A.a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of
B,D,E.略去
C.sloth that was found in puerto Rico in 1991, have been dated at 34 million years old, making this the the earliest known mammal of
1. it结构上可指代arm也可以指代sloth,但逻辑上应该指代sloth,所以导致歧义。(具体见下)
●pronoun ambiguity:
1. Understand the meaning of the sentence and determine the logical antecedent
Per the sentence:
Certain fossils were found in Puerto Rico in 1991 and are 34M years old.
The presence of these fossils indicates that sloth is the earliest known mammal of GA islands.
Thus, it will only make sense if “it” refers to “sloth”.
2. Determine if there are any other antecedents that can be referred to by this pronoun
Since pronoun “it” is singular, here are the possible antecedents – the singular nouns
• Arm
• Sloth
Notice here that both nouns play similar roles in the sentence – they describe the fossils. Thus, structurally they are at the same level in the sentence. Thus, even though it does not make logical sense for “it” to refer to “arm” since arm cannot be the mammal, structurally it still creates an ambiguity.
3. Select the Correct Answer Choice
Since the pronoun analysis shows an apparent pronoun ambiguity, we will eliminate the answer choice based on other more objective errors:
……
Choice D – Correct – The pronoun ambiguity error has been corrected by replacing the pronoun with the antecedent to eliminate the pronoun usage altogether.
我很支持这里的观点,说不要轻易用咱认为的pronoun ambiguity来作为唯一理由排除选项,因为GMAT里面pronoun ambiguity的标准没那么stringent。这题A选项的逻辑问题很严重。——babybear

2. A选项,made的主语是fossils,fossils made it the earliest known mammal逻辑语义不对。
D选项,making伴随表结果,体现了正确的逻辑关系:是“dated at ....”造成了“made sloth the earliest known mammal ...”。 作者: 651340199 时间: 2013-11-15 22:30
