154.
Start-up companies financed by venture capitalist have a much lower failure rate than companies financed by other means. Source of financing, therefore, must be a more important causative factor in the success of a start-up company than are such factors as the personal characteristics of the entrepreneur, the quality of strategic planning, or the management structure of the company.
Which of the following, if true, most seriously weakens the argument above?
(A) Venture capitalists tend to be more responsive than other sources of financing to changes in a start-up company’s financial needs.
(B) The strategic planning of a start-up company is a less important factor in the long-term success of the company than are the personal characteristics of the entrepreneur.
(C) More than half of all new companies fall within five years.
(D) The management structures of start-up companies are generally less formal than the management structures of ongoing businesses.
(E) Venture capitalists base their decisions to fund start-up companies on such factors as the characteristics of the entrepreneur and quality of strategic planning of the company.
并不是很清楚154题的逻辑关系：
前提venture capitalist --》lower failure rate，所以结论Source of financing更重要。
第一种理解：答案是E，Venture capitalists 是基于characteristics和quality，所以characteristics和quality比Venture capitalists 更重要，这是他因weaken吗？
OG的解释是
it is possible that companies with those combinations of factors that are most likely to lead to success are the very companies that venture capitalists select for financing. This weakens the argument that the financing itself must be more important for success than those factors. Thus, E is the best answer.
第二种理解：characteristics和quality--》lower failure rate（成功率高），直接weaken前提？
请问牛牛，是哪一种正确？ |
