Neanderthals had a vocal tract that resembled those of the apes and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.
(A) Neanderthals had a vocal tract that resembled those of the apes
(B) Neanderthals had a vocal tract resembling an ape’s
(C) The vocal tracts of Neanderthals resembled an ape’s
(D) The Neanderthal’s vocal tracts resembled the apes’
(E) The vocal tracts of the Neanderthals resembled those of the apes

答案是B
请教各位NN，“so were probably without language"中的SO是指什么？

purpleelf

so 不是连词吧这里，个人觉得是副词。and so were (they) without language，and连接had和were并列，正常语序为they were without language so, so意为同样地

谢谢，再问一下，为什么and前面没有逗号？

前半句的意思是：Neanderthals 有一个与猿相似的声带，并且可能不会说

话。
这个so表示的逻辑就是 因为N的声带和猿相似，所以也可能不会说话

A：those指代 a vocal tract 不对
C： The vocal tracts were probably without language 逻辑不对
D：同上
E：同上
