The question confuses me right away because most Americans are not keeping their kids' schedules full all the time. "Go play, I have to work/cook/shop/whatever." Kids are doing "what they would do if they don't have to do anything else," because they don't have to do anything else.
Maybe the question is more about the behavior of the adult than the child? Parents need to enable their children's interests. Maybe your child really wants to roller skate but can't do it unless you enable them by watching them, because it's a dangerous neighborhood. It's your responsibility to foster their interest by making the time to help them.
Or maybe the idea is that parents sometimes don't actually know the interests of their children? So the point of the question is not to open time in the kid's schedule for their activity (because they're doing that activity already). It's to make the parent more aware of what the activity is?
