That the as are being overfished has been known for years. What rearchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
We can infer from Dr. Myers and Dr. Worm’s paper that ________.
[A] the stock of large predators in some old fisheries has reduced by 90%
[B] there are only half as many fisheries as there were 15 years ago
[C] the catch sizes in new fisheries are only 20% of the original amount
[D] the number of larger predators dropped faster in new fisheries than in the old

How things have changed! In 1995 the United States can look back on five years of solid growth while Japan has been struggling. Few Americans attribute this solely to such obvious caus as a devalued dollar or the turning of the business cycle. Self doubt has yielded to blind pride. "American industry has changed its structure, has gone on a diet, has learnt to be more quick witted," according to Richard Cavanagh, executive dean of Harvard's Kennedy School of Government. "It makes me proud to be an American just to e how our business are improving their productivity," says Stephen Moore of the Cato Institute, a think tank in Washington, DC. And William Sahlman of the Harvard Busin
ess School believes that people will look back on this period as "a golden age of business management in the United States."
The author ems to believe the revival of the U.S. economy in the 1990s can be attributed to
the ________.
[A] turning of the business cycle
[B] restructuring of industry
[C] improved business management
[D] success in education

In an odd way, however, it is the educated who have claimed to have given up on ambitio
n as an ideal. What is odd is that they have perhaps most benefited from ambition. There is a heavy note of hypocrisy in this, a ca of closing the barn door after the hors have escaped —with the educated themlves riding on them.
The last ntence of the first paragraph most probably implies that it is ________.
[A] customary of the educated to discard ambition in words
[B] too late to check ambition once it has been let out
[C] dishonest to deny ambition after the fulfillment of the goal
