[单选题]Text 2 As lawmakers fight over what conditions insurance companies should be required to cover,other areas of health-care reform remain painfully neglected.One major example:How much should insurance companies pay for what they cover?Consumers rarely care about health-care prices beyond what they personally pay for deductibles,co-payments and prescription drugs.But insurance payments are crucial to understanding why health-care prices have gotten so out of control in the United States.A new study published in JAMA Internal Medicine makes this abundantly clear:Hospital emergency departments across the country are prone to excessively overcharge patients with private insurance,the study found,demanding that patients pay-on average-more than four times what Medicare pays for typical emergency procedures.This is not the heritage of sound medicine.This is the outcome of an extremely complicated and disjointed health-care system-and it's not necessarily the result of greedy hospitals trying to milk large profits out of vulnerable populations.Instead,it's the result of messy provider networks-rife with discounts and confusing contracts,designed by insurance companies and providers to attract customers.There are policy solutions to correct this system.Maryland,for example,has long operated under an"all-payer system"in which everyone pays the same rate for the same treatment-set by an independent state agency.Under this system,Medicare pays higher rates for care than in other states,but in the long run,it saves money-to the tune of$319 million-because the payment system incentivizes hospitals to reduce the number of people they admit.In other words,it encourages payment for quality of care,not quantity.Health-care providers have an incentive to work more closely with nursing facilities to deliver preventive care.Physicians also work more closely with patients to reduce preventable complications and hospital readmissions,which have dropped in Maryland faster than the national average in recent years.This innovative approach to solving price disparities in health-care costs is refreshing,although what works in Maryland might not work everywhere else.But other states have also passed laws to reduce price variation in health care,particularly for uninsured and low-income patients who would be most harmed by surprise medical bills.Unfortunately,reform efforts led by Republicans in Congress will likely worry the health-care industry enough to threaten state-led initiatives.Uncertainty-especially in terms of what our insurance markets will look like a year from now-makes it difficult,if not impossible,for states to experiment with different policies.That's a shame,because that's where the exciting and innovative reforms are happening.
The wide variation in health-care prices is mainly caused by_____
A.the vulnerable populations
B.the greedy hospitals
C.differences in treatment preferences
D.the disorganized provider networks

[单项选择]Minutes of the meeting held in Malupit Community School on Wednesday, 14th March, at 8:00 p. m, Mr. I. Pomat, a Malupit shop owner, called the meeting to find out the views of the community on local government plans to close the Malupit Community School at the end of the present school year.
Mr. Pomat acted as chairman of the meeting. He introduced Mr. L. Karazin, the Planning Office of the Raval Education Department. Mr. Karazin pointed out that there were now only fifty-three children at Malupit Community School. This was considered to be too high a number for the forming of two classes and the employment of two teachers. Mrs. Luvako, who had taught at the school for the past twenty-two years, would be retiring from the teaching service in July. The Planning Office wished to take this opportunity to close the school, because it is expensive to run, and to move the children to two bigger schools in Raval, six miles away.
