问题     Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
    The result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings.
    Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
    The study is in the New England Journal of Medicine. Kirsten at the University of California, was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
    Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
    The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen-seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
    New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants.
    Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute shows how that idea can influence what parents order for their children.
    Ninety-nine parents of three to six year olds took part. Half had McDonald’s menus clearly showing how many calories were in each food. The other half got menus without the calorie information.
Researchers from the following universities are involved in the study except______.
选项 A、Columbia University
B、Stanford University
C、New England University
D、California University
答案C
解析 第四段提到参与研究的大学有Columbia University，Stafford University．CaliforniaUniversity，故排除C。
