22. GWD-18-Q38

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 C

看原文：找出结论和推出该结论的前提。特别注意结论的特殊性和具体性。

找答案：用结论的具体性去区分有关无关，并结合TEST。对于特殊类，先预测出答案，用此预测去找答案

TEST：问自己，是否该答案使作者再考虑他的观点或迫使作者做出反应或原文该前提能证明该结论吗。

几种特殊类型：

原文前提和结论关系不密切：正确选项直接WEAKEN结论

因果型结论：即原文给出两件事，然后得出结论说是一件事（因）导致另一件事（果）。WEAKEN该结论的方法包括：A。是其他原因或可能导致该结果。B。割断因果：或有因无果或有果无因。C。因果颠倒了。D显示因果关系的资料不准确。

条件型结论：结论带条件（即为充分必要）。WEAKEN的方法显示充分条件成立，必要条件可以不成立。或举反例，或提供有关信息。

原文是类比：WEAKEN方式为两者本质不同

调查：有效性受怀疑（被调查的没代表性等）

1. 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.原文说，没出正式计划的只用了那些出正式计划的公司的一半的时间就获得了投资。结论说，这表明正式计划对获得投资没有帮助。哪个能够削弱结论呢？（一个是从结论上直接削弱，一个是削弱例子中引用的证据）C说，看起来好象是不出计划就获得了投资，但是，那些不出计划而获得投资的是因为他们和那些投资公司的一直以来的关系才获得投资的，并不是他们出没出计划。该题削弱证据
