--- Please take a look at the question itself:

Which one of the following, if also shown by the survey, would most seriously call into question the conclusion made by the author of the passage?

Now take a look at choice A:

A) The dissatisfied workers feel that their wages are too low and working conditions are unsatisfactory.

Since A is also part of the survey, it is hard to make the worker change their feeling without raising wages and improving conditions.

是A，题干的结论是having little control toward their assignment是workers dissatisfied的原因。A中给出了另一个原因。

B错。changing the belief of workers本身并没问题。satisfied 和 dissatisfied并不是对立的，增加其中一个不需要以减少另一个为前提。
