单选题The news from America's housing market is getting no better. As sales declines and defaults and foreclosures climb, pessimists fear that over a million Americans could be driven out of their homes as adjustable-rate mortgages are reset. What should policymakers do? Congress is eager to do more: hence the calls to expand the role of Fannie Mae and Freddie Mac, the giant government-sponsored enterprises (GSES) that tower over America's mortgage market. Fannie's and Freddie's political allies want two things. The first is the raising of the $417,000 limit on the size of loans that the pair may handle. The second demand is the lifting of caps on the amount of mortgages they may buy and hold for themselves. Fannie and Freddie could then ride to the rescue of struggling borrowers, injecting liquidity into parts of the market that have seized up. Their arguments are winning support, and opposition from the Bush administration and the GSES' regulator is softening. Unfortunately, the ideas are likely to do more for Fannie and Freddie than for the mortgage market. Start with the $417,000 limit. Lifting this could help if Fannie and Freddie scoured the upper bracket for borrowers who were struggling but viable. But their history suggests that they would cherry-pick those who could get refinanced elsewhere. And the huge-mortgage market may be correcting itself anyway: spreads over GSE-backed loans, though still unusually high, are falling. It is also riskier. When they hold a mortgage, they take on not only credit risk but also interest-rate and prepayment risk. The loans they guarantee, in contrast, carry only credit risk. So as well as being just as effective, the guarantee business is also safer—and thus better for the taxpayer who unwittingly stands behind the GSES. Moreover, even if they grow no more, the mortgage giants pose a clear systemic threat. Their portfolios of retained mortgages and mortgage-backed securities add up to no less than $1.4 trillion. It is bad enough that this is concentrated in two institutions. No matter how much risk they take or how they manage it, they can borrow at rock-bottom interest rates. If they got into trouble, banks as well as taxpayers would be on the hook. Banks may hold as much GSE debt as they want. Many have amounts that exceed their regulatory capital. The giants were set up decades ago to help banks pool concentrated regional mortgage risk and to make housing more affordable. But as the market has grown deeper and more sophisticated, history has left them behind—hence their desire to get into any bit of the business that will turn a profit. The eventual aim should be to turn them into normal private-sector companies, by stripping them of the charters that give rise to the implicit government guarantees, and break them into smaller pieces.

单选题The topic of cloning has been a politically and ethically controversial one since its very beginning. While the moral and philosophical aspects of the issues are entirely up to the interpretation of the individual, the application of cloning technology can be studied objectively. Many in the scientific community advocate the use of cloning for the preservation and support of endangered species of animals, which aside from cloning, have no other practical hope for avoiding extinction. The goal of the use of cloning to avoid extinction is the reintroduction of new genes into the gene pool of species with few survivors, ensuring the maintenance and expansion of genetic diversity. Likely candidates for this technique are species known to have very few surviving members, such as the African Bongo Antelope, the Sumatran Tiger, and the Chinese Giant Panda. In the case of Giant Panda, some artificial techniques for creating offspring have already been performed, perhaps paving the way for cloning as the next step in the process. With the estimated population of only about 1000 Giant Pandas left in the world, the urgency of the situation has led to desperate measures. One panda was born through the technique of artificial insemination in the San Diego Zoo in the United States. "Hua Mei" was born in 1999 after her parents, Hsing-Hsing and Ling-Ling, had trouble conceiving naturally. The plan to increase the Giant Panda population through the use of cloning involves the use of a species related to the Giant Panda, the American Black Bear. Egg cells will be removed from female black bears and then fertilized with Panda cells such as those from Ling-Ling or Hsing-Hsing. The fertilized embryo will then re-implanted into the black bear, where it will grow and mature, until a new panda is delivered from the black bear host. Critics of cloning technology argue that the emphasis on cloning as a method by which to preserve species will draw funding away from other methods, such as habitat preservation and conservation. Proponents of cloning counter that many countries in which many endangered species exist are too poor to protect and maintain the species' habitats anyway, making cloning technology the only practical way to ensure that those species survive to future generations. The issue is still hotly debated, as both sides weigh the benefits that could be achieved against the risks and ethical concerns that constantly accompany any argument on the issue.
