1根据以下资料，回答题：
        Federal efforts to aid minority businesses began in the 1960's when the Small Business Administration (SBA) began making federally guaranteed loans and government-sponsored management and technical assistance available to minority business enterprises． While this program enabled many minority entrepreneurs to form new businesses, the results were disappointing, since managerial inexperience, unfavorable locations, and capital shortages led to high failure rates．Even 15 years after-the program was implemented, minority business receipts were not quite two percent of the national economy's total receipts．
        Recently federal polieymakers have adopted an approach intended to accelerate the development of the minority business sector by moving away from directly aiding small minority enterprises and toward supporting large, growth-oriented minority firms through intermediary companies．In this approach, large corporations participate in the development of successful and stable minority businesses by making use of governmentsponsored venture capital．The capital is used by a participating company to establish a Minority Enterprise Small Businesses that have potential to become future suppliers of customers of the sponsoring company．
        MESBICs (Minority Enterprise Small Businesses Intermediary Companies) are the result of the belief that providing established firms with easier access to relevant management techniques and more job,specific experience, as well as substantial amounts of capital, gives those firms a greater opportunity to develop sound business foundations than does simply making general management experience and small amounts of capital available．Further, since potential markets for the minority businesses already exist through the sponsoring companies, the minority businesses face considerably less risk in terms of location and market fluctuation．
        Following early financial and operating problems, sponsoring c0rporations began to capitalize MESBICs far above the legal minimum of $500,000 in order to generate sufficient income and to sustain the quality of management needed．MESBICs are now emerging as increasingly important financing sources for minority enterprises．
        Ironically, MESBIC staffs, which usually consist of Hispanic and Black professionals, tend to approach investments in minority firms more pragmatically than do many MESBIC directors, who are usually senior managers from sponsoring corporations．The latter often still think mainly in terms of the "social responsibility approach" and thus seem to prefer deals that are riskier and less attractive than normal investment criteria would warrant．Such differences in viewpoint have produced uneasiness among many minority staff members, who feel that minority entrepreneurs and businesses should be judged by established business considerations．These staff members believe their point of view is closer to the original philosophy of MESBICs and they are concerned that,unless a more prudent course is followed, MESBIC directors may revert to policies likely to re-create the disappointing results of the Original SBA approach．

The SBA program failed to get an expected result in that __________

A．the program had difficulty in winning financial support from the government
B．the program didn't create a stable and sound investment environment
C．minority people are not willing to start their own business
D．minority entrepreneurs lack experience, good locations and enough capital
