78. Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles Islands.

(A) sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of
(B) sloth, that they found in Puerto Rico in 1991, has been dated at 34 million years old, thus making it the earliest mammal known on
(C) sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of
(D) sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on
(E) sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

解释A中说：Because "sloth" is the object of a preposition and not the subject of the sentence, there is no reasonable antecedent for the pronoun "it"; in this construction, the subject of made is fossils, but it makes no sense to say that the fossils made it the earliest known mammal.

难道是因为"sloth"是宾语，就不能被"it"指代吗？这句话made it读起来确实有问题，但答案的解释也想不通哦

是修饰fossils，提取主干， fossils (of ....)( found...) and (dated...), made it ..... 就很清楚了吧。。。
