[单项选择]In the last week of August, 70 two-ton bulls climbed to the top of a cliff above Maggie Beach, a remote and forbidding area in southwestern Alaska. One by one, the huge and ungainly mammals waddled over the edge and fell 100 feet onto the rocks below. It was the third consecutive year that walruses plunged to their death on this beach — and scientists still can’t explain why.
For as long as humans can remember, every summer walrus bulls "haulout" along the beaches of Bristol Bay to sun and feed themselves in anticipation of the long winter ahead. Until the fall of 1994 the walruses were content to lounge along the sandy shore. Then one day, says Togiak Reserve manager Aaron Archibeque, a fierce storm struck the cape, and some of the animals retreated up a bluff in search of shelter, or so scientists thought. Perhaps disoriented or unsteady on rain-slickened grass, 42 of the bulls fell over the edge of the cliff. During another storm in October 1995, 17 more died.
But this

[单项选择]Last week oil prices finally stopped rising. They now hover around $43 a barrel, a 20-year high. The average American family will spend about $2,700 on gasoline this year (driving 22,000 miles). That’s twice as much as it spent on gas two years ago. These prices are having a predictable consequence. The consumer price index has risen by 4.9 percent to date, versus 1.9 percent last year. And last week President Bush’s economic adviser, Gregory Mankiw, acknowledged that a $10 rise in the price of oil probably translates into a half-percentage-point drag on economic growth. For countries like Japan, China and India, the effect is even greater. How did this happen And can Washington—or anybody—to much about it
