Nylenna's study showed that errors in scientific manuscripts submitted for publication often escape reviewer's notice results that were not _______: when Godlee conducted a study of the same phenomenon, her findings were similar.
A. credible
B. unwelcome
C. anomalous
D. quantifiable
E. consequential
I know the answer is C. anomalous, but cannot understand why. To make my question clearer, let's extract a complete sentence from it:
Nylenna's study showed that errors in scientific manuscripts submitted for publication often escape reviewer's notice results that were not anomalous.
My question is: what is anomalous?
From the context, it seems "Nylenna's study" is anomalous, since the same result is reproduced by Godlee. However, it should be "that was not anomalous" in this case.
Also, what is "notice results"? Is it a phrase or just two separate words?
