  • 第9题：

    单选题
    According to Karen Norberg, ______.
    A

    among children born out of wedlock there were more girls than boys.

    B

    the chance of a woman giving birth to a girl is higher if she has been living with a man before the child was conceived.

    C

    for parents who were not cohabiting, boys were born 51.5% of the time.

    D

    women who have not been living with a man are more likely to have daughters.


    正确答案： C
    解析：
    录音中Karen Norberg在研究中发现“the chance of a woman giving birth to a boy rather than a girl is higher if she has been living with a man before the child was conceived”，可见在他看来一个女人在怀孩子之前与一个男人一起生活那么她生男孩的几率就相对较大，因此选项D的推断正确。
    【录音原文】
    Can household arrangements affect the human sex ratio? According to Karen Norberg, of the National Bureau of Economic Research in Cambridge, Massachusetts, they can. In a review of data from almost 60, 000 American families, Dr Norberg found that the chance of a woman giving birth to a boy rather than a girl is higher if she has been living with a man before the child was conceived. To be specific, for parents who were living together, boys were born 51.5% of the time, while when the parents were not cohabiting only 49.9% of births were male. This difference may seem small, but statistically it is highly significant, which suggests it is the result of evolution.
