Which is NOT the purpose of the adult students taking part in adult programs?

Millions of Americans take part in adult education programs. Some adults are completing high school, college or graduate school work. They attend classes designed especially for working people on weekends or at night. Other adults take classes by mail or on their computers. For example, the University of Arizona Extended University is one of many colleges now providing such courses.
     Other adults learn job skills like computer science or woodworking. Still other adult students learn to read or improve their English.
     Some adult students are not trying to finish their education or learn job skills. Instead, they want to explore new interests. They want to learn to speak a foreign language, play a musical instrument or take good pictures. They attend continuing education programs at a community college or public school. For example, Montgomery College in Rockville, Maryland, offers many classes. They teach adults how to build a house or how to write their memoirs.
     An agency in the Federal Department of Education supervises public adult education programs. Also, the government offers classes in many subjects for adults through the departments of Agriculture and Defense. So do private companies, labor unions and other organizations. These subjects include the arts, science and business.
     Adult education classes meet in schools, public libraries and business offices. They also meet in religious centers and shopping centers. Classes in nature sciences and sports often take place outside.
