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.无关
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.增强
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.
结论：所以，formal plan没有帮助secure the capital.
论据：因为，平均，没有formal plan的企业家使用了更少的时间来获得资金。
削弱：可能是他因导致这些企业家时间少，formal plan的作用无法从论据体现。
没有看懂解释，答案是选C 作者: uibeantares 时间: 2012-1-1 12:59
削弱前提的基本逻辑是（1）要么找到导致结果的其他原因，从而降低题干中前提导致结果的可能性；（2）直接否定前提。 这题的逻辑结构是：formal plan没用---->结论：没有formal plan的创业者找到了更多的资金 C答案给出了其他的原因：靠亲戚朋友给钱---->没有formal plan的找到更多钱 所以实际上是给出了其他导致没有formal plan也能找到钱的原因，削弱了formal plan没用的可能性，所以选C答案。作者: Richardyu 时间: 2012-1-2 08:33

個人直覺選C，因為D說他們都做更多research,感覺沒有論據。所以C比較符合...雖然解釋不出來為啥。 弱弱的問一句，GWD是什麼？作者: Richardyu 时间: 2012-1-3 01:08

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?
