3. The city's public transportation system should be removed from the jurisdiction of the municipal government, which finds it politically impossible either to raise fares or to institute cost-saving reductions in service. If public transportation were handled by a private firm, profits would be vigorously pursued, thereby eliminating the necessity for covering operating costs with government funds.    BThe statements above best support the conclusion that(A) the private firms that would handle public transportation would have experience in the transportation industry(B) political considerations would not prevent private firms from ensuring that revenues cover operating costs(C) private firms would receive government funding if it were needed to cover operating costs (D) the public would approve the cost-cutting actions taken by the private firm(E) the municipal government would not be resigned to accumulating merely enough income to cover costs

a说私人公司要有交通工业方面的经验，文中没提；c,私人公司会得到政府资助，根本没有；d，文中没提public反应；e,文章只是说交通业应由私人公司控制，没提政府是不是该accumulating merely enough income to cover costs，根本无关；只有b,说政府不会阻碍个人公司(文中说政府应该让private firm handle)，能conclude statement.
