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?

(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.

OA：D
明白D正确，想问问大家如何排除B的。觉得说的也很有道理的样子呀。结果选错了

Therefore unionization does not raise women’s wages.
weaken这句话，就是证明unionization对women’s wages有好处。

The most highly paid women are in executive positions, which are not unionized. 跟unionization无关

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. unionization对Nonunionized women有好处。

。。这两个词看着真混啊un-和non-，哈哈哈~~~
weaken的题是要找一个新元素或者新关系使得论证变弱。strengthen也是一样。所以bottom line是要找新元素或者新关系

B中说的没有新元素或者新关系，因此没有给整个argument任何contribution，因此argument的可信度没有变化，因此不选

谢谢Alzn，

看B的时候，本来是要找削弱的选项，不知道为啥找找就开始找加强的选项了。
看题时，还要再努力一下牢牢记住问题。明白了，thanks，

这道题看成加强题了。

谢谢你的解释，"weaken的题是要找一个新元素或者新关系使得论证变弱"。
明白这个道理，但一般答题时都靠感觉。还是记住一点理论，碰到犹豫选项时才能更好地判断。
