(E) between bonds and stocks on comparing bond yields with

这道题我做错了，不过看着正确答案C里的comparisons觉得长相怪异，哪位可以解释一下？是因为base on之后只能跟名词而不能接动名词么（我选的是E）？

4.     Among the reasons for the decline of New England agriculture in the last three decades were the high cost of land, the pressure of housing and commercial development, and basing a marketing and distribution system on importing produce from Florida and California.

(A) basing a marketing and distribution system on importing produce from Florida and California

(B) basing a marketing and distribution system on the imported produce of Florida and California

(C) basing a system of marketing and distribution on the import of produce from Florida and California

(D) a marketing and distribution system based on importing produce from Florida and California（D）

(E) a marketing and distribution system importing produce from Florida and California as its base

Choices A, B, and C can be faulted for putting a verb phrase, basing…, where a noun phrase is needed to continue the list of parallel elements that begins with the high cost of land, the pressure of housing… Also, the imported produce in B suggests that the system is based on the produce itself rather than on the practice of importing produce. In C, the import of produce is unidiomatic. D, the best choice, presents a noun phrase (… a marketing and distribution system ) that completes the list of parallel elements and refers to the act of importing produce. E also supplies the noun phrase but states illogically that the system imports produce as its base. The question is moderately easy.

importing pinpoints the practice while imported produce accents the "produce".

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（D）

(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.

based on+adverb clause is awkward.

可能是名词表示状态和结果，动名词表动作。做出选择不是因为比较这个动作。
