GWD-8-Q4请教

安然向人

C)对应的是这句话：Only in research on entirely new treatments are new and unexpected variables likely to arise.

E)对应的是这句话：Although limiting information collection could increase the risk that researchers will overlook facts relevant to a study, Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies.
排除C选E的原因：
有童鞋说选E是觉得选项中的significant和对应句子中的small矛盾。。。
对应句中的small的修饰对象是the risk of overlook facts relevant to a study, 即忽略相关事实的风险small，而非例如variations这些“相关事实”small，原文中没有提到facts relevant to a study，比如variations是significant还是small。
而C选项中的routinely与其对应句子中的unexpected都清楚的针对variations的发现，这矛盾很明显。

E仔细想想还是有道理的。。。。吧。。
因为原文出处 Although limiting information collection could increase the risk that researchers will overlook facts relevant to a study, F and M contend that such risk, never entirely eliminable from research, would still be small in most studies.

原文中的small指的risk，是说这样的 风险小。
E中significant指的是variables，所以选项significant 和原文small没有关系。

另外可以这样对应：
E：risk that significatn variables may be overlooked
原文：risk that researchers will overlook facts relevant to a study

那么significant variables = facts relevant to a study吗？

就这样先说服自己吧。。。也是摔这坑的娃。。
