OG11-100请教

One way to judge the performance of a company is to compare it with other companies,This technique,commonly called"benchmarking" permits the manager of a company to discover better industrial practices and can provide a justification for the adoption of good practices.

Any of following,if true ,is a valid reason for benchmarking the performance of a company against companies with which it is not in competition rather than against competitiors EXCEPT:

A.Comparisons with competitors are most likely to focus on practises that the manager making the comparison already employs.

B. Getting "inside" imformation about the unique practices of competitors is particlulary difficult.

C.Since companies that compete wiht each otherr are likely to have comparable levels of efficiency ,only benchmarking against noncompetitors is likely to real practices that would aid in beating competition

D.Managers are generally more receptive to new ideas that they find outside their own industry.

E, Much of the sucess of good companies is due to their adoption of practices that take advantage of the special circumstances of their products of market.

不太明白这道题目的逻辑内涵？请各位侠客帮忙赐教一下啊

就是问为什么benchmarking应该在非竞争对手间进行，而不应该在竞争对手间进行。注意except，就是答案应该是相反的。

我认为应该选e，其他几个答案都说明了在竞争对手间进行benchmarking的问题。

这样一说就明白多了，感谢！

应该是自己先前没读懂这道题的提问内容。

俺也选择E。

E是正确答案么？

正确答案的确是E

答案E

前四项可以排除，但对E还是不大理解

E)Much of the success of good companies is due to their adoption of practice that take advantage of the special circumstances of their product or markets.－－从哪里可以看出是和competitor  benchmarking 啊，是说"of their product or market" 即意味着benchmarrking competitor相关吗？

我也有同样的疑问。

另外选项A 是什么意思？哪位NN能翻译一下？我不是很理解。谢谢！鞠躬！

A.Comparisons with competitors are most likely to focus on practises that the manager making the comparison already employs.

我觉得E选项中的companies应该改为competitors才对吧？
