看and后面的were without language,只有人才可能有或者没有language,声带是不可能的。
explain why they were supplanted中的they要有合理的指代对象,这就要求画线部分要出现合理的主语。此句中应该以Neanderthals为主语,杀掉CDE以tract作主语的选项。and连接的第二句因为so放句首要倒装,正常语序为:without language were probably a shortcoming that....
主语不合逻辑
The vocal tracts做主语逻辑意思不对 The vocal tracts were probably without language 错
逻辑意思错误
先排除CDE:“a shortcoming that may explain why they were supplanted by our own species.” they应该指代主语,neanderthals,所以划线部分的主语应该是Neanderthals,而不是CDE的vocal tracts。 A中a vocal tract和those of apes的单复数不对称 所以终于只剩B啦!
CDE,a shortcoming that may explain why they were supplanted by our own species,they 指的是Neanderthals
注意句尾的they,不能指代vocal tracts
