单选题Among the most enduring of all horrors is the prospect of a slow, painful death. Those who witness the protracted terminal illness of a friend or relative often view the eventual death more as a relief than a tragedy. But to make life-or-death decisions on behalf of a dying person unable to communicate his or her wishes is to enter a moral and legal minefield. Could a doctor be sued for withholding treatment and allowing someone to dieor for not allowing him or her to die? Could it ever be lawful to withhold food and water? Legal moves are afoot which may settle these questions. Recently, a group on voluntary euthanasia proposed legislation to make documents known as "Advance Directives", or Living Wills, legally binding. An Advance Directive sets out the kind of medical treatment a person wishes to receive, or not receive, should he or she ever be in a condition that prevents them expressing those wishes. Such documents, much in vogue in the US and some Commonwealth countries, are becoming increasingly popular in Britain. A clear distinction must be drawn between actions requested by an Advance Directive, and active euthanasia, or "mercy killing". A doctor who took a positive step such as giving a lethal injection-to help a patient die would, as the law stands, be guilty of murder or aiding and abetting suicide, depending on the circumstances. An Advance Directive, however, requests only passive euthanasia: the withholding of medical treatment aimed solely at sustaining the life of a patient who is terminally ill or a vegetable. The definition of medical treatment, in such circumstances, can include food and water. The enforceability of the Advance Directive stems from the notion, long accepted in English law, that a person who is both old enough to make an informed decision and compos mentis, is entitled to refuse any medical treatment offered by a doctor, even if that refusal leads to the person's death. A doctor who forces treatment on a patient against his or her wishes is, therefore, guilty of an assault. Case law exists in the US and several Commonwealth countries that extends this right of autonomy over one's life to patients who write an Advance Directive refusing treatment and subsequently lose their previously made instructions any differently.

单选题Companies have embarked on what looks like the beginnings of a re-run of the mergers and acquisitions (M&A) wave that defined the second bubbly half of the 1990s. That period, readers might recall, was characterized by a collective splurge that saw the creation of some of the most indebted companies in history, many of which later went bankrupt or were themselves broken up. Wild bidding for telecoms, internet and media assets, not to mention the madness that was Daimler's $40 billion motoring takeover in 1998-1999 of Chrysler or the Time-Warner/AOL mega-merger in 2000, helped to give mergers a thoroughly bad name. A consensus emerged that M&A was a great way for investment banks to reap rich fees, and a sure way for ambitious managers to betray investors by trashing the value of their shares. Now M&A is back. Its return is a global phenomenon, but it is perhaps most striking in Europe, where so far this year there has been a stream of deals worth more than $600 billion in total, around 40% higher than in the same period of 2004. The latest effort came this week when France's Saint-Gobain, a building-materials firm, unveiled the details of its￡3.6 billion ($6.5 billion) hostile bid for BPB, a British rival. In the first half of the year, cross-border activity was up threefold over the same period last year. Even France Telecom, which was left almost bankrupt at the end of the last merger wave, recently bought Amena , a Spanish mobile operator. Shareholder's approval of all these deals raises an interesting question for companies everywhere, are investors right to think that these mergers are more likely to succeed than earlier ones? There are two answers. The first is that past mergers may have been judged too harshly. The second is that the present rash of European deals does look more rational, but-and the caveat is crucial-only so far. The pattern may not hold. M&A 's poor reputation stems not only from the string of spectacular failures in the 1990s, but also from studies that showed value destruction for acquiring shareholders in 80% of deals. But more recent studies by economists have introduced a note of caution. Investors should look at the number of deals that succeed or fail (typically measured by the impact on the share price), rather than (as you might think) weighing them by size. For example, no one doubts that the Daimler-Chrysler merger destroyed value. The combined market value of the two firms is still below that of Daimler alone before the deal. This single deal accounted for half of all German M&A activity by value in 1998 and 1999, and probably dominated people's thinking about mergers to the same degree. Throw in a few other such monsters and it is no wonder that broad studies have tended to find that mergers are a bad idea. The true picture is more complicated.

单选题The discovery of life beyond Earth would transform not only our science but also our religions, our belief systems and our entire world-view. For in a sense, the search for extraterrestrial life is really a search for ourselves--who we are and what our place is in the grand sweep of the cosmos. Contrary to popular belief, speculation that we are not alone in the universe is as old as philosophy itself. The essential steps in the reasoning were based on the atomic theory of the ancient Greek philosopher Democritus. Yet philosophy is one thing, filling in the physical details is another. Although astronomers increasingly suspect that biofriendly planets may be abundant in the universe, the chemical steps leading to life remain largely mysterious. Traditionally, biologists believed that life is a freak--the result of a zillion-to-one accidental concatenation of molecules. It follows that the likelihood of its happening again elsewhere in the cosmos is infinitesimal. This viewpoint derives from the second law of thermodynamics, which predicts that the universe is dying--slowly and inexorably degenerating toward a state of total chaos. And similar reasoning applies to evolution. According to the orthodox view, Darwinian selection is utterly blind. Any impression that the transition from microbes to man represents progress is pure chauvinism of our part. The path of evolution is merely a random walk through the realm of possibilities. If this is right, there can be no directionality, no innate drive forward; in particular, no push toward consciousness and intelligence. Should Earth be struck by an asteroid, destroying all higher life-forms, intelligent beings would almost certainly not arise next time around. There is, however, a contrary view--one that is gaining strength and directly challenges orthodox biology. It is that complexity can emerge spontaneously through a process of self- organization. If matter and energy have an inbuilt tendency to amplify and channel organized complexity, the odds against the formation of life and the subsequent evolution of intelligence could be drastically shortened. Historically, Bertrand Russell argued that a universe under a death sentence from the second law of thermodynamics rendered human life ultimately futile. All our achievements, all our struggles, "all the noonday brightness of human genius," as he put it, would, in the final analysis, count for nothing if the very cosmos itself is doomed. But what if, in spite of the second law of thermodynamics, there can be systematic progress alongside decay? For those who hope for a deeper meaning or purpose beneath physical existence, the presence of extraterrestrial life-forms would provide a spectacular boost, implying that we live in a universe that is in some sense getting better and better rather than worse and worse.
