单选题In the United States the per capita costs of schooling have risen almost as fast as the cost of medical treatment. But increased treatment by both doctors and teachers has shown steadily declining results. Medical expenses concentrated on those above forty-five have doubled several times over a period of forty years with a resulting 3 percent increase in the life expectancy of men. The increase in educational expenditures has produced even stranger results; otherwise President Nixon could not have been moved this spring to promise that every child shall soon have the "Right to Read" before leaving school. In the United States it would take eighty billion dollars per year to provide what educators regard as equal treatment for all in grammar and high school. This is well over twice the $36 billion now being spent. Independent cost projections prepared at HEW and at the University of Florida indicate that by 1974 the comparable figures will be $107 billion as against the $45 billion now projected, and these figures wholly omit the enormous costs of what is called "higher education", for which demand is growing even faster. The United States, which spent nearly eighty billion dollars in 1969 for "defense", including its deployment in Vietnam, is obviously too poor to provide equal schooling. The President"s committee for the study of school finance should ask not how to support or how to trim such increasing costs, but how they can be avoided. Equal obligatory schooling must be recognized as at least economically unfeasible. In Latin America the amount of public money spent on each graduate student is between 350 and 1, 500 times the amount spent on the median citizen(that is, the citizen who holds the middle ground between the poorest and the richest). In the United States the discrepancy is smaller, but the discrimination is keener. The richest parents, some 10 percent, can afford private education for their children and help them to benefit from foundation grants. But in addition they obtain ten times the per capita amount of public funds if this is compared with the per capita expenditure made on the children of the 10 percent who are poorest. The principal reasons for this are that rich children stay longer in school, that a year in a university is disproportionately more expensive than a year in high school, and that most private universities depend—at least indirectly—on tax-derived finances. Obligatory schooling inevitably polarizes a society; it also grades the nations of the world according to an international caste system. Countries are rated like castes whose educational dignities determined by the average years of schooling of its citizens, a rating which is closely related to per capita gross national product, and much more painful.

单选题Editors of the world"s leading scientific journals announced Saturday they would delete details from published studies that might help terrorists make biological weapons. The editors, joined by several prominent scientists, said they would not censor scientific data or adopt a top-secret classification system similar to that used by the military and government intelligence agencies. But they said scientists working in the post-Sept. 11 world must face the dismaying paradox that many of their impressive breakthroughs can be used for sinister purposes. The new editing methods will be voluntary and will differ among the 32 publications and scientific associations that agreed to the effort. Those include the journals Science, Nature, Proceedings of the National Academies of Science, The New England Journal of Medicine and The Lancet. Most major advancements—from decoding the human genome to the cloning of Dolly the sheep—are revealed to the world through those journals. The new policy emerged from a Jan. 9 meeting at the National Academy of Sciences where researchers and journal editors reviewed potentially sensitive studies. They unveiled their agreement at the national meeting of the American Association for the Advancement of Science. Proponents acknowledged they are walking a " very fine line" in trying to protect the public without chilling research. Few, if any, of the thousands of research papers reviewed annually for publication would be rejected outright, they said. Papers would still contain sufficient details to allow other scientists to independently duplicate experiments—a vital step in validation discoveries. " We do live in different times now, " said Ronald Atlas, president of the American Society of Microbiology and a leader of the biosecurity review movement. "The information we possess has the potential for misuse. We will take the appropriate steps to protect the public. " Indeed, it has never been easier to tweak a microbe"s genes to create a deadlier, drug-resistant superbug for a germ bomb or hijack aerosol technology meant for convenient spray vaccines to make anthrax spores float through the air. Journal editors said they were establishing their own expert panels to review papers that contain alarming information, and would work with the authors to make specific changes and "tone them down. " Most journals rarely face such questions. Atlas said journals published by the microbiology association found only two research papers in that past year that raised eyebrows, and both were published after the authors agreed to changes. One of the excised details demonstrated how a microbe could be modified so it could kill 1 million people instead of 10, 000. "It was something that was best not told, " Atlas said. He declined to identify the microbe.
