fossils of the arm of a sloth. 如果后面有it的话,先指代arm,然后才是sloth,毕竟这是你前面这些名词从属结构的顺序嘛。
所以,如果it指代arm,他就不是mammal了。。

这道题正确句子的主干:
Fossils have been dated at 34 million years old.
修饰成分插入在空格位置:
Fossils _____, ______, have been dated at 34 million years old, ____.
关于A,我觉得最大的问题是主干的逻辑意思不对,提炼下A的结构:
Fossils (found ___, and dated ___,) made it _____.
第一,从逻辑上看,我用括号包围的部分应该是noun modifier that modifies "fossils", 那么这里标点符号就存在严重问题,应该是以下两种表达之一:
Fossils found ___ and dated ___ made it _____. (无逗号)
Fossils, found ___ and dated ___, made it _____. (一前一后逗号成对)
第二,还是从逻辑上看,是"
dated at ...."造成了"made sloth
the earliest known mammal ..." 这个大家都能理解吧
所以A的句子逻辑就不对,而正确句子D,恰恰体现了这种逻辑关系
至于pronoun ambiguity的问题,看这里:
http://e-gmat.com/blogs/?p=285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,见上述分析。
