A survey of entrepreneurs who started companies last year shows that while virtually all did substantial preparatory research and planning, only half used that work to produce a formal business plan.Since, on average, the entrepreneurs without formal plans secured the capital they needed in half the time of those with plans, these survey results indicate that, in general, formal plans did not help the entrepreneurs who produced them to secure the capital they needed.

Which of the following, if true, most seriously weakens the argument?

A.Companies started by entrepreneurs who had used formal business plans to attract investment were on the whole as profitable in their first year as were companies started by entrepreneurs who had not produced such plans.

B.In surveys of entrepreneurs who have attempted without success to raise sufficient capital, more than half of the respondents indicate that they have produced a formal business plan.

C.Among the entrepreneurs surveyed, those who did not produce formal business plans sought and received a much larger proportion of their capital from investors with whom they had a long-standing business relationship.

D.The entrepreneurs surveyed who did not produce a formal business plan spent nearly as much time doing preparatory research and planning as the entrepreneurs who produced plans.

E.The entrepreneurs who produced business plans generally reported later that the process of writing the plan had increased their confidence that their company would succeed.

答案选B？？？
为毛我觉得答案是C咧。。 B 不是等于支持了作者的结论了吗？？

C. Those who did not write business plans used their connection to attract funding instead of using the merits of their work.

Let's use an analogy. Among the students who entered a MBA program, half have GMAT scores and half have not. However, those without GMAT scores got accepted because they knew the director in charge of the admission. Would this information weaken the conclusion that GMAT is useless in the application process?

楼上，
Yes, that information will definitely weaken the conclusion that GMAT is useless in process.
所以说，你也觉得选C么？
我也觉得选C。。。lz答案确定么？

8确定呀，所以才困惑。答案是前些天某位牛牛总结出来的逻辑重点难题集里的呀。

我觉得应该是E，The entrepreneurs who produced business plans

generally reported later that the process of writing the plan had

increased their confidence that their company would succeed.

正好削弱，因为E人从准备计划中获得自信更容易取得成功，C说的是E人从别人

那里获得资金，和题目说的计划不能帮他们获得资金这不就是支持了吗？

C, an alternative explanation.
