Answers: B and C - Age integration can refer to people in any age group and promotes the opportunity for all to work, learn, or play as they wish, regardless of age. Age integration theory draws on a premise of age stratification theory with the idea that society is based on age. This can create age-segregated institutions and acts as a barrier to entrance, exit, or participation. The good news is that we are becoming a more integrated society in many institutions and ways; think of the many universities, colleges, and community learning centers that have young and older students.
