【答案解析】[解析] 11-15 In Kansas City, Missouri, a computer helps firemen. The computer contains information about every one of the 350,000 street addresses in the city. When firemen answer a call, the computer gives them important information about the burning building. The computer can give the location of the building and its size, type, and contents. In fact, the computer system has many different ways of helping fire fighters with their problems. For example, it can give medical information about sick people living in a burning building. With this information, the firemen can take special care to find these sick persons and remove them quickly and safely from the burning building. The speed of the computer is amazing. Within two or three seconds after a call is received, the computer provides necessary information for the firemen. The information is then sent to them by radio from the computer center in City Hall. The Kansas City computer system also contains a medical record of each of the city's 900 firemen. This kind of information is especially useful when a fire fighter is injured. With this medical information, doctors at the hospital can treat the injured firemen more quickly and easily. Kansas City firemen themselves are thankful for the computer's help. The computer tells them about possible dangers ahead of them and helps them prepare for them. Many times the computer information helps to save lives and property. Sometimes the lives are those of firemen themselves ! 11. How is information sent to the firemen?
