单选题The establishment of Earth Day began with an idea proposed in October 1969 by John McConnell, a San Francisco resident. McConnell approached the San Francisco Board of Supervisors with a resolution to devote one day a year to public awareness dedicated to nature and the weak ecosystem that makes up it. The day's events would emphasize the urgency of all inhabitants of the planet to take responsibility for building a healthy and ecologically sustainable planet for the present and long into the future. The board was impressed with McConnell's idea and declared Earth Day an annual celebration to be held on March 21, the date of the vernal equinox. McConnell stated "This is the moment when night and day are equal throughout the earth — reminding us of Earth's beautiful systems of balance which humanity has partially upset and must restore." Earth Day was established as a national day of celebration in the United States in 1970 and was embraced by the United Nations in 1971 when it declared an Earth Day ceremony to be held each year on the day of the March Equinox. When the first Earth Day was celebrated in the United States on April 22, 1970, twenty million participants nationwide took part in teach-ins, street demonstrations, and workshops in 2,000 communities and 12, 000 college and high school campuses. The major public concern at that time was industrial pollution and its effect on the air we breathe, the water we drink, and the health of the planet we live in. Those celebrations led to powerful public outcries for legislation mandating ecologically sound environmental policies and rigid controls on industrial pollution. Over the years, the issues of concern have expanded greatly into all aspects of air, water, soil, and noise pollution. Whether it comes from vehicles, factories, agriculture, housing, or private property, public concern and activism continue with citizens from around the world involved in efforts to achieve a sustainable and enduring ecosystem. Earth Day activities are supported and sponsored by a large network of organizations, government agencies, businesses, universities, and institutions. They work diligently each year to make Earth day events meaningful and relevant to the inhabitants of Planet Earth. The regular observance of this holiday fixes environmental values into the national consciousness and provides an opportunity to introduce environmental issues into schools, media and public events. It should be noted that Earth Day activities have been instrumental in bringing about many of the significant environmental changes that have taken place in the last three decades.

单选题The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect, "a centuries-old moral principle holding that an action having two effects—a good one that is intended and a harmful one that is foreseen—is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally iii patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death." George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide." On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the under treatment of pain and the aggressive use of "ineffectual an forced medical procedures that may prolong and even dishonor the period of dying" as the twi problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a medicare billing code for hospital-base care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiative translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering", to the extent that it constitutes "systematic patient abuse". He says medical licensing boards "must make it clear.., that painful deaths are presumptively ones that are incompetently managed and should result in license suspension".

单选题The popular idea that classical music can improve your maths is falling from favor. New experiments have failed to support the widely publicized finding that Mozart's music promotes mathematical thinking. Researchers reported six years ago that listening to Mozart brings about short-term improvements in spatial-temporal reasoning, the type of thinking used in maths. Gordon Shaw of the University of California at Irvine and Frances Rauscher of the University of Wisconsin in Oshkosh had asked students to perform spatial tasks such as imagining how a piece of paper would look if it were folded and cut in a certain pattern. Some of the students then listened to a Mozart sonata and took the test again. The performance of the Mozart group improved. Shaw found. He reasoned that listening to Mozart increases the number of connections between neurons. But Kenneth Steele of Appalachian State University in North Carolina learnt that other studies failed to find this effect. He decided to repeat one of Shaw's experiments to see for himself. Steele divided 125 students into three groups and tested their abilities to work out how paper would look if cut and folded. One group listened to Mozart another listened to a piece by Philip Glass and the third did not listen to anything. Then the students took the test again. No group showed any statistically significant improvement in their abilities. Steele concludes that the Mozart effect doesn't exist. "It's about as unproven and as unsupported as you can get," he says. Shaw however defends his study. One reason he gives is that people who perform poorly in the initial test get the greatest boost from Mozart but Steele didn't separate his students into groups based on ability. "We're still at the stage where it needs to be examined," Shaw says. "I suspect that the more we understand the neurobiology, the more we'll be able to design tests that give a robust effect. "
