15.   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）

(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.

E对，A为什么不对呢？文中说风险投资的企业更容易成功，推出风险投资比其他因素对企业的成功更重要，A说风险投资家在选择投资时更负责任，也就是所企业本身就会成功，风险投资家才选择投资它，而不是因为风险投资家投资了该企业，才导致该企业成功，正好因果颠倒，也是削弱啊。

you misunderstand A. A - VC is more responsive to changes in financial needs, means vc can meet financial requirements from start-up company. A support topic conclusion that financial sourcing play importmant role in the success of start-up company.
