Neanderthals had a vocal tract resembling an ape's and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.

根据同位语中的they得出句子的主语是Neanderthals，B选项中a vocal tract对应an ape's.

注意后面的were

排除CDE：“vocal tracts” 和“without language” 不符合逻辑 A中a vocal tract和those of apes的单复数不对称

划线部分的主语应该为Neanderthals

supplant 代替 they要有所指 只能指代N

句子结构：N had sth....and (so) were without language. 错ANeanderthals had a vocal tract that resembled those of the apes。 A中a vocal tract和those of apes的单复数不对称

划线外的部分！！！！they were supplanted!!!!,明显平行是要求人作主语的

因为后面的 a shortcoming that may explain why THEY were supplanted by our own species里的they是复数，所以主句中的主语一定是Neanderthals，而不是vocal tracts。

开始做题时，考虑resemble必须形式也对应，其实没有必要，应该考虑一些 were without language 以及 they 更适于解释人,所以主语必须是人
