题目材料：

While data collected by the Current Population Survey (CPS) of the United States showed an increase in the annual average number of hours of paid employment for the period 1969–1987, data collected from employers showed a decrease. A probable, if partial, explanation is that employers report hours for employees at their establishment alone. If people are working longer hours because they work at more than one job, then establishment surveys may not be a good measure of workers` hours. And multiple jobholding did increase in the 1980s, especially among women. In addition, multiple jobholders tend to work long hours. It is also possible that the data collected from establishments do not adequately represent hours at all business establishments because of various data collection and response problems.

The highlighted sentence performs which of the following functions in the passage?

A.It provides an explanation for the increase in multiple jobholding in the 1980s.
B.It adds to the explanation for the increase in the annual average number of hours of paid employment indicated by the CPS data.
C.It provides evidence that the increase indicated by the CPS data is due more to men's than women's work.
D.It describes a negative consequence of the phenomenon described in the previous sentence.
E.It suggests an explanation for the collection and response problems described in the subsequent sentence.
