Which detail best supports the central idea that industries are using computers in innovative ways? We are in the midst of revolutionary changes that are extending the mental energy and ability of people. While in the past we used computers strictly for computing and information storage, we are now using them to solve problems. The study of these methods is called artificial intelligence. As the broad potential for artificial intelligence is discovered, more and more businesses are investing in artificial intelligence research. The medical field uses this technology in programs for diagnosing various diseases. The doctor tells the computer the patient's symptoms, and the computer continues to ask about symptoms until it determines a diagnosis. Similar programs are also being used to trouble-shoot problems in the operations of computers. As the knowledge base of a program grows, it becomes more and more sophisticated in the problems it can solve. We typically use computers to do much of the tedious work we used to do ourselves. Computers are increasingly being used as tools to enhance our creative and innovative abilities as well.
