求一道AA 题思路

jj 题， 我马上要考乐，不过这题的思路还是很局限，请大家帮忙看看：
“Eight years ago, our firm’s profits were increasing with each new employee we added. We discovered that each employee had the skills and motivation to generate more revenue for the firm than his or her salary cost us. However, for the past two years, our profit margin has been falling, even though we have continued to add employees. Thus, our newer employees are not generating enough revenue to justify their salaries. We must not be hiring new employees with the same level of skills and motivation as those we used to attract. Clearly, then, failures in the human resources department account for our falling profits.”

我的个人意见：

3个点：1.针对new empliyees are not generationg enough revenue to justify their salaries，我觉得是insufficient，profit margin的falling不代表profit falling；2.针对must not hire new employees，我觉得是faulse causality,argument hypothesize that hiring employee could rise the profit,列出他因；3.针对最后一句话，gratuitous assumption，HR department 无需为此负责，可归则于其他部门。

以上纯为个人意见，仅供参考。

1、边际效益降低和新员工的因果关系（列举它因）
2、新老员工对比，8年前的老员工和新晋员工可比性质疑
3、HR负责招聘的其中一块，决策权往往不在他们，责任难定

呵呵，再补充一些：
因果联系出错：
1。
for the past two years, our profit margin has been falling没有dress falling的原因，
归咎于：
our newer employees are not generating enough revenue to justify their salaries。
没有足够的理由来dress profit falling的原因，来support作者的论述。
falling可能其他方面导致的，比如competition，或是crisis等等，再或是公司的marketing search不充足，还有product的quality so on.

2，简单的把falling归咎到HR的出错，HR的功能只是根据其他部门的需求，初步的筛选人才，最重的决定权不在他们
