OQ 759. 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.

OA : D. sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on

Wrong Answer A Explaination: 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.


OQ 761. The eyes of the elephant seal adapt to darkness more quickly than any other animal yet tested, thus allowing it to hunt efficiently under the gloomy conditions at its feeding depth of between 300 and 700 meters.

OA : C. The eyes of the elephant seal adapt to darkness more quickly than do those of any other animal yet tested, allowing it

______________________________________________________________________________

Can anyone explain why the same logic of 759 is not applicable in 761?
In 761, the subject is eyes and still "it" is referring to elephant seal.

Dear fellow gmatter,

note in the elephant seal example, it refers to the seal and to the eyes. The singular pronoun "it" cannot refer to the plural noun "eyes" or "animals". Hence there is no ambiguity in this particular case.

If that helped, please give a kudo.

Hi,

In Q. 761, eyes can't 'hunt efficiently...', so it refers to the elephant seal and in Q. 759, the subject of made is sloth. Hope that clarifies a bit.
