答案选D，可是在这里her work会不会没有指代，因为D中的ML是以所有格形式出现的，如OG这一题，they就不能指代investment officers’中的officers，请指教！

90. Since 1986, when the Department of Labor began to allow investment officers' fees to be based on how the funds they manage perform, several corporations began paying their investment advisers a small basic fee, with a contract promising higher fees if the managers perform well.

(A)    investment officers’ fees to be based on how the funds they manage perform, several corporations began

(B)    investment officers’ fees to be based on the performance of the funds they manage, several corporations began

(C)    that fees of investment officers be based on how the funds they manage perform, several corporations have begun

(D)    fees of investment officers to be based on the performance of the funds they manage, several corporations have begun

(E)     that investment officers' fees be based on the performance of the funds they manage, several corporations began

The clause beginning Since 1986... indicates that the practice described in the second clause continued for some period of time after it began. Choice D, the best answer, supplies the present perfect have begun, which conveys this continuity; D also uses a construction that is appropriate when "allow" means "permit": allow... to be based on. Choices A, B, and E incorrectly use the past tense began rather than the present perfect; furthermore, in each of these options, they has no referent, since officers is a possessive modifier of fees.
    Choices A and C include the awkward phrase based on how the funds they manage perform. Choices C and E incorrectly use allow that.. .fees be based

其实我觉得你说的指代不明问题不存在。 你可以试着把句子改为Leakey's contributions to archaeology include her discovery of the earliest direct evidence of hominid activity and her painstaking documentation of East African cave paintings， in addition to that she  worked on the Miocene hominid fossil record. 差不多就这个意思。 指代不明错误的原因时他会引起歧义，但在这一题这个问题并不存在。
