16. 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 in 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 informati0n on families in which men are the sole income earners.
答案是B,
我理解是这样: 题干----7.6 m 的女性挣钱,有小孩儿, 6.4m女性是家庭中唯一挣钱者. 推出很少部分女性挣钱,有小孩儿,不是家庭唯一挣钱者.
而B答案说谬误在于高估了两个集合没有重叠的可能性.
我觉得是高估了重叠的可能性才对呀?
是否我理解有问题?
请大家指点 |
