17. Working shorter workweeks causes managers to feel less stress than does working longer workweeks. In addition, greater perceived control over one’s work life reduces stress levels. It can be concluded, therefore, that shorter workweeks cause managers to feel they have more control over their work life.

The argument made above uses which of the following questionable techniques?

(A) Associating two conditions as cause and effect on the basis of their being causally associated with the same phenomenon

(B) Taking for granted that two factors that have a certain effect individually produce that effect more strongly when both act together

(C) Assuming what it sets out to prove

(D) Using an irrelevant point in order to draw a conclusion（A）

(E) Basing a conclusion on preconceived views about the needs of managers

有点绞，

题意说，ｗｏｒｋｉｎｇ　ｓｈｏｒｔｅｒ＋ｃｏｎｔｒａｌ都可以减压。

结论却说ｓｈｏｒｔｅｒ－－＞ｇｒｅａｔｅｒ　ｃｏｎｔｒｏｌ明显错误。所以选Ａ，ｗｈｉｃｈ　ｄｉｓｃｒｉｂｓ　ｔｈｅ　ｍｉｓｔａｋｅ　ａｐｐｒｏｐｅｒｉａｔｅｌｙ．．．

ａｍ　ｉ　ｒｉｇｈｔ？

谢谢楼主！！可是我怎么不懂红色部分？？我推不出其中的因果关系…………………………

红字部分是题目中得出的结论，就是从it can be concluded开始的那句话，我说的“工作时间少可以减压，而我们又知道经理们做感知到的对工作的CONTROL大也可以减压，所以可以得出结论工作时间少就会让人觉得对工作的CONTROL大”这句话是对题目的翻译，也就是题意。

Please read the second setence " In addition, greater perceived control over one’s work life reduces stress levels."

This is why A is correct.
