Passage Three
If it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school system, however, has no such choice, for the jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services.
In education, there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation

[单选题]Biologists estimate that as many as 2 million lesser prairie chickens---a kind of bird living on stretching grasslands—once lent red to the often gray landscape of the midwestern and southwestern United States.But just some 22,000 birds remain today,occupying about 16%of the species’historic range.The crash was a major reason the U.S Fish and Wildlife Service（USFWS）decided to formally list the bird as threatened.“The lesser prairie chicken is in a desperate situation,”said USFWS Director Daniel Ashe.Some environmentalists,however,were disappointed.They had pushed the agency to designate the bird as“endangered,”a status that gives federal officials greater regulatory power to crack down on threats.But Ashe and others argued that the“threatened”tag gave the federal government flexibility to try out new,potentially less confrontational conservations approaches.In particular,they called for forging closer collaborations with western state governments,which are often uneasy with federal action and with the private landowners who control an estimated 95%of the prairie chicken’s habitat.Under the plan,for example,the agency said it would not prosecute landowner or businesses that unintentionally kill,harm,or disturb the bird,as long as they had signed a range—wide management plan to restore prairie chicken habitat.Negotiated by USFWS and the states,the plan requires individuals and businesses that damage habitat as part of their operations to pay into a fund to replace every acre destroyed with 2 new acres of suitable habitat.The fund will also be used to compensate landowners who set aside habitat,USFWS also set an interim goal of restoring prairie chicken populations to an annual average of 67,000 birds over the next 10 years.And it gives the Western Association of Fish and Wildlife Agencies（WAFW
A）,a coalition of state agencies,the job of monitoring progress.Overall,the idea is to let“states”remain in the driver’s seat for managing the species，”Ashe said.Not everyone buys the win-win rhetoric Some Congress members are trying to block the plan,and at least a dozen industry groups,four states,and three environmental groups are challenging it in federal court Not surprisingly,doesn’t go far enough“The federal government is giving responsibility for managing the bird to the same industries that are pushing it to extinction,”says biologist Jay Lininger.
