这个题目我觉得应该选D

E不对，因为：
原文说 Althoughlimiting information collection could increase the risk that researchers willoverlook facts relevant to a study, Frazier and Mosteller contend that suchrisk, never entirely eliminable from research, would still be small in moststudies.
这跟E选It cannot be freed of the risk that significant variablesmay be overlooked 完全相反。

请牛牛指正！
