题目如下：
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 credit 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 nonhierarchical 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

书中答案是B，我选的是D

我自己认为B是否命题架桥，并不能直接证明 nonhierarchical 的环境有助于“留人”

听听大家见解......

B

支持题目可以用非充分条件。钱不是万能的，没有钱是万万不能的。这里“nonhierarchical environment”就是钱。“necessary”还不够明显嘛？
