(D) by not fully considering alternative ways to classify the
(E) by not considering fully alternative ways of classifying his or her
首先,the way of doing sth 和 the way to do sth是同义的,都可以用,含义没有区别。opportunity,chance也是这样。 但E有1个问题: everyone 正式文体可以用he指代,口语可以用they指代,虽然逻辑上he/she对应everyone,但一般不用he/she指代。选项C巧妙地用the解决了这个问题,因为在这里用属格和定冠词都可以。
所以E应该为: by not fully considerng alternative ways of classifying the 或者 by not fully considering alternative ways of classifying his
