问题     Kids whose moms were employed outside the home, a new study found, were more likely to have been hospitalized, had an asthma(哮喘)attack or an injury or ingested something poisonous in the last year than kids whose moms weren’t working. Not just a little more likely—twice as likely.
    The findings, soon to be published in the Journal of Health Economics, contradict other research that has found the opposite: that working moms have healthier kids(Which contradicts other research, and so on...). The discrepancy is due to the way the researcher Melinda Sandler Morrill, an assistant professor of economics at North Carolina State University, sliced and diced the available data.
    Morrill looked at the health only of kids aged 7 to 17 who had a younger sibling of about kindergarten age, so that their moms were likely to be right on the cusp(尖端)of changing their working status. She also used other difficult-to-explain statistical techniques to try to make sure that the results she was seeing were due only to the fact that the mom was working, rather than anything else. If the same mother had not been working, what would the kids’ health have looked like?
    For example, she wanted to make sure that the mothers weren’t staying home because their children were frail, which would not skew(影响)the results. Also she wanted to make sure that the figures weren’t comparing a mother who was not good at multitasking with a mother who was.
    While the headline-friendly finding could produce handwringing among working moms and a quiet smile among those whose primary job is mothering, that’s not the intended result. "I’m not trying to make a statement," says Morrill. Rather, she’s striving for a more accurate picture than the current analyses can supply. "The study provides one more piece of evidence about what happens to children when mothers work. "
    It doesn’t seem all that surprising that school-kids whose mothers work suffer more health incidents of the kinds she suggests. Injuries, poisonings, asthma attacks would logically seem more likely to happen to children who are not being minutely supervised than to those who are.
    Morrill, who declined to say whether she had kids, acknowledges that this is a possible explanation. But she was quick to add that she couldn’t say where the kids in the study were when the incidents happened—with parents, grandparents or a nanny or at day care. And the study had no information about the long-term well-being of kids with moms in paid employment.
What can we infer from the second paragraph?
选项 A、The findings of the study were published in the Journal of Health Economics.
B、There have already been a succession of similar studies with contradictory results.
C、All the other researches have found that working moms have healthier kids.
D、The researcher Morrill used a more scientific way to analyze data.
答案B
解析 细节推断题。定位段介绍了这一新研究的结果与之前研究的结果相反，括号中的内容更说明之前的研究结果也不尽一致。由此可以推断，在这之前已经有不少这方面的相关研究，但结果却相互矛盾，因此答案为B)。A)“这一研究结果发表在了《健康经济学杂志》上”，原文用soon to be published说明研究结果即将发表，而并不是已经发表，故排除；C)“所有其他研究都表明工作的母亲会有更健康的孩子”，定位段括号中的内容表明这一结果也和之前的某些研究结果相矛盾，由此可推断并非所有其他研究都得出同一结论，故排除；D)“研究者Morrill用了一种更加科学的方法分析数据”，文中并没有对其分析数据的方法是否更科学作出评判，故排除。
