Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Over the years, Americans have become used to salt.Most people have no idea how much salt they consume-on average, about 9 to 12 gram per person per day, according to the American Heart Association.That's twice the amount recommended by the government. A new study last week showed eating even a little less salt could greatly help the heart.The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease. Researchers also found that the benefits would be greatest for African Americans and women.As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr.Kirsten Bibbins-Domingo, an epidemiologist at the University of California, San Francisco.Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%.A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%. They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. However, other scientists say such a campaign is an experiment with the health of millions of people. Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure.But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. "Salt has other biological effects. Calling for reductions in the national diet could have good effects, as well as harmful results. There is not enough evidence either way,"said Michael Alderman.

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: You may have heard the popular saying, "there are always more fish in the sea". But as many new studies show, fish populations are changing, and not necessarily for the better. Consider the case of big, predatory fish. These giants, like sharks and cod , eat other smaller fish. Big fish are an important part of the marine ecosystem because they keep down the numbers of smaller fish. Without fish that eat other fish, populations of smaller swimmers would increase, eating more plants, and leaving less vegetation for other creatures, including future fish. As fierce as predators can be, they're no match for fishing technology. Many people love to catch predatory fish like sharks, cod and tuna, and new studies suggest that over-fishing is threatening these creatures near the top of the marine food chain. In one study, Villy Christensen and his colleagues looked at 200 past studies of marine life to learn how fish populations have changed over time. Christensen reported that between 1910 and 1970, the numbers of big predators decreased slowly, and that in 1970 their populations really started to drop. Around that time, fishing ships began using new tools that led to more fish being caught. The numbers have been falling quickly ever since. Reg Watson looked at the problem from the perspective of the fishermen. In the middle of the 20thcentury, Watson reported, fishing boats didn't go far from home, and most fish were caught near the shore. That was no longer true by the 1980s. By then, fishing had moved farther from shore, into the open oceans, and was helped by the development of new technologies. But since the 1990s, something has changed. Despite new technologies and more efforts, fishing operations have not continued to develop. Scientists study historical data to understand the present, and this research is needed to forecast the future of fish and fishing. And the forecast doesn't look good: large predator fish are becoming harder to find, and soon may disappear. Options: A It may soon be difficult to find large predator fish. B It will cost much more in the future to catch big fish. C Smaller fish still give the fishing industry a bright future. D It is tough for researchers to forecast the future of fish. Answer: A It may soon be difficult to find large predator fish. Question:
