问题 According to the passage, CDC is an organization that
What can be inferred from the words of Dave Forney?

选项 A、Norwalk-like viruses caused horrors among people.
B、Norwalk-like viruses can be eliminated by CDC.
C、Norwalk-like viruses casually appear on vessels.
D、Norwalk-like viruses co-exist with gastrointestinal illness.

答案C

解析 推理判断题。根据题干中的Dave Fomey定位至第三段。从该段可知,Dave Fomey认为感染了Norwalk viruses并非意味着爆发流行病。他这种情况见得多了:去年在阿拉斯加,几艘船上都爆发了类似疾病,这几乎没有引起任何关注。可见他认为这种病毒在船上出现没什么大不了的,偶尔出现而已。Dave Forney的话中没有提到人们的反应;从第二段末句可知CDC并没有让该病毒消失;第三段末句指出:就肠胃疾病而言,今年的病患人数可能比去年的少。这里没有涉及Norwalk-like viruses。
