请教OG10 150

150.  United States hospitals have traditionally relied primarily on revenues from paying patients to offset losses from unreimbursed care．Almost all paying patients now rely on governmental or private health insurance to pay hospital bill. Recently, insurers have been strictly limiting what they pay hospitals for the care of insured patients to amounts at or below actual costs．

Which of the following conclusions is best supported by the information above?

(A)  Although the advance of technology has made expensive medical procedures available to the wealthy, such procedures are out of the reach of low-income patients．

(B)  If hospitals do not find ways of raising additional Income for unreimbursed care，they must either deny some of that care or suffer losses；if they give it．

(C)  Some patients have incomes too，high for eligibility for governmental health insurance but are unable to afford private insurance for hospital care．
            

(D)  If the hospitals reduce their costs in providing care，insurance companies will maintain the current level of reimbursement，
            thereby providing more funds for unreimbursed care．

如果这样改的话, 就承认"医院reduce their cost"和"保险公司maintain the current level of reimbursement"可同时存在! 

这样就与原文中的 insurance companies will only reimburse " amounts at or below actual costs" 相矛盾!

所以即使这样改的话, D也不可能成为正确答案! 请NN指正.
