116. Approximately 7.6 million women who earn incomes have preschool-age children, and approximately 6.4 million women are the sole income earners for their families. These figures indicate that there are comparatively few income-earning women who have preschool-age children but are not the sole income earners for their families. A major flaw in the reasoning is that it (A) relies on figures that are too imprecise to support the conclusion drawn (B) overlooks the possibility that there is little or no overlap between the two populations of women cited (C) fails to indicate whether the difference between the two figures cited will tend to remain stable over time (D) ignores the possibility that families with preschool-age children might also have older children (E) provides no information on families in which men are the sole income earners 彻底没明白这题……详解里给的韦氏图也没明白…… 不知道是不是很弱，怀疑自己脑子秀逗了，汗 请达人赐教，多谢
