单选题 Which of the following is true of the squirrel bridge?

A． It was replaced by a longer one
B． It was built from wood and metal
C． it was rebuilt after years of use
D． It was designed by Bill Hutch

参考答案C

解析:【答案】C。解析：根据文章倒数第二段中的“In l983，after 20 years of use，Peters took down the worn—out bridge．Repairs were made and crosspieces were replaced．"可知，绳索用了20年后，Peters进行了修缮，并替换上了新的绳索。因此C为正确答案。文中没有涉及是否替换的绳索更长；第五段中提到绳索是铝制的；Bill Hutch是参与施工者，而非设计者，故均排除。

单选题根据以下材料，回答题
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.
All the following are related to the salt in diet except

A． Strokes
B． heart attacks
C． blood pressures
D． stomach diseases
