单选题The Supreme Court will hear arguments about the use of public money for the private schooling of children with special needs. It's interesting to note what's not at issue: namely, that when a public school system is unable to provide an appropriate education, it is obligated to pay the costs of private school. Too bad poor children don't have that unshakable right; if they did, there would be no controversy about the District program that gives vouchers to low-income children to attend private schools. The case to be heard by the court hinges on whether parents have to enroll a child with special needs in public school before the child can attend private school at public expense. Special-education advocates say students shouldn't have to waste time before being placed in a setting that best suits their needs, while school boards worry about a ruling that could amount to an unfettered fight to private schooling at public expense. What strikes us about the emotionally charged debate is the acceptance by both sides that sometimes it is appropriate to use public money to pay for a child to go to a private school. So, why all the arguments about the approximately$14 million for a federally funded program that lets 1,700 D. C. students attend private schools instead of failing public schools? To hear critics of the D. C. Opportunity Scholarship Program tell it, the use of public money for private schooling is as unprecedented as it is undesirable. In addition to the billions of dollars spent annually on private school tuitions for students with disabilities, private schools get public money for books, technology and teacher training. As long as the money is seen as benefiting the child, it is considered a proper, even desirable, use of public dollars. Don't get us wrong. We're not arguing for the unilateral right of parents to enroll their sons and daughters in any school they wish with the taxpayers picking up the bill. Abuse of special-education policies has contributed to increased costs that threaten to take needed money from general public education funds. Safeguards are needed. Public schools should be pressed to do a better job for students with disabilities and students without. But there are schools in Washington where statistics show that failure is almost guaranteed. If a school system can't educate a child—whether because of acute special needs or its own historical failings—why should that child not have options for a " free appropriate public education " ?

单选题How long you live has a lot to do with your environment and lifestyle, but exceptional longevity may have even more to do with your genes. For the first time, researchers have identified a genetic recipe that accurately predicts who may live to 100 and beyond. Scientists led by Dr. Thomas Perls at the Boston University School of Medicine conducted a genetic analysis of more than 1,000 centenarians and their matched controls and found 150 genetic variants--or bits of DNA--that differed between the two groups. These variants identified people who lived to a very old age (past 100) with 77% accuracy, researchers found. Further analysis identified 19 distinct genetic profiles associated with extremely long life; 90% of participants who lived to 100 possessed at least one of the signature genetic clusters. Each profile appeared to confer a different tendency to develop common age-related chronic diseases, such as heart disease or brain disorder. "We realize this is a complex genetic puzzle," Perls said. "We're quite a ways away still in understanding how the integration of these genes--not just with themselves but with environmental factors--are playing a role in this longevity puzzle." Perls has studied many factors that contribute to longevity, and he is the first to acknowledge that living longer isn't likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% of their longevity can be ascribed to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and intellectually active throughout life. Still, it seems clear that those who live to an exceptionally ripe old age are benefiting from a special DNA boost. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years. His current genetic findings support that theory: the 19 most common genetic profiles that distinguished the exceptionally long-lived appear to be correlated with lower incidence of certain diseases. For example, some profiles were associated with lower rates of high blood pressure and diabetes, while another was linked to a reduced risk of brain disorder. Although most of us can't expect to become centenarians, Perls is hoping that his work will lead to better ways--perhaps through pharmaceutical interventions based on the genetic clues to longevity--to help more of us live like them.
