54. Most employees in the computer industry move from company to company, changing jobs several times in their careers. However, Summit Computers is known throughout the industry for retaining its employees. Summit credits its success in retaining employees to its informal, nonhierarchical work environment.
Which of the following, if true, most strongly supports Summit's explanation of its success in retaining employees?
(A)        Some people employed in the computer industry change jobs if they become bored with their current projects.
(B)        A hierarchical work environment hinders the cooperative exchange of ideas that computer industry employees consider necessary for their work.
(C)        Many of Summit's senior employees had previously worked at only one other computer company.
(D)        In a non-hierarchical work environment, people avoid behavior that might threaten group harmony and thus avoid discussing with their colleagues any dissatisfaction they might have with their jobs.
(E)        The cost of living near Summit is relatively low compared to areas in which some other computer companies are located.

答案是B，为什么D不行？个人觉得D更好的表述了公司是一个non-hierarchical的环境，和这个环境造成员工不容易互相抱怨破坏和谐，表述了员工留下来的理由。而B只是表述了另一个理由，两个有什么根本的不同？OG的那个解释没法接受....谢谢给我讲讲！！！

仔细想了n遍有点想法了。OG的解释是说D是说这种环境对员工行为的影响。
是不是D没有表示出这种影响对员工留下来有什么积极影响？但个人觉得B中也没有明说这种好的影响。

D：是说在非等级的公司里人们避免谈及一些危及公司融洽和讨论对工作不满的言论。人们只是避免而已，问题依然存在，跳槽的人还是会跳槽，表面功夫的好坏不是留下员工的原因。因此，表面功夫不能解释员工为何能留在公司，除非他们都是两面刀。

谢谢
努力

不是最后一问也没关系，我看好你哟～
