请教gwd8的Q4(gwd-8-4)

Q4:
According to the passage, Frazier and Mosteller believe which of the following about
medical research?

A.     It is seriously flawed as presently conducted because researchers overlook facts that are relevant to the subject of their research.

B.     It tends to benefit certain subgroups of patients disproportionately.

C.     It routinely reveals new variables in research on entirely new treatments.

D.     It can be made more accurate by limiting the amount of information researchers collect.

E.      It cannot be free of the risk that significant variables may be overlooked.

答案是E，我选了B.

E其它都不错，只是significant我拿不准。原文只是说相关的，并没有说significant。

(10)     analysis. 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

(15) from research, would still be small in most

      studies.

B确实有点牵强，我的理解是

(25) the disease under study. Often research­ers

      restrict study participation to patients

      who have no ailments besides those being

      studied. A treatment judged successful

      under these ideal conditions can then

(30) be evaluated under normal conditions.

只有某些subgroup满足ideal conditions，那treatment是successful,所以benefit；但有些subgroup不同程度地满足ideal conditions，那treatment则是disproportionately benefit.

请教各位，遇到一个选项其它都很perfect，只是某个限定词看起来不舒服，但其他选项理解起来比较牵强，应该怎么办？
