ａ　我还是能看明白　算个偷换概念　应该是ｐｒｏｄｕｃｔｉｖｉｔｙ　而不是　ｉｄｅａ　

但是ｅ　能不能　算是　因果倒置呢～　麻烦看一下

E应该是无关项。说的只是break会因frustration而更多，和productivity没关系。

  可是frustration 是因为 low production 阿

  仍然困惑中....

  求救！！

First, the conclusion of the argument is ">6 breaks per day=>low productivity".  Frustration may be an explanation for breaks and low productivity, it has nothing to do with the conclusion.  Second, to weaken the argument (ideas= productity), always attack the assumption to point there is a logical flaw in the argument.
