Young professionals in their late 20s or early 30s have been called the "boomerang generation" because of the trend toward returning to the family home.
Recent research has suggested that young people in Britain are twice likely to choose to live with their parents in their late 20s than their counterparts elsewhere in Europe.

1．C 根据本句的意思判断此处前后说的是一个意思，表现没有达到要求的标准也就意味着失败。
