Everyone participating in the early sociological study committed a crucial methodological error by failing to fully consider alternative ways of classifying their data.

(A) by failing to fully consider alternative ways of classifying their

(B) by failing fully to consider alternative ways of classifying their

(C) they failed to consider alternative ways to classify their

(D) by not fully considering alternative ways to classify the（D）

(E) by not considering fully alternative ways of classifying his or her

想问一下，D中的the data 在原为中并没有出现过，为什么加定冠词

his or her 可以替代前面的everyone吗？

我记得好像OG上有提到过the要指代前文出现过的对象，不过这应该不是普遍原则。用the只是特指，表示不是泛指。

罕见，而且不简洁。

说法应该可以，但是GMAT中多为错

因为his or her 是女权后出现的

正式问题一般用his指代everyone

但是GMAT这种考试中这种指代还是慎之又慎为好

我想一定有其他题点可以解题的。
