"There is a senseless notion that children grow up and leave home when they are 18, and the truth is far from that," says sociologist Lary Bumpass of the University of Wisconsin. Today, unexpected numbers of young adults are living with their parents. "There is a major shift in the middle class," declares sociologist Allasn Schnaiberg of Northwestern University, whose son, 19, moved back in after an absence of eight months. Analysts cite a variety of reasons for this return to the nest. The marriage age is rising, a condition that makes home and its pleasantness particularly attractive to young people. A high divorce rate and a declining remarriage rate are sending economically pressed and emotionally hurt survivors back to parental shelters. For some, the expense of an away-from-home college education has become so excessively great that many students now attend local schools. Even after graduation, young people find their wings clipped by skyrocketing housing costs. Living at home, says Knighton, a school teacher, continues to give her security and moral support. His mother agreed, "It"s ridiculous for the kids to pay all that money for rent. It makes sense for kids to stay at home." But sharing the family home requires adjustments for all. There are the hassles over bathrooms, telephones and privacy. Some families, however, manage the delicate balancing act. But for others, it proves too difficult. Michelle Del Turco, 24, has been home three times—and left three times. "What I considered a social drink, my dad considered an alcohol problem," she explains. "He never liked anyone I dated, so I either had to hide away or meet them at friends" houses." Just how long should adult children live with their parents before moving on Most psychologists feel lengthy homecomings are a mistake. Children, struggling to establish separate identities, can end up with "a sense of inadequacy, defeat and failure." And aging parents, who should be enjoying, some financial and personal freedom, find themselves stuck with responsibilities. Many agree that brief visits, however, can work beneficially. Which of the following is not the reason for young adults returning to the nest______

A. Young adults find housing costs too high
B. Quite a number of young adults attend local schools
C. Young adults seek parental comfort and moral support
D. Young adults are psychologically and intellectually immature

The more women and minorities make their way into the ranks of management, the more they seem to want to talk about things formerly judged to be best left unsaid. The newcomers also tend to see office matters with a fresh eye, in the process sometimes coming up with critical analyses of the forces that shape everyone"s experience in the organization. Consider the novel view of "Harvey Coleman of Atlanta on the subject of getting ahead. Coleman is black. He spent 11 years with IBM, half of them working in management development, and now serves as a consultant to the likes of AT&T, Coca-Cola, and Merth. Coleman says that based on what he"s seen at big companies, he weighs the different elements that make for long-term career success as follows: performance counts a mere 10%, image, 30%, and exposure, a full 60%. Coleman concludes that excellent performance is so common these days that while doing your work well may win you pay increases, it won"t secure you the big promotion. He finds that advancement more often depends on how many people know you" and your work, and how high they are. Ridiculous beliefs Not to many people, especially many women and members of minority races who, like Coleman, feel the scales have dropped from their eyes. "Women and blacks in organizations work under false beliefs," says Kaleel Jamison, a New York-based management consultant who helps corporations deal with these issues. "They think that if you work hard, you"ll get ahead—that someone in authority will reach down and give you a promotion," she adds. "Most women and blacks are so frightened that people will think they"ve gotten ahead because of their sex or color that they play down their visibility." Her advice to those folks: learn the ways that white males have traditionally used to find their way into the spotlight. According to the passage, "things formerly judged to be best left unsaid" (Para. 1) probably refers to ______

A. criticisms that shape everyone"s experience
B. the opinions which contradict the established beliefs
C. the tendencies that help the newcomers to see office matters with a fresh eye
D. the ideas which usually come up with new ways of management in the organization
