    There is nothing like the suggestion of a cancer risk to scare a parent, especially one of the over-educated, eco-conscious type. So you can imagine the reaction when a recent USA today investigation of air quality around the nation’s schools singled out those in the smugly(自鸣得意地)green village of Berkeley, Calif, as being among the worst in the country. The city’ s public high school, as well as a number of daycare centres, preschools, elementary and middle schools, fell in the lowest 10%. Industrial pollution in our town had supposedly turned students into living science experiments breathing in a laboratory’ s worth of heavy metals like manganese, chromium and nickel each day. This is a city that requires school cafeterias to serve organic meals. Great, I thought, organic lunch, toxic campus.
    Since December, when the report came out, the mayor, neighbourhood activists(活跃分子)and various parent-teacher associations have engaged in a fierce battle over its validity: over the guilt of the steel-casting factory on the western edge of town, over union jobs versus children’s health and over what, if anything, ought to be done. With all sides presenting their own experts armed with conflicting scientific studies, whom should parents believe? Is there truly a threat here, we asked one another as we dropped off our kids, and if so, how great is it? And how does it compare with the other, seemingly perpetual health scares we confront, like panic over lead in synthetic athletic fields? Rather than just another weird episode in the town that brought you protesting environmentalists, this latest drama is a trial for how today’ s parents perceive risk, how we try to deep our kids safe—whether it’ s possible to keep them safe—in what feels like an increasingly threatening world. It raises the question of what, in our time, "safe" could even mean.
    "There’ s no way around the uncertainty, " says Kimberly Thompson, president of Kid Risk, a nonprofit group that studies children’s health. "That means your choices can matter, but it also means you aren’ t going to know if they do. " A 2004 report in the journal Pediatrics explained that nervous parents have more to fear from fire, car accidents and drowning than from toxic chemical exposure. To which I say: Well, obviously. But such concrete hazards are beside the point. It’s the dangers parents can’t—and may never—quantify that occur all of a sudden. That’s why I’ve rid my cupboard of microwave food packed in bags coated with a potential cancer causing substance, but although I’ve lived blocks from a major fault line(地质断层)for more than 12 years, I still haven’ t bolted our bookcases to the living room wall.
How did parents feel in the face of the experts studies?
选项 A、They felt very much relieved.
B、They were frightened by the evidence.
C、They didn’ t know who to believe.
D、They weren’ t convinced of the results.
答案C
解析 推理判断题。第2段中明确提到，各方都出具专家所持有的相互冲突的科研结果，家长们应该相信谁呢?从下文内容可以看出，面对专家们的研究，家长根本无所适从，不知道该相信谁，故选C项。A项“他们感到很放心”，与原文相悖；B项“他们对所提出的证据感到害怕”，原文未提及；D项“他们并不相信所提出的结果”，与原文不符。
