问题详情
The word "caveats" (in the last paragraph) refers to______.
A．refusals by epidemiologists to examine the work of Pace and other activists
B．potential flaws in amateur studies of cancer cluster
C．warnings by activists concerning environmental dangers in their communities
D．tendencies of activists to assume environmental causes for cancer
参考答案
正确答案：B
解析：B意为：业余研究癌症患病群体的人可能犯的错误。caveat原意为“防止错误解释的说明”。这里指错误的解释。这句话的意思是：这些错误解释(指上一段提到的情况)是否意味着其他社会活动家花了很大力气做的研究都毫无意义呢?C项为干扰项，All these caveats实质上是忽略考虑环境的因素，这是专家的失误，而不是社会活动家针对群体面对的环境危险发出的警告。
