as medical insurance and workplace safety.
(B) The most highly paid women are in executive positions, which are not unionized.
(C) Wages in many industries vary from one part of the country to another, regardless of whether workers are unionized or not.
(D) Nonunionized women in an industry often receive income increases as a result of increases won by unions representing women who work for other employers in the same industry.
(E) The unionization of women who work for one employer in a given industry frequently prompts the unionization of women who work for other employers in the same industry.
答案应该选D，可是D选项中“increases won by unions representing women who work for other employers in the same industry.”是什么意思，没有理解？

increases won by unions representing women who work for other employers in the same industry.
我觉得这句话意思是说，“在同一个工业不同公司参加工会的女工人争取到了工资的提高，所以影响到了同行业其他公司没有参加女工人的工资。”就是说一个行业女工人的工资都提高了，哪怕女员工没有参加工会，工资会跟着同行业工资一起上涨。不知道这么解释清晰不。
