558.        One of four babies are now born to mothers aged thirty years or more, compared with just one of six born in 1975. D

(A) of four babies are now born to mothers aged thirty years or more, compared with just one of six born

(B) of four babies is now born to a mother whose age is thirty or older, compared to just one of six babies who were born

(C) baby in four are now born to mothers aged thirty or older, compared to just one in six

(D) baby in four is now born to a mother aged thirty or older, compared with just one in six（D）

(E) baby in four is now born to mothers aged thirty years or more, compared to just one in six

请问B选项有何明显错误？不会只是因为one of four没有one baby in four好吧？

谢谢！

哦。。。

我自己给自己解决好了！刚发完就突然反应过来了：

B选项的whose age is thirty or older错，age不能是older,只有人才能older，就像D选项那样就可以，older修饰a mother

不知各位觉得我的分析是否有理。

one of four是四个里面的一个。

one in four是每四个里有一个--表统计数据时候要用这个。

关于age...我想是可以的吧. older 后省略的是 than thirty. 不是older age.
