39. Which of the following alternative explanations of the change in the cash value of children would be most likely
to be put forward by sociological economists as they are described in the passage?
(B) The cash value of children rose during the nineteenth century because their expected earnings over the course of
a lifetime increased greatly.
(D) The cash value of children rose during the nineteenth century because compulsory education laws reduced the
supply, and thus raised the costs, of available child labor.
B is the best answer.
According to the author, practitioners of the new “sociological economics” explain sociological
phenomena “solely in terms of their economic determinants” and “tend to view all human
behavior as directed primarily by the principle of maximizing economic gain’ (lines 85-98). This
choice provides just such an economic explanation for the nineteenth-century rise in the cash
value of children.
D uses an economic argument to explain the change, but here the economic factors at work
are the result of a change.
