Critical Reasoning

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 bills. 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 governmnetal health insurance but are unable to afford private insurance for hospital care.
(D) If the hospitals reduce ther costs in providing care, insurance companies will maintain the current level of reimbursement, thereby providing more funds for unreimbursed care.
(E) Even though philanthropic donations have traditionally provided some support for the the hospitals, such donations are at present declining.
