Short Leash CLOZE #3

Target Language or Knowledge:

Needless to say, the specific fears are overblown. A child is no more likely to be abducted by a stranger today than he was in the 1970s, according to David Finkelhor, director of the Crimes Against Children Research Center. Abductions have increased, but that's almost entirely due to estranged spouses or parents kidnapping their own children. What has changed over the last 40 years is our sense of community. Mothers work, neighbors talk less, and the divorce rate began to creep upward in the 1970s and has remained at around 45 percent. Rates of single motherhood have exploded since the 1980s. But that kind of change is so ubiquitous that it becomes almost invisible, so instead we turn it into a concrete evil: the creep lurking just around the corner.
