[单项选择]Passage Two
People are living longer than ever, but for some reason, women are living longer than men. A baby boy born in the United States in 2003 can expect to live to be about 73, a baby girl, about 79. This is indeed a wide gap, and no one really knows why it exists. The greater longevity (长寿) of women, however, has been known for centuries. It was, for example, described in the seventeenth century. However, the difference was smaller then—the gap is growing.
A number of reasons have been proposed to account for the differences. The gap is greatest in industrialized societies, so it has been suggested that women are less susceptible to work strains that may raise the risk of heart disease and alcoholism. Sociologists also tell us that women are encouraged to be Jess adventurous than men (and this may be why they are more careful drivers, involved in fewer accidents).
Even smoking has been implicated in the age discrepancy. It was once suggested that working women are
A. diseases and road accidents
B. industrialization and work strains
C. their immunity to heart disease and refusal of alcohol
D. their endurance of work strains and reluctance for adventure
