For sometime past it has been widely accepted that babies—and other creatures—learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, no otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.

Now, there are many marriages in which couples have decided not to have any children. And there are many marriages where at least some of the children are from the wife’s previous marriage, or the husband’s, or bot
A. spend some of their time with their half-brothers and some of their time with their half-sisters

C. are shared between the two former spouses
