代词指代问题

Heathrow

代词指代问题有NN的总结吗，总是弄不清楚。
如The four-million-year-old fossilized skeleton known as Lucy is so small compared with many other skeletons presumed to be of the same species, and so some paleontologists have argued that Lucy represents a different lineage.
A.    presumed to be of the same species, and so
B.    presumed to be of the same species that
C.    presumed that they are of the same species, and so
D.    that they have presumed to be of the same species, so that  
E.    that they have presumed are of the same species, and
笔记上说，DE they 无指代  C呢
谢谢了

从逻辑意义上分析，属于同一species的应该是hominids也不是skeletons，而前文没有出现hominids所以they无所指代。 楼主在考虑指代问题时，可以先从逻辑上判断代词应该指代的对象，然后看看主语或者最近的名词是不是该事物，如果是，则一般来讲指代不模糊，如果不是则指代不清。（同时注意单复数，they不能指代hominid，只能指代hominids）

谢谢你的指点。好像有点感觉了

很感谢。。。不过还想请问是看主句主语还是从句的主语，如果是并列句呢？是看最近的句子主语吗？
