High-technology medicine is driving up the nation’s health care costs. Recent advances in cataract surgery illustrate why this is occurring. Cataracts are a major cause of blindness, especially in elderly people. Ten years ago, cataract surgery was painful and not always effective. Thanks to the new technology used in cataract surgery, the operation now restores vision dramatically and is less expensive. These two factors have caused the number of cataract operations performed to increase greatly, which has, in turn, driven up the total amount spent on cataract surgery.
Which one of the following can be inferred from the passage

A．Ten years ago, few people had successful cataract surgery.

B．In the long run, the advantages of advanced medical technology are likely to be outweighed by the disadvantages.

C．The total amount spent on cataract surgery has increased because the increased number of people electing to have the surgery more than offsets the decrease in cost per operation.

D．Huge increases in the nation’s health care costs are due primarily to increased demand for surgery for older people.

E．(E) Ten years ago, cataract surgery was affordable for more people than it was last year.
