Text 2 Across the developed world, health-care spending is rising and will continue to in crease as populations age. As each country feels the financial strain, it is tempting to imagine that there must be a better way of funding medical care elsewhere. In Britain, for example, Bernard Ribeiro, the new president of the Royal College of Surgeons, has called for the National Health Service (NHS) to be financed from social-insurance contributions, as in Germany and France, rather than from general taxation. He worries that a tax-financed system will not deliver enough resources to meet the demand for health-care spending in the longer run. There are indeed good reasons for concern about the way the NHS is financed, for it has allowed the government to pump in too much money too fast. But there is no ideal sys tem for paying for health care. The European social-insurance model is in even more trouble than Britain’s tax-based model. By loading the burden on to employers a

Across the United States, scientists are mounting what may become the most innovative agricultural research drive since the 1920s,when hybrid corn was developed. Surprisingly, the new genetic revolution is not taking place in America’s fields. Instead, it is occurring in biology laboratories, for it involves the deliberate manipulation in test tubes of the genes of crop plants. This genetic engineering may prove the biggest boon to agriculture since plant breeding began.
The new concepts grew out of the bioengineering of bacteria for the production of such things as human hormones and vaccines for viral diseases. Plant cells, however, are far more complex than bacteria, and it will probably take many years for today’s encouraging laboratory results to have a major impact on the farm. In fact the payoff may not come until the next century.
But although biotechnologists are still in the earliest phases of this new field of science, they are alread
A. experiments on plants in the fields
B. developing strains of hybrid corn
C. breeding plants in test tubes
D. rearranging plant genes in laboratories
