Explanation:

Let’s break down these options and what’s really going on with juvenile delinquency cases in 1999:

- Option 1 (12%): That’s quite low. If only 12% were disposed by the courts, most cases would have just been hanging around, and that’s not how the system worked.

- Option 2 (29%): Still pretty low. This would mean the courts disposed of less than a third of all cases—doesn’t match the actual workload.

- Option 3 (41%): Better, but still not on the mark. The courts actually took care of more than this in 1999.

- Option 4 (57%) : This is the real answer. In 1999, about 57% of all juvenile delinquency cases were disposed by the courts. Most cases did get some kind of court action, and more than half fits what we know about how busy the juvenile courts were at the time.

- Option 5 (63%): Slightly high. While the courts did handle a lot, it wasn’t quite this much in 1999.
